We strongly recommend aeration for all lawns once each year. Aeration reduces compaction. Compaction basically means that the soil is smashed tightly together, making it difficult for water, air, nutrients, and your grass’ roots to get down into the dirt.
Compaction can be caused by a number of things—excessive traffic, hard rainfalls, rainfalls that cause flooding and/or standing water (forcing all the oxygen out of the soil,) by sodium in your city water, or just by the type of soil you have (clay, for example.)
Aeration loosens the soil and allows air, water, nutrients, and your grass’ roots to penetrate more easily. Aeration will allow your watering to work better because it will soak into your lawn more easily. (If you notice that water always runs off your lawn when you’re watering, you really need to aerate to save on your water bill.
The Benefits of Aeration include:
- Reduced soil compaction
- Improved air exchange
- Improved water penetration
- Improved resiliency and cushioning
- Improved fertilizer uptake and use
- Reduced water runoff and puddling
- Improved rooting
- Enhanced thatch breakdown
