They were very attentive, professional, and accommodating, especially for our unexpected Sunday morning emergency. They not only repaired the leak but also addressed another issue that had arisen with our shutoff valve. Their estimate was very reasonable and accurate, and their work is top-notch.

Lawn Irrigation questions, answered by experts

There are several best practices you can do to keep your lawn looking healthy. Knowing when to water grass is among the most important. Having your sprinkler timer set to early morning is best because it gives your grass and plants enough time to absorb water before the sun and wind can evaporate it. To maximize a sprinkler’s impact, aerate your lawn once or twice per year. Doing this achieves better absorption and stronger root systems for your grass.

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.

Raking only moves soil, leaves, and debris around on the surface. Aerating your lawn addresses compacted soil. Core aeration loosens up the soil, which makes it healthier and creates more verdant grass from the richer nutrients and stronger root systems that develop. Raking only provides short-term benefits, while aeration creates higher-quality soil and grass growth in the long term. Rake or dethatch before aerating for a bigger benefit to your lawn.

Lawn care is tough work—even when you hire pros, there’s no guarantee your grass won’t die (unless, of course, your company offers a guarantee). But lawn care companies don’t control the rain or watering restrictions. Your type of grass also impacts the type of care required to keep a lush lawn—and how much that care costs. Talk to a lawn care pro to determine the best times to treat your lawn based on type of grass and your climate.

The length of time it takes to aerate a lawn mostly depends on the yard's size. Generally, a lawn care professional can aerate a lawn that is 10,000 square feet in size in about 30 to 45 minutes. This process may take additional time if you have a heavily sloped or uneven yard, and it may cost extra for the lawn care pro’s labor and time.
