Core aeration is a mechanical process where plugs of turf, thatch and soil are removed from a lawn. It has several benefits. Aeration relieves soil compaction and aids thatch management, ultimately making it easier for grass to obtain necessary water and nutrients. When combined with over-seeding, aeration stimulates root development and creates a thicker lawn. Aeration will also make additions of lime, sulphur and fertilizer more effective. Furthermore, it can reduce puddling and water runoff. Late summer into autumn is the best time time to aerate your lawn.
- Core aeration reduces soil compaction which keeps air, water and fertilizer from the roots.
- Lime or sulphur can be applied after core aeration to promote a change in pH deep in the soil.
- Aeration combined with over-seeding creates an environment that enhances thick lawn growth.
“Without aeration, nutrients from the air, water and fertilizer may not reach the soil, which can cause imperfections in your perfectly manicured lawn.”
