Aeration is essential, especially for heavy clay soils.
It reduces compaction,improve air circulation in the soil, helps fertilizer and nutrients uptake and water absorption. Hot and dry summer contribute to soil compaction. Many weeds like spurge, crabgrass, dallasgrass, dandelion thrive in compacted and nutrient-poor soil.
One of the symptoms of compaction is no matter how much you water the lawn, turf always looks thirsty.Water probably runs off, instead of going in the soil.
removes plugs from the soil and relieves pressure from the roots. it is essential for heavy compacted soils.
does not pull out soil plugs, but slices the ground and let air, nutrients and water reach the roots. It is less disruptive and can be performed more frequent. It is very effective if combined with overseeding and soil amendments.
The best time is late spring to early summer, when grass is actively growing and can recover quickly.
If you have not aerated your lawn in the spring, early fall is the time. When wet season starts, aerated lawn will be able to absorb all the rain, while a non-aerated one will flood and deprive grass roots from oxygen and encourage fungal diseases to develop in the spring.
