Should you add Core Aeration to your lawn maintenance routine?
Sometimes you can follow all the lawn care basics – mowing, watering, fertilizing – and your yard will still need a little help. For lawns that have trouble with thatch, compaction and/or moisture and nutrient penetration, core aeration can help make your grass healthier so you can live life outdoors. These lawn care tips on aeration will help get you started.
What is Core Aeration?
Core aeration for your lawn cultivates soil much in the same way that garden soil is cultivated: By creating holes in the soil, water, air and nutrients can easily enter. You can expect vigorous root growth thanks to the increased penetration of air into the soil.
Core aeration also helps control thatch, but it can’t fix a severe thatch problem on its own without an aggressive turf grass management program. It can also be combined with overseeding.
How does Core Aeration work?
During aeration, a machine is used to extract plugs of turf, thatch and soil, creating holes in your lawn. The plugs are deposited on the surface. This process:
- Increases gas exchange in the root zone
- Improves penetration of moisture and nutrients
- Stimulates root growth
- Relieves compaction
- Helps manage thatch and prevents excessive buildup
Lawn care basics: Soil Moisture and Core Depth
In order for core aeration to be successful, the aeration machine must be able to extract a plug-or core-deep enough to benefit your lawn. The minimum depth for a pulled core is 1 inch. If the soil isn’t most enough, this depth may not be able to be reached and you will either have to water the lawn or wait until it rains to create better conditions for aeration.
When’s the best time to Aerate your lawn?
Aeration should be performed only when the conditions are right for active root growth in order to not cause any undue stress on your lawn.
- Fall aerations are preferred. When performed in the late fall, recovery should take place before dormancy. Spring aeration is acceptable as well, but it may impact the performance of preemergence herbicides. Never perform core aeration on cool-season grass during the summer heat or winter dormancy.
What is Thatch?
Thatch is a layer of slowly decaying organic matter composed of dead roots, stolons, leaves, rhizomes and other grass plant parts. This layer rests right above the surface of the soil and can either be beneficial or detrimental, depending on its depth. Detrimental thatch levels can increase insect and disease problems; decrease tolerance to heat, cold and drought; and prevent moisture from getting to the soil.
The key to core aerations rests in starting the program before thatch levels are excessive. Generally speaking, 1/2 to 3/4 of an inch of thatch is healthy for your lawn-anything over 1 inch can reduce the quality of your grass. Aerations should be used to maintain healthy levels of thatch.
