Compaction is the number one enemy of turf grass, particularly on heavy traffic areas. Compacted soil prevents grass roots from penetrating deep within the soil profile (grass roots grow in the air spaces between soil particles). If the soil is compacted, aeration is required.
What is Core Aeration?
Core aeration is a mechanical process by which small cores/plugs of soil are removed from the lawn. Core aeration reduces compaction of the soil by creating channels which allow oxygen, nutrients and water to get to the root system of the lawn.
Benefits of Core Aeration
- Loosening of compacted soil
- Enhancing root growth of turf grass
- Improved water uptake to turf root systems
- Easier nutrient delivery to turf root system
- Better oxygenation of soil
All of the above benefits will result in a stronger root system and thicker and more resilient turf grass.
Best Time to Aerate
The best time to aerate is in the spring and/or early fall. During these seasons, weather conditions are milder and lawns are not as stressed. This is also the ideal time to over-seed. By over-seeding after aerating, grass seed will readily collect in the pocks of the soil created by the aerator. The grass seed will now have a firm hold within the turf allowing better conditions for germination.
