Lawn Irrigation questions, answered by experts

Many factors can cause your yard to have lawn depressions. Here are the most common reasons: 

  • Heavy rainfall 

  • Wild animals such as moles, voles, and groundhogs that burrow and tunnel

  • Poor drainage

  • Buried items such as pipes that break down

  • Decaying tree roots or stumps

  • Soil that has compacted

  • Improper mowing techniques

  • Driving heavy equipment and vehicles through the yard

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’t accidentally hit them while aerating. If you have a lot of thatch buildup in your yard, you might need to dethatch your lawn before aerating as well.

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.

Experts use precise equipment to break up compacted soil, promoting healthy root growth and nutrient absorption.

Yes—hiring a professional lawn care company is worth it if you don’t have much free time to devote to lawn care. Lawn care pros will ensure that your lawn receives the vital nutrients it needs to grow and thrive, and you’re guaranteed to have a healthy, beautiful lawn. Aside from that, it’s a convenient service that frees up your time so you can do the things you love and enjoy.
