The benefits of core aeration is to break up the thatch layer in turf…enabling better air, water & nutrient exchange in the soil which produces a deeper root system & thicker turf.
Core Aeration ~
Core aeration removes “cores” of soil. Aeration involves making holes in the lawn either by pushing a rod into it or extracting a plug of soil.This process breaks up thatch, relieves soil compaction and improves water, nutrient & oxygen movement in the soil. The build-up of lawn thatch makes it difficult for your lawn to breathe. (Thatch is a spongy layer of light-brown matter that resembles peat moss located between the soil & grass) Lawn aeration helps control thatch.
Overseeding is simply applying seed over the top of your lawn, preferably after the core aeration process. Over-seeding regularly as part of your standard maintenance of a healthy yard keeps your turf thick & dense.
Slit Seeding ~
Slit seeding is a process where a machine will open the soil and deposit seed directly into the soil opening. This procedure is typically recommended when turf conditions are poor (large bare spots, heavy disease or damage).
