Lawn Aeration 101: Why should I aerate my lawn?
The grass that you see in a typical residential or commercial lawn is a monoculture – its not something that naturally occurs in nature. Go to a meadow in the mountains, you’re not going to find just one single type of grass. Therefore, to keep our lawn healthy and allow that one culture to grow well, we must do things that Mother Nature herself doesn’t do.
The main thing we’re fighting against is compaction of the soil. Compaction comes in many forms – the watering of your lawn, the weight of snow from the winter season, etc. If your lawn is used for recreation, you’re going to have people walking around on it. As a result, the soil under lawn will become very dense, preventing oxygen and nutrients to reach the roots.
Lawn aeration opens the soil back up, allows nutrients to penetrate into the root zone, providing the grass with oxygen.
The Best Time to Aerate a Lawn
Lawn Aeration 102: When should I aerate my lawn?
Aerating your lawn can be done twice a year – once in the spring and again in the fall. For Winnipeg lawn aeration, we recommend aerating in the months of April or May as part of a spring cleanup and in September or October for fall.
Lawn aeration in Winnipeg at these times of the year is prime. During these growing seasons, the grass can easily heal and refill the plugs that have been removed.
When working with cool-season grasses, such as bluegrass, fescue and ryegrass, we recommend its best for homeowners to aerate during the growth periods in the spring and fall.
Furthermore, when aerating in the spring, have your lawn mowed a few times before aerating. Mowing the grass first will ensure the lawn is growing fast enough to recover. Take advantage of this increased pore space and air exchange at the root zone that aeration creates.
Lawn Aeration 103: What is the best way to aerate your lawn?
Search Google for “how to aerate my lawn” and you’ll find some gimmicky advice. “Just wear your golf shoes or some baseball spikes and walk around your yard.” Or they might say, “Grab a pitchfork and go out there and stab your lawn for five hours.” Hah! Who knew comedians had such great material on lawn aeration?
Proper Winnipeg lawn care requires what is called deep core aeration. We use a Bluebird mechanical push aerator to achieve the best lawn aerating results. As the aerator rolls across the grass, sharp metal tubes penetrate the soil and pull out plugs about 3/4″ in diameter and 3″ in length.
