I have heard people say different things about when is the best time to provide the following services: aeration, dethatching, fertilizing/pre-emergent, and overseeding. I understand that it depends on what area someone is in and what grass they have, but still I haven't seen a lot of consistency in people's advice. My business provides services in north Texas. Most yards here are St. Augustine or Bermuda or a combination of the two. Does anyone have opinions or ideas on the best time of year to provide these services?
