Reviving your grass after a scorching summer is a common concern for many homeowners. There are many important points we need to cover here, but it’s generally a good idea to start by giving your lawn a good, deep watering.
Aim for about 1 to 1.5 inches of water per week, either through rainfall or irrigation. Water early in the morning to minimize evaporation and allow the grass to dry before evening, reducing the risk of fungal diseases.
If your soil is compacted, consider aerating your lawn. Aerating helps improve soil structure and allows water, air, and nutrients to penetrate deeply to the roots. This can invigorate your grass. As an added precaution, especially if your lawn has a thatch problem (a thick layer of dead grass and roots), consider dethatching in early fall. This allows water and nutrients to reach the roots more effectively.
For lawns with bare patches or thin areas, overseeding is also a smart move. Choose a grass seed blend suitable for your region and lawn type. Spread the seeds evenly over the lawn and keep the area consistently moist until the new grass establishes itself.
For best results on how to make grass green, apply a balanced, slow-release fertilizer with a slightly higher ratio of nitrogen (the first number in the N-P-K ratio). However, avoid fertilizing during periods of extreme heat. Wait for cooler weather or early fall for the best results.
Finally, make sure to adjust your mower to leave your grass around 2.5 to 3 inches tall. Taller grass shades the soil, reduces evaporation, and promotes deeper root growth. Be sure to avoid cutting more than one-third of the grass blade at a time.
