Ask an Organic Specialist: Orchard Answers

How can I transition my existing orchard to organic?

Answer by Organic Specialist Rachel Henderson:

For people considering organic certification, it’s commonly understood that you’ll have to change some of your management practices. When the crops you grow are annuals, it seems fairly straightforward that once you begin your three-year transition, you will grow those crops under organic management. But if you are thinking about certifying crops from perennials—tree fruit, small fruits or berries, or nuts—it can be more complicated.

People focus a lot on inputs when talking about organic. While that’s only one of many factors, you will need to look closely at what you use for managing pests and disease as well as fertility. If you’ve been using Integrated Pest Management, or IPM, you may find that some control methods you’re currently using will still be allowed while others will not. Having an early conversation with a certification agency call help bring clarity to the changes you’ll need to make. It’s also a good idea to ask some questions from the places you buy your inputs. Good vendors have a very thorough knowledge of OMRI-listed products and will have some suggestions for replacements.

If you’re thinking about making changes to a perennial planting, inputs are only a small piece of the puzzle. Other questions come into play, and many seem more difficult to understand.

The National Organic Program (NOP) requires growers to use organic seeds and planting stock. This confuses a lot of people when it comes to perennials. Perennial planting stock can be certified after a minimum of one year in organic management. Newly planted trees would be subject to the organic requirement. Growers who have purchased perennial plants are likely aware that there are very few certified organic nurseries. Many organic orchardists are unable to find the selection, quantity, and quality that meets their needs from certified nurseries. Just as with planting annuals from non-organic stock, you will need to provide evidence during your organic inspection that you searched for organic stock and couldn’t find it.

Your existing orchard will need to be managed organically through a three-year transition when you can’t use any prohibited materials. After that, crops from those trees/bushes can be certified organic. You will be asked to provide information about the origin of the trees, including the source nursery and dates planted in addition to yearly treatment.

As you certify an existing orchard, another area of concern is groundcover. For conventional growers, herbicides are often the easiest way to deal with weed and grass competition. The quest for effective and inexpensive organic herbicides is unending, but at this point, there are not very good options for this.

Many organic growers use some kind of mulch under trees. Organic mulch sources are more common than organic herbicides, with woodchips being preferred by many growers. There is often confusion about woodchips, and some growers have spent a lot of time and money attempting to source certified organic woodchips. This is not necessary. Woodchips must be free of treated or painted lumber, and you’ll need to have a verification form from the source. This means that woodchips from, for example, your local dump won’t be allowed. But tree trimmers, utility companies, or wood processors are generally able to provide that verification.

You can use landscape fabric in perennial plantings, but you will need to source higher quality—more expensive—fabric than you would for annual plantings. It should be rated to 20 years or more. You’ll be asked to look for signs of deterioration and replace it before it starts to fall apart (likely way before those 20 years).

If you commonly seed groundcover or cover crops in your orchard, you will need to make sure that your seed is allowed. If you have a standing groundcover that’s managed organically through your transition, obviously you don’t need to worry about the source of that seed. But as you replace trees or find areas of groundcover that need rehabilitating, make sure that you are purchasing seed that’s allowed, whether it’s grass, clover, or another understory species. Generally, that means certified organic seed, but if organic seed is unavailable, you will need to get verification that the seed is untreated.

Can I sell organic fruits and vegetables from plants and planting stock I buy at my local garden center?

Answer by Organic Specialist Harriet Behar:

You probably will not be able to buy plants at your local garden store. When using annual transplants (tomatoes, peppers, onion plants etc.), the plants must be certified organic in order to sell organic produce from them in any given crop year.

The land you raise them on must be free of prohibited materials for 36 months prior to your first organic harvest. If you have planted nonorganic annual transplants in the same fields in the past, your certification agency may consider the land to be nonorganic, and require you to wait three years after that planting to have your first organic harvest. This decision may depend on whether the plants were bare root or were transplanted with their nonorganic potting mix. There is some difference between certifiers.Some allow one year to pass and others require three years. The interpretation of this regulation is something you want to discuss with your certification agency if you are requesting organic certification for the first time.

Your transplants cannot be purchased from an “exempt from certification” (under the $5,000 limit) operation. They must be certified organic, grown by you or someone else who has a valid organic certificate. Some natural food stores may be able to provide you with an organic certificate for the plants they sell, but most garden centers do not sell certified organic transplants.

You can grow the transplants yourself, using approved planting media which does not contain any synthetic fertilizers, fungicides, wetting agents or other prohibited materials. These items are not mandated to be listed on the label of commercially available potting media, so you must get information in writing from the manufacturer detailing the ingredients, stating that the media has not been treated with prohibited fungicides, insecticides, etc. There are many organically approved potting mix and input suppliers. For resources, see the MOSES Resource Directory or the OMRI Products List (www.omri.org)

Be very careful when purchasing any fertility input or potting mix, since the word “organic” on these items does not always mean the same thing as “approved for organic production.” Long before the USDA organic regulation, the word “organic” on a label meant it contained the element carbon. To find products you can use, you must look for the OMRI seal and the words “approved for organic production.” Always verify with your organic certification agency that whatever you want to use is acceptable before you buy it.

For fruit trees, raspberry bushes, or other perennials, you are mandated to search for organic planting stock. However, if you cannot find the variety, quality or quantity you want as organic, you can use non-organic planting stock. You must document this search.

In a recent National Organic Program guidance it was clarified that an organic harvest from non-organic planting stock can be done immediately after beginning organic management and planting into organic soil. However, you cannot create and sell organic planting stock from parent nonorganic stock until it has been managed organically for 12 months. For example, you can plant non-organic strawberry plants and harvest an organic crop that same year after planting (after failing to find commercially available organic plants) whether you manage the strawberries as an annual or a perennial. If you buy a non-organic tarragon plant, you can sell the tarragon as organic immediately after planting in organic soil, but could not make cuttings and sell those as organic tarragon plants for 12 months.

Items such as potatoes, garlic, and sweet potatoes (in other words, roots, tubers, rhizomes, shoots, leaf or stem cuttings) are subject to the organic search, and can be planted as non-organic if none were found. However, each year there is more and more availability of these items as organic, and your search must truly cover not just your local store, but also the many mail order and internet operations that sell these items.

I can’t find enough certified organic blueberry plants to upscale my certified organic berry farm. What do you suggest?

Answer by Organic Specialist Jennifer Nelson:

The National Organic Program defines planting stock as “any plant or plant tissue other than annual seedlings, but including rhizomes, shoots, leaf or stem cuttings, roots, or tubers, used in plant production or propagation.” The NOP regulation applies to the details of the growing methods of the plants. Certified farms must use organic planting stock, bulbs, roots and cuttings except when these are not commercially available. If you cannot find your preferred blueberry variety, or can’t get sufficient quality or quantities for the scale of your operation, you can use non-organic planting stock.

As with all seed and planting stock searches, you have to provide your certifier with good documentation of your search. And of course, price cannot be a consideration for determination of commercial availability.

Each year, the availability of certified organic planting stock grows. More varieties, better quality and bigger quantities become available. It’s the age-old high school economics supply-and-demand lesson in action.

To find planting stock, you can Google “certified organic planting stock” for your area, or “certified organic blueberry plants,” using the specific variety you‘re looking for. This will help you find local plant nurseries that carry certified organic plant stock. Another great resource may be the organic growers in your area. Networking with the other certified organic growers in your area can be a great benefit in many ways to everyone involved.

If you’ve exhausted all your options for finding the variety, quality and quantity that you need, and you’ve kept really good records of your search, you can begin to explore other options. NOP regulation states that you can purchase a non-organic plant and sell its fruit the next day as certified organic fruit with some exceptions—the regulation is in the details. If the purchased non-organic plant has been grown in planting media containing any synthetic fertilizers, fungicides, wetting agents or other prohibited materials or has been treated with prohibited fungicides or insecticides, these are prohibited substances, and so the fruit cannot be certified organic. Not only that, if you introduce these prohibited substances to your certified organic soil, you may risk needing to re-transition your soil for another 36 months.

Buying non-organic bare-root plants rather than potted plants is the best way to avoid these unwanted materials. If you can verify and document that your bare-root planting stock hasn’t been treated with any prohibited materials, you can plant the new planting stock in your organic soil and sell the fruit as certified organic.

Only the fruit can be sold as organic. The planting stock, crowns or bulbs off the newly purchased non-organic plant must be in your certified organic ground, grown according to NOP regulation for 12 months before the plants can be sold as organic. Since most perennial fruit-stock will not produce a commercial crop the first year of planting, this probably would not be an issue.

For example, after failing to find commercially available organic plants, you can plant non-organic blueberry plants and harvest an organic crop that same year after planting. However, you cannot sell any excess planting stock as organic blueberry plants for 12 months.

Ultimately, the search for certified organic planting stock is similar to the search for seeds. You have to keep good records of your steps. And while it’s best to find and support certified organic suppliers, you have other options if you’re unable to find what you need. As with all certification questions, call your certifying agency to be sure of what you’re bringing into your certified organic farm operation. 

Can I plant non-organic strawberry plants, and then sell the strawberries as organic?

Answer by Organic Specialist Harriet Behar:

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.
