I'm in the process of putting together a program for very shady lawns. I am going to include one overseeding with shade mix/starter fert in the spring, one summer app of 5-10-31, a fall/winter app of about 1 lb of nitrogen, and weed control year round . A second seeding in the fall will be optional. From talking to some friends and the guys at lesco, and doing a little research, I think that I want the yearly nitrogen to be around 2 lbs. What type of programs do you guys have?
