USDA FS Agriculture Handbook 727 - The Woody Plant Seed Manual, a handbook on seeds of trees and shrubs, is not available in hard copy format. But, you don't have to wait for this information. We have the April 2008 version on our Woody Plant Seed Manual page.
If you are considering planting tree or shrub seeds check this site out for more information about the preparation procedures for these plants.
For more information contact your local Cooperative Extension Center and ask for the Commercial Horticulture Agent.
