Should I water the lawn after aeration?

• <div><p>Yes, you should water the lawn after aerating. Now that you’ve loosened up the soil to better receive nutrients, it’s time to hydrate and fertilize your lawn. You’ll want to keep it evenly moist to promote healthy growth. Don’t drown your grass—too much of a good thing can reverse all the work you’ve done with aeration in the first place. But especially if you’ve overseeded and/or fertilized after aeration, you’ll want to ensure a moist soil layer to absorb those nutrients and fuel for new growth.</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 should you not aerate your lawn?

• <div><p>There are a few time periods or conditions during which you should avoid aerating your lawn. For example, do not aerate when the ground is frozen or waterlogged, as it can damage the soil structure and grass roots. Aerating during the peak of summer heat or drought is also not recommended since it can stress your grass further. It's best to wait for cooler, more favorable conditions. Finally, newly seeded lawns should not be aerated until the grass is well-established, usually at least one year after seeding.</p></div>

Q: How do you prepare your lawn for core aeration?

• <div><p>To prepare your lawn for core aeration, water it the day before you aerate. (Alternatively, you can wait until it rains and aerate the following day.) Aerating after watering or a rainy day will make the process easier since you can penetrate moist soil better than dry soil. You should also flag your sprinklers so that you don&rsquo;t accidentally hit them while aerating. If you have a lot of thatch buildup in your yard, you might need to <a href="https://www.angi.com/articles/how-dethatch-your-lawn.htm">dethatch your lawn</a> before aerating as well.</p></div>

Q: How often should I aerate my lawn?

• <div><p>Experts recommend aerating a lawn at least once a year. If you haven&rsquo;t aerated your lawn recently, or if it has a significant amount of thatch buildup, you may need to aerate it twice annually for a few years. Keeping up with a regular aeration schedule helps ensure the long-term health of your yard. </p></div>

If I have any weeds show up, they come out and spot spray those areas. I really like that they don't spray a lot of chemicals on the entire lawn. My yard is looking great!

They are very reliable, always do good work. If the lawn doesn’t need mowing they are just fine with not charging us for that week. They remove snow for us as well. If we call them they will come out right away. They have great customer service.
