I just got a call from a client that was worried because I put on a fertilizer one month after they had it hydroseeded. Her instructions from her hydroseeder was no chemicals for 1 year. I told her I thought they were refering to weed control but I thought even then 1 year was extreme. My tech put down a 24-5-11. I admit a starter fert may have been better but can 24-5-11 possibly hurt new turf?
