This summer, with the help of The Good Acre, Blia and Phua Thao put up a high tunnel on their certified organic vegetable farm. After a farm tour led by Blia and Phua Thao, where they talk about how they manage their farm (they are organically certified), what they grow and the story behind their farm, learn about the design they chose, the building process, and their fall crop selection. They will discuss irrigation, trellising, planting times, soil fertility, and pest management.

Blia and Phua Thao are Hmong farmers that own and operate Thao’s Garden, a certified organic vegetable farm in Spring Valley, Wis. Blia fought alongside Americans during the Vietnam War. After the war, he learned that he could no longer live in Laos. So in 1976, Blia and Phua immigrated to the United States with their young family. In 1983, Blia saved $15,000, which he used to buy a 4-acre farm in Nebraska. In 2003, Blia and Phua took out a $200,000 loan and moved to their current farm. They became certified organic in 2006. Blia and Phua find joy and happiness in farming because they know the food they provide is fresh, high quality, and chemical-free. Blia and Phua sell produce at farmers markets in Minnesota and Wisconsin. They also sell wholesale produce to The Good Acre Food Hub.
