Denver Landscape Design Company Tells Homeowners When to Aerate Their Lawns

Aeration is a crucial part of taking care of your lawn in Colorado. Many homeowners may notice that over time, their lawns grow a bit thinner and shorter. This often happens because of soil compaction. Soil compaction occurs from weather such as rain and snow as well as activities that happen on your lawn, such as kids playing. When soil becomes too compacted, it can’t properly soak up nutrients. This is why it’s such a good idea to aerate.
In most cases, aeration should take place in cooler weather, such as during the spring or fall. But with the crazy weather we often see on the Front Range during those seasons, it can be difficult to make a judgment call about the best time. Here are some guidelines.

Springtime Aeration

Spring in Colorado can be tricky because your aeration plans will depend somewhat on the type of winter we’ve had. If it was a pretty dry winter, you are probably safe to aerate after a couple of weeks of warm, springlike weather. But after a wet winter that seems to be extending well into spring with spring snowstorms, it’s probably best to wait until after it appears the snow has ended for the season. But if you end up aerating and it snows again, you don’t need to be concerned. A bit of snow isn’t going to have any real negative impact on a freshly aerated lawn. What you are trying to avoid is a ton of heavy wet snow compacting your aerated lawn. 

Fall Aeration

Summers along the Front Range tend to be dry, so your lawn will need another aeration so it can breathe for the next season. Since September in Denver can be quite hot and dry, we usually recommend putting off your seasonal aeration until October. A pro tip for great results is to overseed your lawn at the same time. Fall is the best time for overseeding because it tends to have better growing conditions for newly seeded grass.

Types of Aeration

When most people in Colorado think of aeration, they think about core aeration. This is done by pulling out plugs from the law. The plugs are usually about 2 to 3 inches long. You’ll be left with a network of tiny holes in your lawn which enable the lawn to soak up everything it needs to grow. It’s a common way of aerating, but it is somewhat limited if there are spaces the machine cannot reach.

Liquid aeration is a better method because it provides more coverage. Liquid aeration essentially turns your lawn into a big sponge through thousands of tiny holes in your lawn. You can’t see these microscopic holes, so it provides a more aesthetic way of aerating. There is just one caveat to this effective way of aeration: It can take a bit longer to see results.
