Excessive Fertilizer

4 Steps to Reviving St. Augustine Grass

There are a few ways to restore your ailing grass to its prior grandeur. They include things like increasing soil quality, dethatching, and correctly fertilizing.

1. Give It Space

This is an important first step: do not disrupt your lawn by playing on it, driving on it, or allowing your canine to defecate on it. St. Augustine vegetation is strained and delicate, and this action will only aggravate it.

2. Improve The Soil

If the earth isn’t favorable to good development, St. Augustine vegetation can perish. Here’s how to improve your dirt condition.

  • Perform a soil test:  Begin your changes by conducting a dirt test. You can buy a do-it-yourself package and submit it to an institution or facility for examination. Knowing what makeup and minerals your earth requires will help your vegetation thrive.
  • Dethatching Too much thatch buildup can be harmful to your St. Augustine vegetation; anything over 12 inches can cause problems. Thatch is a decaying coating of organic matter, such as grass buds and stalks, that accumulates between the earth and your lawn’s grass blades. It can suffocate your grass by restricting its access to required nutrients, oxygen, and water. Rent or purchase a dethatching brush to split up this dirt and increase the aeration of your soil.

3. Water The Grass

Proper irrigation methods go a long way, particularly in the summer temperatures. While it is generally recommended to give your grass 1-1.5 inches of water per week in one of two waterings, consider giving your lawn the same amount of water in three distinct waterings during the summer. Make sure the water soaks down to a depth of about 6 inches in the earth.

You can put this to the test by inserting a screwdriver into the earth and observing how readily it moves. More water is required if you encounter a lot of opposition.

4. Be Careful Mowing

Make sure your grass machine is set to the highest or second highest level. This will enable your lawn to grow upright, enabling it to develop deep, powerful roots and fight more effectively with pests. .
