Here is what I've been doing for the last few years. Works pretty good,but... #1 Team Pro w/22% nitro. I hit it hard 5 lbs/1000 sun 20-10-10 shade 5/1000 #2 Weed control only or with Chelated Iron (NO fert) #3 35-3-7 40% sulfur coated fert Spot weeds. Grub control where needed. #4 Weed control again on weedy green lawns. On weak ones High Nitro fert #5 19-19-19 high rate 5-7lbs/1000 I am thinking changing #2 to include 1/2 lb/1000 rate of Liquid urea and applying Talstar only on round 3. Then adding 1/2 rate of liquid nitro on #4 and hitting #5 with 19-19-19 at a 6-7 lb/1000 rate. I think using fertilizer in the summer is a bad idea now. Even with 40% slow release I think it is causing problems. Does anyone else out there do anything like this, and if so, how did you turn out?
