Now is the time to start thinking about fall lawn care and preparing your lawn for next season. Aeration and overseeding is a key part of lawn maintenance.
St. Louis saw record breaking heat all summer and lawns are struggling to survive. Aeration and overseeding in the fall will bring back your lawn and thicken up your lawn and replace any grass that may have died.
Other services you may want to consider are power raking and topdressing.
Power raking will remove some of the thatch and allow the seed to make better contact with your soil. Thatch will build up over time and can cause fungus and disease problems to your lawn.
Topdressing your lawn with compost after aerating will further reduce compaction, add organic matter to your soil, and improve the micro organism activity in your soil. Topdressing your soil will greatly improve the way your soil processes nutrients and give your lawn a deeper green look.
If I were to recommend one thing to do to your lawn every year in St. Louis, it would be to aerate and overseed in the fall. Grass has a life cycle and needs to be replenished with new seed.
