What causes lawn depressions?

• <div><p>Many factors can cause your yard to have lawn depressions. Here are the most common reasons: </p><ul><li><p>Heavy rainfall </p></li><li><p>Wild animals such as moles, voles, and groundhogs that burrow and tunnel</p></li><li><p>Poor drainage</p></li><li><p>Buried items such as pipes that break down</p></li><li><p>Decaying tree roots or stumps</p></li><li><p>Soil that has compacted</p></li><li><p>Improper mowing techniques</p></li><li><p>Driving heavy equipment and vehicles through the yard</p></li></ul><p></p></div>

Can you seed existing grass?

• <div><p>Adding seed to existing grass is often <a href="https://www.angi.com/articles/overseed-lawn-guide.htm">known as overseeding</a>, as opposed to reseeding. Reseeding refers to the process of filling in bare or dying patches of lawn—or in some cases, full lawns—whereas reseeding supports existing lawns to prevent thinning. Overseeding is an ideal annual lawn care practice for grass fighting drought, disease, weeds, or pest issues.</p></div>

Q: When is the best time to aerate a lawn?

• <div><p>The best time to aerate a lawn is when there's plenty of moisture in the soil, which is the <b>fall or spring seasons</b>. However, keep in mind that lawn aeration isn't very effective when there has been a long period of heavy rain, as the excess water can potentially damage the lawn in the aeration process. Wait until your lawn is predominantly dry to start the aeration process to ensure best results.</p></div>

Q: How do you rough up soil for grass seed?

• <div><p>The easiest way to rough up soil to accept grass seed and provide the best opportunity for its growth is to make several passes over the area with a garden tiller and rake away the loosened vegetation and debris. However, in some cases, very hard ground may require using a shovel or pick to break up pieces into smaller chunks that the tiller can handle more easily. </p></div>

Q: What is better: spike or core aeration?

• <div><p>When it comes to combatting the effects of soil compaction, core aeration does a far better job for a longer period of time&mdash;because it actually removes dirt rather than just pressing holes into it. By taking dirt out from under your lawn, core aeration allows more light, air, water, and nutrients to penetrate into the soil below and help your grass&rsquo;s roots grow even stronger.</p></div>
