Aeration
Aeration is the process of mechanically removing small plugs of thatch and soil from the lawn to improve
soil structure and reduce compaction. Most lawns have a layer of thatch (dead plant material). Normally,
thatch is not a problem until it becomes too thick. Then this layer reduces moisture and fertilizer
from reaching the root zone. Prevention is the best medicine.
What are the benefits of aeration?
Core aeration helps the lawn's health and vigor, and reduces maintenance requirements. The following are other benefits of core aeration:
- Reduces compaction of soil which allows grass to produce a stronger,
healthier root system. Stronger roots will always be a great benefit to your lawn.
- Fertilizer can get down to the root system more readily.
- An aerated lawn will absorb more water
- Reduces water runoff and puddling.
- Aeration breaks up the thatch layer. Annually aerated lawns will
almost never develop a damaging thatch layer.
- Enhances heat and drought stress tolerance
- Improves resiliency and cushioning for your feet.
When should lawns be aerated?
Annual aeration is beneficial for all lawns. Lawns growing on heavy clay or subsoil, and lawns exposed to intense use, benefit from two or more aerations each year.
Early spring and early fall are ideal times to aerate. We generally recommend aerating after spring green up. Aeration, in combination with fertilization, enhances root growth and improves spring green-up.
