When should I Core Aerate?
Core Aeration if best done in the Fall. Also, when the soil has moisture and is not too hard. When you Core Aerate in the Spring, the soil cores laying on the surface are exposed to sunlight and there is a chance to promote more weed growth in your lawn. If you Aerate & Overseed in the Spring, it is best done early which provides a very small window of opportunity. In the Fall, weeds are done germinating and you get the most out of your core aeration. It is also a great time to overseed. Keep in mind, it is never really a bad time to aerate and your lawns needs should determine when and how often. A sodded lawn needs Core Aeration to break down the peat layer and to encourage oxygen, water and roots to break down into the soil beneath.
