Aeration rejuvenates your lawn allowing it to breathe more easily
Opened airways in your lawn allows water, air and plant nutrients to reach the roots more quickly

Soil plugs removed during aeration will break down and provide additional nutrients to your lawn
Combine aeration with over-seeding and it can revitalize thinning or older lawns
Aeration helps reduce watering requirements. By relieving soil compaction water penetrates is increases and water run-off is reduced
