Core aeration is recommended annual or semiannual for all lawns as part of a good turf maintenance program. Hard, compacted soil and thatch take away your lawn's ability to breathe. Aeration removes thousands of small cores of soil 1″ to 3″ in length from your lawn. These cores dissolve back into the lawn after a few rainfalls, mixing with whatever thatch exists on your lawn. This also allows water, air, grass seed and fertilizer to reach the root zones of the soil. Turf roots naturally grow toward these growth pockets resulting in healthier lawn with thicker, deeper roots.
If you have been properly watering your lawn and your turf is experiencing excessive run-off, most likely the soil is compacted. Every day use, mowing, and irrigating of your lawn will naturally create compaction. Compacted soils and soils with poor drainage tend to accumulate thatch faster. Compacted soil prevents very important nutrients from reaching the grass root system. Relieving the soil from compaction will instantly give your turf a chance for long-term health. Core aeration will make way for important elements to reach the root zones of the grass. Your lawn needs water and oxygen to promote health. Any deprivation of these elements will be evident when your turf shows signs of stress.
