How long does it take to aerate a lawn?
Lawn aeration for the average sized yard takes one to two hours to complete. The larger your yard, the longer it takes.
How often does my lawn need to be aerated?
Most lawns should be aerated at least once a year. If your soil is compacted or has a high clay content, you need to aerate twice a year. If your lawn is new, aerate twice a year until it's established. If you have sandy soil, you may be able to aerate once every other year.
When should I aerate my lawn?
The type of grass in your lawn will determine when you should aerate. If you have cool season grasses like bluegrass, fescue or rye grass, aerate during its growing season in spring and fall. For warm-season grasses like Bermuda, buffalo, St. Augustine, and zoysia, aerate between late spring and early fall. Never aerate when your lawn is stressed by heat or drought, but always when the soil is moist, so the plugs come out easily.
What's included in a lawn aeration service?
Preparation of the lawn
If your soil is dry, the lawn care professional will wet the lawn so the aerator can perforate the ground and remove those plugs. They may also mow the grass, because aeration is most effective on short grass.Some companies may require you to do the prep work yourself, or charge an additional fee if they do the prep work.
Pushing a lawn aerator through the yard
The professional will then use a machine with cylinder-shaped tines to perforate the ground and pull 1.5-inch plugs of grass, thatch and soil out of the ground. Some lawn aerators look a little like a push lawnmower. Others attach the aerator to a tractor or riding lawnmower.
Leaving the plugs
The lawn care professional will leave those little plugs of grass and soil in the yard where they'll decay in about two weeks, depending on weather conditions. The plugs help break down the thatch layer and feed the soil when they decompose, which is good for your yard's health.
Fertilizing or seeding
This generally isn't included in a basic lawn aeration service, but it's a common add-on. Aeration stresses your yard temporarily, so fertilizing helps it recover. Lawn pros may use compost to enrich the soil after an aeration service.
A newly aerated yard also absorbs nutrients more efficiently, so you get more lift from the feeding. It's also a good time to add grass seed, a process called overseeding.
