Creeping, warm-season turf grasses such as Bermudagrass and Zoysia are particularly inclined to build up a layer of thatch. Thatch is an accumulation of dead leaves, cut grass clippings, dead roots and miscellaneous debris. It settles at the soil level of the individual grass plants that make up a lawn and prevent water and nutrients from reaching the roots. Crabapple LandscapExperts recommend Core Aeration as the best way to counteract thatch.

What is Core Aeration?
Core aeration is the removal of small cylinders or “cores” of soil from compacted lawns (especially those with a layer of thatch), creating spaces that allow the rain and fertilizer applications to soak into the root zone and the roots of the turf to breathe and expand. The hollow tines of an aeration machine pop out ½ inch diameter tubes of soil about 3-4 inches long, and deposits them on the lawn where they soon dissolve.
Spring is Ideal for Core Aeration of Warm Season Turf
March through July
Your Crabapple LandscapExperts Rep can evaluate your turf and recommend this procedure if needed. Some indicators include: a thatch layer thicker than ½ inch; underlying soil is heavy clay; the lawn is heavily used causing thin areas; or if the turf is only shallowly-rooted.
The best time to Core Aerate a Bermuda or Zoysia lawn is March through June/July when warm season grasses are emerging from winter dormancy and beginning a vigorous period of growth as the soils warm up. Maximum benefit and fastest recovery occurs when lawns are aerated at this time.
Core aeration is not recommended on newly-seeded lawns. For complete details contact your Crabapple Rep today to schedule this beneficial horticultural practice and improve the growth and look of the lawns on the properties you manage.
