The Benefit from Aeration and Overseeding
Fall is approaching in the North Star State, and that means we need to start thinking about fall cleanup and getting our yards prepared for winter. Today, we will talk about one of the most beneficial steps you can take to improve the look and health of your yard; aeration and overseeding.
After a long summer of playing and hosting other activities, your grass might start to lose its former luster. This is because, over time, our soil becomes compacted from frequent use. When soil is compact, it stops the flow of water and air into the roots of your grass. This will cause your grass to wilt and eventually die if not remedied.
Other Signs of Soil Compaction
Brown or wilting grass is just one of the symptoms of compacted soil. Here are some other red flags that should alert you to soil compaction.
Try pushing a shovel or screwdriver into the ground. If it isn’t easy, you have a problem and should consider aerating your lawn.
Compacted soils prevent water from being absorbed into the ground. Instead, it will collect in low spots and create large puddles that can become breeding grounds for mosquitoes.
Thatch is another contributor to soil compaction. Thatch is made up of layers of leaves, grass clippings, and other organic matter. When it becomes thick enough, it can block water from reaching the soil.
The Benefits of Aeration
Aeration is the process of using a machine that pulls hundreds of small plugs of soil from your yard. This alleviates compact soil and breaks up thatch. The aeration process allows for the flow of air, water, and nutrients back into the roots of your grass. It also promotes deeper root growth, which will give your grass a headstart in spring.
Aeration Has The Following Additional Benefits:
- Thicker, healthier grass
- Grass grows much easier
- Fills in bald and thin patches in your yard
- Reduces water runoff
- A healthier, stronger yard
When Is the Best Time to Aerate?
Here in Minnesota, only cool-season grasses thrive. Cool-season grasses perform well in areas with cold winters and mild summers. These grasses do their growing in the spring and fall when temperatures are cooler. The most common types of cool-season grasses in Minnesota are Kentucky bluegrass, fine fescue, and perennial ryegrass.
Aeration should be done during the growing season of the grass, either in the spring or in the fall. This will ensure that the grass has time to repair itself and get the most out of the process.
Spring aeration provides quicker green-up, while fall aeration promotes stronger roots.
The Benefits of Overseeding Your Lawn
Overseeding is a process done after your yard has been aerated. Overseeding is simply the addition of new types of grass seed to your existing lawn. Benefits of overseeding include.
- Filling in bare spots
- Thicker grass
- Weed prevention
- Resistance to pests, drought, and lawn diseases
- Improved appearance and color
