Lawn Irrigation questions, answered by experts

Aerate during the growing season, typically in spring or fall, when grass can quickly recover.

The grass could be dying because it’s overwatered or underwater. Additional issues include over-mowing the lawn, compacted soil, or a fungal disease in the lawn. In many instances, regular maintenance can keep grass from dying.

The best time to aerate a lawn is when there's plenty of moisture in the soil, which is the fall or spring seasons. However, keep in mind that lawn aeration isn't very effective when there has been a long period of heavy rain, as the excess water can potentially damage the lawn in the aeration process. Wait until your lawn is predominantly dry to start the aeration process to ensure best results.

Your St. Augustine grass might look bad due to cold winter months, drought, pest invasion, or lawn disease. The first step is properly identifying the problem. Once you’ve figured out what’s making your grass look bad, you’ll need to employ the correct treatments. These treatments may include:

  • Properly mow your lawn and keep the clippings on the lawn as organic matter.

  • Use healthy irrigation techniques.

  • Use the right amount of fertilizer.

  • Keep up a good, regular maintenance routine.

  • Use fungicides.

Yes—lawn renovation can turn your lawn from damaged to healthy in one month or less. You should also consider lawn renovation an investment in your home’s future. Not only will a lawn renovation ensure that you have a beautiful, healthy, and thriving lawn, but when it comes time to sell your home, the curb appeal will increase your home’s value.
