You must keep documentation that the seed planted during your transition meets these requirements as part of your application for organic certification. If you plant a corn seed treated with captan after two years of transitioning to organic, for instance, you must restart the 36-month clock on your transition, to the day you planted that seed on that field. If you are unsure if a seed treatment is allowed, ask MOSES, or the organic certification agency you are planning to use when you become certified for organic production.
If your operation is certified organic, you are required under the organic regulations to plant organic seed, unless you cannot find an “equivalent organically produced variety” in the form, quality or quantity that you want. For example, you may want organically approved clay-coated carrot seed for ease of planting, and it is not available on organic seed; or, you want 1000 pounds of bodacious sweet corn seed and you cannot find organic seed in that quantity; or, the germination rate for the organic barley you found is only 65%; or, you cannot find the specific variety of seed in an organic form that the buyer of your crop wants you to grow. In all of these cases, you can use non-organic seed. It cannot have prohibited seed treatments, as described above.
Note that the rule requires you to seek out an “equivalent” variety. If you are new to organic and are unsure whether the organic seed varieties are equivalent to the familiar non-organic varieties you are used to growing, you should trial out organic varieties with similar characteristics at the same time as planting your untreated non-organic seed, to see if you can find one to your liking. Higher price is NOT an acceptable reason to avoid planting organic seed.
Organic seed is an investment in our future as organic producers. Since organic seed is produced under organic management, and the seed breeders are specifically working to provide characteristics that organic crop producers need, it makes sense to purchase from these companies and support their efforts. For example, organic corn producers cannot plant in cold ground in the early spring, since their seed is not treated with fungicides. Therefore, they want a seed that will germinate quickly as well as canopy thick and early to help with weed control in their organic fields. Organic seed breeders work to have crops that respond well to natural, slower release forms of fertility inputs, whereas nonorganic corn seed breeders don’t do this.
Aphids are sucking insects that weaken plants by sucking up sugars and other fluids from crops. They are not easy to see, since they are the same color as the plant stem and generally like to feed on stems, buds, and underneath leaves.
Step one for control is to monitor your crops on a regular basis. Infested plants are often stunted and can be a lighter green or yellow. Look closely at the stems under the leaves for aphids. A magnifying glass or loop can help. A good approach that saves time is to flag “sentinel” plants. Mark plants in a grid pattern and only monitor those specific plants on at least a weekly basis. If you find significant numbers of aphids on these plants, you know it is time for control options. Yellow sticky cards are another good monitoring device. Adult female aphids have wings and are strongly attracted to the color yellow, which mimics the color of sickly plants. The cards are coated in sticky glue, which traps them. Check cards at least weekly for signs of adult aphids. Sticky cards need to be replaced frequently to work well. Fortunately they are cheap and available through any greenhouse supply company.
If you have any infested plants in a greenhouse or high tunnel, you should begin control options since their numbers can explode quickly.
Here are your options as an organic farmer:
There are a number of predators and parasites available for purchase and release. Ladybug larvae are the most familiar, but there are parasitic wasps, lacewings and others available now as well. Biological controls work best to keep aphid levels down, but may not give good control if you already have a problem. They simply cannot reproduce as quickly as aphids (which can actually reproduce without males- females give birth to clone daughters). Beneficial insects work best as preventative controls. A number of companies sell beneficial insects, including:
Soapy water will kill aphids. The soap strips away their waxy cuticle and they die of dehydration. In order for this to work, they must be directly sprayed with the soapy water. Use a sprayer and mix one tablespoon of liquid soap per gallon of water. (Dr. Bronner’s is pure soap. Be careful not to use soaps with perfumes, dyes or other synthetic additives.) There are also many ready-to-use brands that are OMRI listed including the common Safer Insecticidal Soap.
Allowed Chemical Sprays
Remember that all insecticides approved for organic use are “restricted use” products. You can use them only when your other control options have failed, and you must notify your certifier if you intend to use a new product and the reason you must use it. Pyrethrum/pyrethrin-based sprays will work on aphids, but have a very short residual effect and must come in contact with the aphids. The product Pyganic works well, since it is pyrethrin mixed with oil, which coats and kills aphids and many other insects. Your certifier should be able to provide a list of approved pyrethrum/pyrethrin sprays or check the OMRI website for a list: www.omri.org.
Aphids also love plants that are over-fertilized with nitrogen. If they are a constant problem despite other control efforts, you might be adding too much nitrogen to your potting mix or through fertilizer applications. A tissue test to determine nitrogen levels may be in order if you are having ongoing issues with aphids and other sucking pests.
As always, crop rotation and good sanitation practices can help control aphids in the long run.
Yes, you can plant non-organic strawberry plants and sell the fruit as organic with no waiting period, provided you have documented a search and could not find commercially available organic strawberry plants.
The requirement for planting stock is similar to that for commercially available organic seeds. You must use an organic version unless you cannot find it in the variety, quality or quantity that you need. You must document your search for organic strawberry plants or other types of planting stock. If you cannot find them in the type, quality or quantity you need, then you can plant non-organic plants and sell the fruit as organic.
In February 2013, the National Organic Program (NOP) updated guidance on whether or not “planting stock” such as strawberries, raspberries, tree fruits, and herb plants needed to be under organic management for one full year before selling the production from these plants as organic. Many certification agencies had required a year of organic management. With the update, the NOP clarifies that the one year of organic management is only required when a grower is selling the planting stock itself as organic.
You can sell strawberry fruit as organic at any time from a non-organic strawberry plant. However, the runners from that plant must be under full organic management for a year before you can sell them as “organic planting stock.” Also, you can sell rosemary or lavender leaves as organic from non-organic plants recently planted on your organic farm, but you must manage the plant organically for one full year before you can make cuttings and root them to sell as organic plants.
At farmers’ markets, where these exempt-from-certification growers often sell products, labeling can become an issue. It is unfair to producers who go through the strict requirements to achieve organic certification to see the label misused. In many cases, misuse is a result of ignorance, not malice. But, it can cause bad feelings between growers at a market, and impact a market’s reputation if patrons see “organic” being used loosely.
To ensure that vendors at a farmers’ market are using “organic” correctly, managers can ask them to sign a statement that they have followed organic rules. This not only makes vendors aware of the standards they must meet, but also satisfies certified organic farmers that their market neighbors are meeting the same strict rules.
The statement below covers many of the requirements that a smaller scale grower or livestock producer must meet in order to sell organically labeled products as a noncertified (“exempt”) organic farmer. It provides information on what practices and inputs are allowed in order to use the organic label, and can be a valuable educational tool.
Farmers’ market managers should feel free to modify this statement and have it reviewed by their own legal counsel. This type of statement should be updated each year to keep current with changes to organic regulations.
NOTE: Anyone may file an anonymous complaint at NOPcompliance@usda.gov to report someone who is making an organic claim who is not certified or exempt from certification requirements.
Statement for exempt-from-organic-certification producers to use the word “organic”
I am a producer that is not certified organic, but I use the word “organic” to describe my products or practices in the marketplace. The list below describes many of the requirements in the organic law that I follow in order to use the word “organic.” I have read and follow the full U.S. organic regulation, which is located at www.ams.usda.gov/nop.
I affirm that:
1. I sell less than $5,000 annually in organically labeled products.
2. I have not planted any seeds that had synthetic treatments, such as fungicides or insecticides.
3. I have planted all organic seeds if they were available in the variety and quantity I required.
4. I have either grown transplants myself using only OMRI* or organic certifier organically approved potting mixes and other inputs or I have purchased certified organic transplants.
5. I have only applied fertility, pest, disease and weed management inputs that have either been approved by OMRI or by an organic certification agency. I understand that there are numerous agricultural input products that make organic claims that are untrue and I have gone the extra step to verify what I am using meets the organic law.
6. I have implemented a soil building rotation on my farm, where annual crops of the same type are not grown in succession in the same field. I also use plant and livestock based materials such as cover crops and compost to continually improve my soils.
7. I have not applied manure to my fields growing crops for human consumption any sooner than 90 days before harvest for crops that are not in contact with soil (i.e. sweet corn), or 120 days before harvest for crops that are in contact with soil (root crops, tomatoes, peppers etc.).
8. I have documentation that compost containing livestock originated components used on my farm meets the requirement of having a Carbon to Nitrogen ratio of between 25 to 1 and 40 to 1, has had a temperature maintained of 131 to 170 degrees F for 15 days and has been turned 5 times, or if in a static vessel, had this temperature maintained for 3 days.
9. All mammalian livestock has been managed organically from the last third of gestation of their mother to the day of slaughter. All poultry has been managed organically from the second day of life. Organic management includes 100% certified organic feed.
10. All livestock has had access to the outdoors, with ruminants receiving 30% of their nutrition from pasture during a minimum 120 day grazing season. All animal health products and feed supplements have either been OMRI approved or approved by an organic certification agency.
11. I have maintained documentation that verifies what I have stated above.

We have Canada thistle growing in the large aisles in our two-acre asparagus patch. What can we do to manage this perennial weed?
Canada thistle is a difficult weed to control—I have also dealt with it on my farm in annual crops. I am going to give you a variety of options. Timing and persistence are very important in all of these options.
Dig Them Out
I know this is very time consuming and difficult. The time to do this is as early in the spring as you can see the thistle, preferably when it is still just a rosette and has not yet started to grow a vertical stem. The length of the stem of the plant relates to the depth of the root—the taller the plant, the longer the root. So digging when the plant is very young gives you a better chance of getting the whole root.
Dig when the ground is soft and moist. You want to get the whole root. At the bottom of the Canada thistle root, there is a piece of root that is horizontal to the vertical tap root. I call this an anchor. When you get full root, including that little anchor, then you know you have gotten the whole root. REMOVE the thistle from the field and either fully compost them, or burn them on a burn pile. Thistle roots are very resilient and can re-sprout quite easily. I use a garden fork to dig out the thistle rather than a shovel. This way I don’t break the roots. Leather gloves are another essential tool when digging thistle. I do this in the early morning over a 2-week period in the spring. You can really make a lot of progress, even with just one hour a day.
If you have a handheld flame burner, you can burn them. Again, this needs to be done in the rosette stage and would probably need to be done 2-3 times in the early spring. This is faster than digging, but still needs persistence!
Smother With Mulch
Unfortunately, mulching is not the best method, unless you have a very thick mulch for 3-5 years that truly does not let the thistle receive any sunlight. The root will still be getting nutrients and moisture, so you may just weaken the root, but not destroy it. Black plastic mulch might work best; but make sure you don’t use a woven landscape fabric, which would still allow nutrients and moisture to keep those roots viable.
Smother With Cover Crop
I have had success with this on my farm, and I know corn/soybean growers have also had success with this on a larger scale. Plant sorghum-sudangrass with a drill or some way to cover the seed lightly after broadcasting it. Use very shallow tillage to prepare the area if you need to, but as little as possible. When the thistle is about 2-3 feet tall or starts to bud in your thick stand of sorghum-sudan, go in and mow it. It’s very important that you DON’T LET THE THISTLE GO TO SEED! This mowing cycle can be done 2-3 times in one season. This causes the thistle root to lose a lot of its vitality.
The reason this works well is that the sorghum-sudan is very thick and grows so quickly that the thistle can barely compete for nutrients, water and sunlight, and must use up the nutrients from its root stores. When you cut it, the cycle starts again.
Thistle also likes compacted soil and the incorporation of all of this mowed organic matter loosens up the soil and changes the soil environment so it is less “attractive” for the thistle to grow. I’ve had about a 65-85 percent reduction in thistle in one year with this activity. Then the following spring I go out and dig or burn what is left.
Mow the thistle continually through the season, keeping them 6 inches or less. This will also weaken the roots, but is not as effective as the other options above.
Soil Health, Nutrient Balance
Having a well-balanced soil nutrient profile, especially with the use of high calcium lime or gypsum to bring up low pH soils, will also reduce compaction. Do some soil testing, and compare trace nutrients in the areas where the thistle is present and where it is not. You might be surprised to see some nutrient deficiencies in the thistle areas that you can work on correcting.
Herbicide Approved for Organic
There is an herbicide called AllDown, that is approved for use on organic land. It is a blend of acetic acid, citric acid and garlic juice. Again, it must be used in the rosette stage to be effective, although they advertise it as being effective on larger weeds, too. I do not have personal experience with this product, but others have told me that it works best on the smaller thistle. The manufacturer is located in Minnesota: 952-368-0020 or www.summersetproducts.com. This is the only herbicide that is approved for use in organic production that I know of for use on thistle.
As you can see, there are a variety of strategies to control thistle. You can do one or more of these at the same time to get long term control. It may take 2-4 years of persistent effort, but you can get ahead of thistle in your organic system!
Before you take drastic steps, determine if the damage is at an economic threshold where you need to take control measures. Knowing the life cycle of the pest bothering your vegetables will tell you if the population numbers can rise very quickly, or if they tend to lessen over time. Your understanding of the insects’ needs and dislikes will help you manage them over time. In a war where only numbers are considered, insects tend to win. In a war where knowledge is the main weapon, humans have the upper hand.
The organic regulation has a pest control hierarchy that mandates you start with cultural, biological or mechanical practices to manage pests, weeds and diseases. When those don’t curb the problem, you can use natural products. After that—but only as a last resort—you can use synthetic materials that are on the National Organic Program’s National List of Approved Substances. Use of synthetics should be avoided as much as possible; broad spectrum insecticides kill beneficial pollinators or predatory insects along with problem insects.
Organic agriculture is a system of production, not just a way to grow food by substituting organically approved materials for non-approved ones. Keep track of problems you have had in the past and seek out resistant varieties (cultural control). Grow habitat beneficial to insects that prey on your pests (biological control). And, use exclusion devices like netting or floating row cover (mechanical control) to protect the tender young plants so favored by insects.
Research has shown that insects favor weak and stressed plants; healthy plants are less attractive to pests. Try foliar feeding your plants with a fish emulsion and seaweed blend to boost their immune system, both to help them recover from the insect damage and to discourage further infestation. Consider starting a regimen of foliar feeding when your plants are usually stressed, such as right after transplanting, when they flower and when they set fruit. Improving the health of the plant also helps you achieve higher yields of quality crops.
Another management technique is to plant a trap crop that is highly favored by your problem insects, and then spray an approved pesticide only on that crop. If you need to move to your last resort of approved synthetic materials, check out Peaceful Valley Farm and Garden Supply’s pest solution chart (www.groworganic.com/weed-pest-control/organic-pest-control. html). This cross-referenced chart of problem insects and control materials is very useful.
As you learn more about insect life cycles and how insect pests interact with your environment, you can help your plants become less vulnerable to insect problems.
The most protected space on our farm, which sits high on a windy ridge, is tucked in southeast of our big pole shed. We can fit two 10 x 60 structures in this protected space. To make our temporary greenhouse more secure in the high spring winds, we spaced the PVC bows closer together than is usual, and added more rope to hold down the plastic. We also added some Lexan polycarbonate sheeting remnants that we received from a generous friend. We used those below the hip board to add stability.
Another great, easy structure for this same purpose that’s even more secure can be made with galvanized steel chain link fence rails bent as bows that are more sturdy than PVC. (Learn more about this structure at www.youtube.com/watch?v=5yBHaNqrbtI.)
We rolled the sides up and down depending on the weather, and entered through one place on the wall. Doors are better and make a more comfortable entry, but we got in and out without too much trouble.
Inside this house, we built 2-foot high tables with wood frames and polycarbonate panels offset for drainage. The tables are balanced on cinder blocks. We tried tables covered in poultry wire, but these were too unbalanced; the wire would inevitably sag in one area. Instead of heating the air, we heat the tables that the plant flats sit on. It’s more efficient all around, and especially in this hack system that isn’t extremely airtight.
We’ve tried table-heating two ways: first with electric heat mats and, second with radiant roll-out heat mats that operate with an on-demand tankless water heater system that runs on propane. Water, mixed with glycol, runs through the tubes in the heating mats within this closed system that keeps the water temperature between 90 – 120 degrees F, a relatively small differential. Keeping the soil temp level and warm enough does far more for good germination and the early days of seedlings than air temp.
We have an exhaust system, and a few makeshift fans in the greenhouse, but the downside of this system is definitely controllable air-flow. For our early growing purposes it hasn’t mattered. Also, with climate change bringing earlier spring, by the time good air flow makes more of a difference, we’ve been able to open up the sides and allow the spring winds to blow through.
Our favorite low-cost system for starting plants early (February) is to build a mini tunnel inside the larger greenhouse. We attached electric conduit (available at home improvement stores for about $2.50 for 10 feet) to the tables, and put plastic over the conduit for a mini greenhouse inside the larger greenhouse. On super cold nights (-10 outside) we threw some sheets and blankets over the whole structure and kept the soil temps above 55.
The average cost to build a caterpillar tunnel is about $700. The set up for the electric heat mats was about $600. We could fit 22 flats on the mats. The cost to build the radiant roll-out heat mats that operate with an on-demand tankless water heater is about $700, not including the mats. We got mats from a former farm for a really good deal. They’re also available online through BioTherm along with the hardware needed to set up the system. (See www.biothermsolutions.com/products/microclimate-tubing). We have run about 700 square feet of tables on one water heater, fitting about 350 flats. The folks at BioTherm would be able to help you work out what you need.
I can also share a couple of watering hacks that have improved our farm life:
We set our newly seeded and just germinated trays in open flats without drainage, then fill the flats as needed for watering. It’s a little tricky to get the balance of how much water to add to the flats given cloud cover, but with a little time and practice you get the hang of it. This improves germination as we seed many flowers that sit on top of the soil and require light to germinate. It also prevents disease and fungus because we aren’t spraying water on the leaves and top of the soil.
Once the plants are large enough to handle a little more adversity, we hook up the PVC pipes with 1/16-inch holes drilled into for easy overhead watering. We only do this when we get to the point where we need to be in the field and are spending less time in the greenhouse. It’s not ideal because the plants aren’t getting the same amount of water, but it’s a functional hack.
There are many, many more greenhouse hacks especially in larger systems. These hacks have been great solutions to challenges on our new farm without requiring a lot of capital.
I am washing roots, squash and other vegetables for short- and long-term storage. Is there something I should add to my water to help them keep?
There are three common wash water additives used for washing organic vegetables. One is food-grade hydrogen peroxide, 35%. This should be diluted down to 3% in the wash water. That would be one part 35% H2O2, to 11 parts water. This product is corrosive, so handle it at full strength only when wearing long rubber gloves and goggles. H2O2 can degrade organic materials, bacteria, and organically approved or non-acceptable pesticide residues.
Another product is peroxyacetic acid, with Tsunami, a brand name for this blended product. Use this at dilution noted in the instructions. It is advisable that a final clean water rinse be done after the use of hydrogen peroxide or peroxyacetic acid before putting into long-term storage.
Let the root vegetables mostly dry before putting into storage. Some producers put these in large food-grade plastic bags in open-top totes to retain some moisture. Periodically check to make sure the roots are not too moist and getting moldy. For very long storage, you want some moisture so the roots do not dry out. Packing root vegetables in clean, slightly damp sand also works.
Chlorine also can be used, but only in fairly low concentrations. The organic regulations require that the effluent after washing contain no more than 4 PPM chlorine, which is the level allowed in drinking water. You can have your concentrations higher when washing the produce, but the chlorine must basically all be consumed and volatilized by the action the chlorine has on the bacteria and organic matter in the water. This makes the use of chlorine on a small-scale farm more problematic, since you will need to test the waste water to verify you meet the regulatory requirements.
First, you need to make sure that they are actually fruit flies. Fruit flies are often confused with a different insect called a fungus gnat. Fruit flies have red eyes, a round body and tend to hover or fly pretty slowly. They are slower moving while walking on the ground, too.
Fruit flies need overripe, damaged or rotting fruit in order to feed and breed. They are also known as vinegar flies, and are attracted to the smell of acetic acid (rotting fruit and vegetables). If you keep these materials out of the greenhouse, you are not likely to have fruit fly problems. Clean up damaged fruit and remove ripe fruit as soon as possible. The old baited fly trap with vinegar and a little soap works well to reduce their numbers, but you have to control the food source with good sanitation to get rid of fruit flies completely.
If your sanitation is good, and you are still seeing small files, they are likely fungus gnats. Fungus gnats are quite fast, both in the air and on the ground, are more thin bodied and do not have colored eyes.
Fungus gnats breed in the organic matter of soil mixes that are kept too wet and thus breeds molds, which the fungus gnat larvae feed upon. The solutions to control fungus gnats are to avoid overwatering plants in the greenhouse, improve drainage, and allow the potting soil to dry in between each watering.
Fungus gnats are not harmful to plants, but the conditions they like are also the same conditions that can lead to fungal and bacterial diseases.
Either fly problem is best solved by cultural techniques, rather than approved sprays.
I know I am supposed to plant organic seeds if I sell my crop production as organic. How do I accomplish this?
The National Organic Program (NOP) mandates the use of organic seed for crops that will be sold as organic unless you can show that you could not find the quality, quantity or equivalent variety of seed you wanted to plant. Under no circumstance can seeds treated with GMO nitrogen-fixing bacteria or non-approved synthetic fungicides or insecticides be used when you sell your crop in the marketplace as organic. This rule also applies to producers who sell less than $5,000 in organically labeled products, making them exempt from organic certification (but not from following organic standards). If prohibited materials are used on the seed, or a GMO seed is planted, the land cannot be used for organic production for three years.
More and more seed companies are developing organic seed varieties that function well in organic systems to meet the demand of the organic marketplace. By supporting organic seed suppliers, you encourage further research and development of organic seeds that compete well with weeds, grow vigorously with slow-release fertility inputs and are resistant to disease and pests. Also, certified organic seed would never have prohibited seed treatments.
An excellent resource for finding organic seed of all types is the website www.organicseedfinder.com. Field crops, vegetables, fruits, herbs and flower sources are all listed. This website is also helpful for finding seed suppliers that would be the most likely to carry organic seed varieties.
A broader list of organic seed suppliers is in the Upper Midwest Organic Resource Directory. The “Seed Suppliers” section lists not only suppliers of seed, but also farms that supply seed potatoes or grow crops for seed. The directory also is available in print. You may request a copy by calling the MOSES office at 715-778-5775.
If the specific variety of seed you want is not available, you are required to purchase organic seed of an equivalent variety. If you are unsure if the organic variety is similar or equivalent, consider purchasing some organic seed and trialing out new organic varieties to see if they do as well as the non-organic seed that you are used to growing. Remember, the NOP does not consider price to be a valid reason not to purchase organic seed.
If you plant untreated non-organic seed, you will need to document why your search for organic seed was unsuccessful—quantity, quality, and variety are all valid reasons for buying non-organic seed. For example, the organic seed only came in one-ounce packets and you wanted to purchase 20 pounds (quantity). Or, the organic seed germination rate was only 20%, and the non-organic seed had a germination rate of 95% (quality). Or, you wanted to grow an orange oxheart tomato, and could not find it from at least three sources that typically sell organic seed (variety). Searching at your local garden center which does not typically sell organic seed is not considered a viable organic seed search by most certification agencies. You should be trying to find organic seed from the many suppliers that offer it. Even a search on the Internet for organic seed varieties can be fruitful.
Organic seed can be in short supply. It is a good idea to start your organic seed searches in winter and not wait until late spring when they often are sold out.
I would like to purchase an older sprayer that had been used with prohibited synthetic materials. Can I do this and use this sprayer to apply products approved for organic production?
Yes, you can purchase and use this sprayer. However, you will need to perform some cleaning and refurbishment activities and document these before you may use it on organic land.
Most certifiers recommend a clear water rinse first. Completely fill the tank and spray it until empty on non-organic land. Second, fill the tank again with diluted household ammonia, such as one quart of ammonia per 125 gallons. Run this through the sprayer again on non-organic land. Perform another clear water rinse as above. If you continue to smell the residues of the prohibited chemicals, do another ammonia and clear water rinse again. Poly tanks are porous so you may need to repeat this procedure a few times.
Replace all rubber parts including hoses, washers, and nozzles with new ones, as these are very difficult to clean completely.
Many certifiers require that once you have converted this piece of equipment from non-organic to organic production, you can no longer use it for spraying prohibited materials. In other words, if you are sharing this piece of equipment with a non-organic farmer, or you manage split production on your own farm, you may need to dedicate this sprayer, once cleaned, to organic and not go back and forth between organic and non-organic use, even if you perform this cleaning activity each time. Check with your certification agency on its policy for sprayer use to see if it mandates dedication to organic.
As we enter the time of mid-summer bounty, the pollinators and beneficial insects are busy sipping up the nectar and pollen from your flowering plants. Nectar provides energy, and pollen is high in protein. If you are managing bees, you’ll want to research specific mixes of flowering plants that provide a good balance of both nectar and pollen. If you are a farmer who wants to make sure your farm’s beneficial pollinators have plenty to eat, you have a variety of options. Nature provides a diverse assortment of plants that flower from early spring into the fall, ensuring a good food supply for pollinators all season long.
Your first option is to ensure you have plenty of perennial and native plants on your acreage. Buffer strips of native prairie flowers and grasses are a functional and beautiful addition to larger acreages; perimeter buffers work well on smaller plots. Native flowering plants and perennials not only feed pollinators throughout the season, but also hold soil from erosion and buffer your land from neighboring farm chemicals. These plants also are easy to maintain and tolerate a wide range of climatic conditions.
Establishing native prairie and perennials can take a few years. A good resource to help you in this endeavor is the Organic Broadcaster story “Native prairie plantings can be established without using herbicides” by Harriet Behar, MOSES Senior Organic Specialist. You can find it online at https://mosesorganic.org/native-prairie-plantings.
A shorter term option to feed your pollinators is to plant annual flowering cover crops on your land that will grow fast, while improving soil and feeding wildlife, but winterkill to be easily tilled in when spring comes. Diversity of cropping not only feeds your pollinators, but cover crops are a great source of green manure and biomass for your soil. All of the following crops will die over winter and be ready for spring tillage.
Calendula – For small to medium acreages, this useful flower is easy to grow, and blooms its pretty head off all season long. When the flowers die, it can be mowed, then will come back and flower as many as three times during the growing season.
Sunflowers – There are many single stem and branching varieties with various grow times, some as fast as 60 days. You can seed them in July and enjoy them in September until the frost. Sunflower heads make a great bird feast during winter, while holding soil from erosion. Note: don’t leave over winter in a field you’d like to plant early because the thick stems will take some time to break down after spring tillage.
Buckwheat – Buckwheat is a wonderful warm season cover crop. The flowers attract many different beneficial insects and birds. It germinates well and canopies quickly to suppress weeds as it matures in 70-90 days. Buckwheat is also reported to extract soil phosphorus.
Phacelia – Another wonderful cover crop for large or small acreages, this flower is highly frost tolerant and loaded with pollen, or protein. It germinates in 5-10 days, grows fast for weed suppression, and has excellent ability to accumulate and recycle excess nitrates and calcium. Plant phacelia with overwintering crimson clover for a cocktail that will not only feed pollinators during the end of the season (phacelia), and also fix nitrogen and feed pollinators in spring (crimson clover).
Cowpea – A heat-loving legume, the cowpea or black-eyed pea not only suppresses weeds and sources nitrogen in the heat of the summer, it has “extrafloral nectaries” on petioles and leaflets that beneficial insects love to eat. Cowpeas can be planted with sorghum Sudangrass, which they’ll climb. The two together create a lot of biomass. Make sure to plant cowpeas in July at the latest, as they are not frost tolerant and require 60-90 days to mature.
Organic farming is a long-term process. Always start the year before by planting a good cover crop, something that will over-winter and return in spring like cereal rye, clover or vetch. If that didn’t happen, or if you’re farming your acreage more intensively, you can also start with a spring cover crop like a mix of field peas and oats. You can research your cover crop options to find the best mix for your soil needs. A good place to start is with the MOSES fact sheet “How to Choose Cover Crops“.
To ensure optimal nitrogen value and also create a good amount of biomass for soil microbes without allowing the cover crop to set seed, incorporate the cover crop in early to mid-June. By starting early, but not too early, you leave yourself enough time to work out many of the residual weed seeds in your field. Incorporate the cover crop the first time, then wait 10 days or so and work your field again, by tilling, cultivating or plowing, using whatever machinery and method you usually use for bed prep. Depending on the weather (always), you’ll ideally get another nice weed flush right before you plant. Prep your bed as usual right before planting by cultivating or tilling, then plant your brassica transplants.
The nutritious vegetable that they are, brassicas are heavy soil feeders. Making sure your soil macronutrients are balanced is key. Nitrogen, phosphorus and potassium levels need to be balanced, and not too high or low. Trace nutrients like manganese and boron can also make a big difference in the quality of your brassica crop. Soil tests (soiltest.cfans.umn.edu, uwlab.soils.wisc.edu) applied to fertility practice are important to start with because it’s really hard to make drastic changes in your soil chemistry at any time, especially in the thick of the season.
Some symptoms of out-of-balance soil resulting in nutrient deficiencies:
• Light yellow color and/or premature head formation also called “buttoning” can be a nitrogen deficiency.
• Too much nitrogen can cause the plants to grow too fast also resulting in a hollow stem.
• Large pest infestations can mean your plant isn’t healthy and can’t defend itself.
• Iron can inhibit calcium uptake, causing localized browning.
• Phosphorus deficiency, especially when the phosphorus can’t move in the cold of later fall, can cause the plant to turn purple.
• Boron deficiency can cause a hollow brassica stem, and browning and uneven heads.
Starting with healthy transplants is always essential to healthy produce. One of the most difficult parts of growing fall brassicas is having to care for the transplants in the greenhouse while you’re in the thick of summer harvest. Starting the seeds in a good soil mix, watering consistently, and applying a foliar feed or root drench fertilizer to boost your brassica plant’s health prior to transplanting can make all the difference in the health of your final product. Another option is to create a healthy seed bed in the field, seed with your varieties and bare root transplant from that. For more on this, see extension.umn.edu/garden-yard/vegetables/growing-broccoli-cabbage-and-cauliflower-in-minnesota.
If you’re buying seed varieties as most produce farmers do, ask the farmers in your area what has worked for them, and also try a few different varieties to find what works for you.
When the plants are in the ground, the best way to balance deficiencies is to either side-dress or foliar feed the plants. Going back to those soil tests and symptom list, you can know what you might need to attend to the health of your growing brassicas and create a mix of fertilizer and minerals in a hopper to be side-dressed once or twice throughout the growth life.
Companies such as Midwestern Bio-Ag can work with you to read your soil tests and provide inputs to balance your soil. You can also try a few different products to find what works best.
At our farm, we foliar feed our brassicas weekly with a fish emulsion mixed with Photo Mag, both OMRI-approved applications. Our soil was in conventional production up until last year, and shows some deficiencies in most everything, including the trace minerals like boron. It’s been really important to give those brassicas feeders good additional nutrition as they grow this season.
Your primary piece of equipment to ensure long-lasting flowers of most varieties is a cooler. You need to be able to take the field heat out of the flowers and hold them until delivery at about 40 degrees.
One easy and inexpensive option is to build your own cooler. Many flower growers build relatively inexpensive 8×12 coolers using foam insulation, a store-bought 18,000-BTU window air conditioner, and a “CoolBot”—a $300 piece of machinery that helps the A/C unit to cool the space to as low as 35 degrees.
Cleanliness of all your tools is of utmost importance. The “godmother of flower farming,” Lynn Byczinski, likes to say, “Keep your vases as clean as your teacups.” The same goes for buckets and clippers. Install an easily accessible, easily cleaned bucket-washing station. Certified organic growers can use biodegradable soap for washing, along with a little bit of bleach or hydrogen peroxide for sanitizing. Wash and sanitize your buckets after every use.
Many flower growers use hydrator and preservative in the water, but the research is unclear on whether or not these make a difference. Hydrator helps the stems take up water efficiently from the first cut, ensuring longer vase life. Preservatives have a sugar to feed the flowers, and a bactericide to kill the inevitable bacteria produced—the “slime” that you see in a vase of old flowers. There is one hydrating and preserving product on the market that certified organic growers can use called Vita Flora (vitaproducts.com/floracare.html).
Once you’ve installed a cooler, and have your squeaky clean buckets and clippers, the next step is timing your flower harvest. Flowers keep best when harvested in the cool morning or evening. In the morning, flowers are most turgid and very fresh. In the evening after photosynthesizing all day, they have the most carbohydrates to give them a long life. Either way, it’s best to harvest in temps under 80 degrees, while steering clear of times when dew is on the flowers. Wetness on the petals can lead to disease and fungus during storage. If you harvest in the morning, it’s important to hit that sweet spot between when the dew dries and the day gets too hot.
Every flower has its own peak time to harvest to ensure longer vase life. For example, sunflowers can be harvested and kept in the cooler the moment the first petal lifts from the center. That’s not the case for dahlias, which won’t open any further after you harvest. You’ll want to get to know each flower’s peak harvest time. Learning the ins and outs, and likes and dislikes of each specific flower can take years! That’s why it’s so important to work with other growers as you begin flower farming on your own. (Consider applying for a flower mentor through our Farmer-to-Farmer Mentor Program.)
The importance of cleanliness in flower harvest and handling can’t be emphasized enough, and that continues into how you cut and strip the flowers. Again, start with clean clippers. Most flowers can be cut and stripped in the field for efficiency and speed. But, if it has been especially rainy and the stems are muddy, you may want to cut the flowers and bring them to your processing area to strip the leaves and clean them up.
As you harvest, strip and put your flowers in buckets. Keep the harvested flowers in the shade, never in direct sunlight, and deliver to the cooler frequently as you go. Taking that field heat out of the flowers as quickly as possible after harvest does wonders for their longevity.
A few flowers do better when they’re not cooled, most notably, the zinnia. Zinnias like to be in the shade, but not cooled, and never harvested when they’re wet. I’ve learned that the hard way; they’ll turn to mush in a day or two.
You can ensure the continued longevity of your certified organic flowers when they’re out of your hands by educating your customers. Let them know to keep vases as clean as teacups, and replace the water and rinse the stems daily. To achieve even longer vase life, customers can give the flowers a fresh cut every other day, and display them out of direct sunlight. You have given your beautiful local, certified organic flowers a great start. By following these few easy tips, your buyers can enjoy them for several weeks.
I buy only certified organic ingredients for a food product that I roast and blend in order to sell a finished beverage to the public. I sell more than $5,000 a year of this product. Can I label it as organic?
The word organic on a retail food label is a guarantee to consumers that the entire process, from seed through field production, storage, sales and any food processing is reviewed and approved as meeting the organic regulations. Since you sell more than $5,000 per year of product that you wish to sell as organic, as the processor, you must be certified in order to use the word organic on the product label.
Organic ingredients alone are not sufficient for using the word organic on a product—the processing facility also must be certified organic. A certified food processor goes through a similar annual certification process as a farmer or rancher.
If you choose not to be certified, you may identify which ingredients are organic on your product’s ingredient list. However, you cannot label the finished product on the principal label as organic, nor use the USDA organic seal on the package.
To label your finished beverage something like “Organic Roasted Vanilla Coffee,” all ingredients or inputs either must be certified organic or on the National List of approved ingredients if they are synthetic. Recipes for each product you wish to label as organic, along with the production methods, needs to be included in your Organic System Plan that a certification agency will review.
Sanitation and pest management materials and protocols must also be documented. Processed organic food products have their own sections on the National List of approved pest control inputs, sanitation products, ingredients and more. Reviewing an organic certifier’s organic system plan will provide you with the information you need to prepare the necessary documentation if you decide to become certified. Pay special attention to the organic regulation section on labeling, which specifies the colors of the USDA organic seal, font size of the word organic and placement of your organic certifier’s name.
If you grew, processed and sold less than $5,000 in annual sales of organically labeled products, then, under the small operator exemption from certification, you could label the product as organic without going through and achieving organic certification. You would still need to follow all of the organic regulations, including use of approved sanitation materials and processes, approved pest management strategies, documentation that all ingredients were either certified organic or on the National List, etc. Again, a review of a sample Handler Organic System Plan would help you prepare and maintain the records you need to have to meet the law. You still could not use the USDA organic seal on your package—that is reserved for certified organic operations only. Most organic certification agencies have Handler Organic System Plans on their websites.
The National Organic Program regulations are here: https://www.ams.usda.gov/rules-regulations/organic. Since each product and process is unique, it would be best to contact the MOSES Organic Answer Line if you have more questions.
