For the last 54 years, the Allen Soil and Water Conservation District has provided its popular Tree Seedling Sale to the public. It offers a low-cost source of plant materials to anybody, not just residents of Allen County. This year, there are 19 types of trees available for purchase. The plants are 1-to-4-year seedlings, or 4-to-6-year transplants. They range anywhere from 8 to 18 inches in height at the time of pick up.
