Lawn Irrigation questions, answered by experts

No, it's not a good idea to put grass seed directly on top of dead grass. For successful germination and growth, grass seed needs good soil contact. To prepare the area, start by removing the dead grass using a shovel or a sod cutter. Then, loosen the soil, add soil amendments if necessary, and spread the grass seed evenly. This allows the seed to come into direct contact with the soil, promoting better germination and establishing a healthier lawn.

The frequency of lawn aeration depends on factors such as soil type, grass variety, and lawn usage. In general, it is recommended to aerate cool-season grasses like Kentucky bluegrass or fescue once a year during the fall. On the other hand, warm-season grasses such as Bermuda or zoysia benefit from aeration in late spring or early summer. However, it's essential to assess your lawn's specific needs, as signs of compaction and reduced grass health may indicate the need for aeration outside these general guidelines.

Aeration typically takes 1-2 hours, depending on the size of the lawn and the equipment used.

Yes, aerating your lawn will help grass grow. Pulling out soil plugs or applying liquid aeration solution allows more air to circulate around the roots. A well-aerated and hydrated root system is the foundation your lawn needs to grow green and lush. Even if your lawn is healthy, annual aeration will keep it beautiful each season.

Water the lawn thoroughly, apply fertilizer, and overseed if necessary to promote healthy growth.
