Lawn Irrigation questions, answered by experts

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.

Break up hard dirt in your yard with popular methods such as core aeration or manual aeration with a spade, mini excavator, or pitchfork. You can also alter your soil to keep it from compacting in the future. Adding compost, groundcover plants, or aeration granules—preferably made of organic materials—can also soften your ground and encourage water saturation.

In most municipalities, landscaping companies require a business license to operate legally, and some require additional licenses, like general contractor licenses. You can use Angi's our contractor licensing tool to confirm if a company in your area holds the necessary licensing. Equally as important as the license is insurance. Before hiring any lawn care company, you should confirm that it is fully insured. This measure protects you from lawsuits, and it also protects the employees in the case of an injury or unemployment.

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 typically combine liquid aeration with other lawn treatments. However, follow the specific product's instructions and consider the compatibility of treatments. In most cases, liquid aeration can complement fertilization, overseeding, or weed control programs. Combining treatments strategically can address multiple aspects of your lawn's health and appearance simultaneously. Always read and adhere to the guidelines provided by the product manufacturers to ensure safe and effective application.
