Aeration is generally used to combat soil compaction. For lawn care in Denver, this is especially important as soil is impacted by our climate and poor soil conditions. The rough and strange winters we have can be difficult on soil, either drying it out on the sunny days or over-watering it when it snows. In the end, winter damage effects soil compaction a great deal, and aeration is the perfect way to fix the damage done, especially as lawns here in Denver have difficulty recovering from their winter dormancy.
This means the best time for aeration is early spring, as your lawn moves out of winter dormancy and works towards rebuilding itself. Aeration is the process of excavating small holes in your lawn, allowing air and water to reach the roots of your grass and loosening up the soil, creating a healthier lawn. It is recommended one uses a lawn aeration service. However, the author can understand the desire to do things yourself. If you are looking to aerate your lawn yourself, there are a few things to remember.
First, you need to make sure you get the right tool. There are both spike and plug aerators on the market. You absolutely want to go with the plug aerator, as spike aerators can cause more damage to your lawn, increasing soil compaction rather than eliminating it. Once you have the right tool, make sure your lawn is damp before beginning. Dry lawns make for difficult aerating. It is ideal to begin aerating the day after it rains (which is rare here in Denver) or the day after watering your lawn. While aerating, make sure you go over your lawn a few times, as most aerators only cover a small portion of the lawn as you go by, and may need a couple passes to get the entire lawn. Following the aeration there will be excavated plugs of soil. It is best to let these dry and then flatten them out. The easiest way to do this is with your lawn mower next time you cut the grass.
Now that you’ve finished it is good to look at lawn fertilizers and treatment. With your lawn aerated, products like fertilizers and revive lawn treatment will have much better access to your grass’ roots, complimenting basic watering with rich minerals guaranteed to help your grass grow greener. While most think of only aerating lawns in the spring and fall, lawn care in Denver is quite different thanks to our dry climate and strong sun. A second aeration in mid-summer is a must to keep your lawn green and healthy all the way through fall.
