Curate the manicured lawn of your dreams. High traffic areas of lawn get compacted with thatch over time, depriving roots of water and air, but that doesn''t mean they can''t spring back to life. A firm step onto the Manual Lawn Coring Aerator will remove 3-inch plugs, letting those precious resources reach deep into grass roots. Leave the cores on the lawn surface where they can break down and provide rich organic material back into your lawn.
