Broadcasting Sunflower Seed
Is there a basic calculation to determine how many pounds of seed to plant per acre? or per a particular size space? A friend asked me about growing sunflowers as I had great success one year, although failed the following three years. The method I used was broadcasting, but I don't recall how many seeds to use. I did tell him, more is better, because the birds will do a great job of thinning them out. Thanks for any suggestions.
