I currently aerate lawns in the Chicago area. Lawns are mostly Kentucky Bluegrass along with some Ryegrass and Fescues. Many of my customers use ChemLawn/Truegreen and they are not totally pleased with their service/prices. I do not want to become a licensed/insured pesticide applicator. So I need help in designing an application program. I like the idea of corn gluten meal for crabgrass and broadleaf weed protection applied in the spring (early April) 20lb/1000ft2. End of May, a commercial grade lawn food with a biostimulant (21-3-5) fertilizer which contains micronutrients. Beginning of fall, corn gluten meal 20lb/1000ft2. Fall, aerate and topdress with a compost/top soil mix-1/2 inch per year. Has anyone used CGM on lawns after typical chemical pesticides regiments? Was there a noticable increase/decrease in weed population, turf color, turf density, etc? I would like some feedback before I select a program.
