Aerating your garden lawn is a simple, yet effective way to improve drainage and alleviate compaction in heavily trodden areas. Grass is a living thing and needs air and water to grow and thrive. Routine mowing and other garden activities, lead to compaction in the top layer of the grass. Garden drainage is obstructed and it's much harder for water, air, and fertiliser to seep into the roots. This garden rolling aerator will allow nutrients to saturate the soil to promote healthy and lush garden growth. Self assembly is required. Quick to assemble.
