His prices are excellent, and he has always gotten back to me. He got me in his schedule quickly, and the workers were very thorough and did not rush through the job. This is the second time we have used him, and hope to use him for a variety of requests at our home. Highly recommend."

Lawn Irrigation questions, answered by experts

The grass could be dying because it’s overwatered or underwater. Additional issues include over-mowing the lawn, compacted soil, or a fungal disease in the lawn. In many instances, regular maintenance can keep grass from dying.

Each type of grass has its own specific needs regarding the timing of aeration, but in general, late summer to early fall is the best time to do so. For most lawns, that means sometime between September and November, though certain types of grass, like St. Augustine Grass, do better with aerations in late spring and early summer.

Using specialized equipment, they aerate thoroughly, alleviating compaction and enhancing root health.

Experts typically recommend aerating your lawn about once per year, but your aeration frequency will depend on your soil type, lawn condition, and other factors. For instance, you should aerate annually if you have clay-heavy soil or frequent foot traffic in your backyard. However, if your soil is loose or sandy and you don't use your yard often, you can probably aerate every other year.

Professional lawn care can increase your home’s value, as it beautifies your exterior and improves curb appeal. Potential buyers who pull up to a house that looks neat and clean will get a great first impression, and savvy buyers will know that a well-maintained exterior is probably indicative of proper care for other things, like electrical, plumbing, and HVAC systems. Ultimately, a lawn that’s professionally cared for can boost your home’s appearance and lead buyers to offer more for your house.
