Once to twice a year.

Aeration Benefits:

• Loosens compacted soil and increases the availability of water and nutrients.
• Enhances oxygen levels in the soil, stimulating root growth and enhancing the activity of thatch-decomposing organisms.
• While removing cores of soil, the spoons or tines also sever roots, rhizomes and stolons. Grass plants are stimulated to produce new shoots and roots, which "fill up" the holes in the lawn and increase the density of the turf.
• Reduces water runoff.
• Increases the lawn’s drought tolerance and improves its overall health.
