Lawn Irrigation questions, answered by experts

Technically, yes—and you may have some successful growth—but this isn’t the ideal way to fill in sparse areas. By clearing leaves and debris, amending the soil, and aerating it properly before you lay the seeds, you’re providing the most ideal conditions for them to germinate.

Before you put down grass seed, you should cultivate your soil or add two inches of topsoil. You should also put down fertilizer at the same time as your seed to prompt healthy growth. Be sure to water after you put down grass seed, especially for the first two weeks.

Whether you’re putting down fresh seed or reseeding, there are a few things to keep in mind when seeding your lawn. Be sure to choose the correct seed for your climate, seed at the right time of year, and water two to three times a day for the first week. Generally, Dudley recommends seeding in spring and fall as it is usually cooler and rainier.

Pros provide deep, even aeration with machinery inaccessible to the DIY homeowner.

Depending on the lawn treatments, the best times of the year to redo your lawn are between mid-August and mid-September for overseeding and renovation treatments. For areas such as the southern United States, lawn aeration works best during the fall, when the temperatures begin to drop. Otherwise, early spring is your next best bet because the grass is fresh and ready to absorb nutrients, and the temperature isn’t hot enough to fry the grass and the renovation materials.
