Aeration is the process of mechanically removing small plugs of soil and thatch from the lawn to improve growth of the turf. Lawn thatch is the layer of dead turfgrass between the green vegetation and the soil surface that must be removed to maintain the lawn health. A thin layer of thatch is desirable because it helps insulate the grass from extreme heat and cold.
The aeration will also break up the compacted Georgia clay soil allowing air, water, and nutrients to move to the root system more efficiently. Because Warm Season Turfgrass such as Bermuda and Zoysia have above and below ground root systems the aeration process will also help the turf to spread and thicken. Everywhere the aeration process cuts the root a new growth will sprout allowing the lawn to thicken.
Benefits
- Enhances water, fertilizer, and oxygen penetration for a healthier lawn
- Reduces water runoff
- Reduces soil compaction
- Improves grass roots
- Thickens the lawn
Why should I aerate my lawn?
With repeat aerations over time, your lawn will show enhanced heat and drought tolerance. Lawns that are aerated regularly will be healthier, more vigorous, and easier to maintain and have fewer pest problems than lawns that are neglected.
When should lawns be aerated?
The best time to aerate Warm Season grasses such as Bermuda and Zoysia is in the spring, end of April thru June. Lawn aeration should be done every year to improve the total health of your lawn. Lawns with heavy traffic or heavy clay should be aerated more frequently (1-2 times a year).
What to expect
After the lawn has been aerated, the grass will be covered with small plugs. In about a week or two, the plugs will break apart and disappear.
