I have an account that has had Lawnmaster spray for two years to get their lawn back from weeds. This is my first year doing her lawn and it's in fairly good shape. She wants to not spray any more chemicals than she has too. My answer for her was that we would mow properly, higher and more often as needed, and fertilze (after a soil test) to keep a healthy lawn, and see how it goes with the weeds. Am I on the right track? I am almost ready for the pesticide test, and only want to fertilize as I believe in using the least amount of chemicals. Can you really keep ahead of most weeds by just keeping the lawn healthy?
