Lawn Irrigation questions, answered by experts

You can try that, but it isn't likely to yield results. It's like watering potted plants without putting the seeds in. Most of the tossed grass seeds sit on top of the soil or existing grass blades and never germinate. The seeds need to make it into the soil, just like growing a potted plant. The best way to accomplish this is to aerate your lawn first, then overseed.

Lawn aeration and dethatching are meant to solve the same problem, loosening up compacted soil so that the root systems can grow and receive more water, oxygen, and nutrients. Aeration is the gentler option and often the preferable one. Dethatching completely tears out the thatch layer of the lawn and can inadvertently yank out healthy grass if done incorrectly. Aeration loosens the soil and only removes small cores of it.

While you may see some germination by simply tossing a handful of new seeds on a lawn, you'll have more success by following the proper reseeding or overseeding process step-by-step. Without properly tilling, mowing, amending the soil, and watering your lawn, the new seed could blow away or simply fail to take root.

Yes, you can throw seed on a lawn and hope it grows, but taking a few steps beforehand, such as dethatching, aerating, or raking, will give the seed a better chance of germinating. While it sounds like it’ll save time, throwing seed on the lawn without doing anything will require much more seed than any other method.

They handle labor-intensive tasks efficiently, equipping your lawn for seasonal changes without physically demanding work on your part.
