I have a contract with the local lds churchs in my county (24 buildings). They also have a contract with chem lawn doing all there fert. My problem is every time they fertilize the grass grows crazy for 3-4 weeks. On average 4-6 inches a week, a few growing 8 to 10 inches in a week. This puts me way out of my budget. I need to talk to the manager and would like some input before I do this. this is the biggest contract i have so this is important to me. Where is the limit for you guys before you have charge more?
