Caring for Your Lawn in Hot and Humid Weather
Has your lawn been enduring long, hot days followed by afternoon storms recently? These extreme conditions can have a significant impact on your lawn. Let’s explore how they affect it and what you can do to help during such weather.

How Can I Prevent Disease in My Lawn?
Hot and humid conditions create an ideal environment for lawn diseases, particularly fungal infections. However, there are steps you can take to prevent them from taking hold.
One effective method is to reduce shade by trimming back surrounding trees and shrubs. This allows for better evaporation, helping your lawn dry out faster and reducing the chances of disease development. Plus, less shade means more sunlight for photosynthesis, supporting your grass’s overall health and growth.
What Time of Day Should I Water My Lawn?
Proper watering techniques are crucial to avoid leaving your lawn damp for too long. On hot days, it’s best to water your lawn early in the morning before the heat sets in. Avoid watering in the afternoon or evening, as this can cause the grass to remain damp overnight, creating a breeding ground for diseases.
Should I Use a Wetting Agent?
To make the most of rainfall or irrigation, using a wetting agent like Lawn Soaker can be very helpful. Wetting agents help water-averse, hydrophobic soils absorb water more efficiently, allowing it to reach the grass roots rather than pooling on the surface. Lawn Soaker comes in a convenient hose-on bottle, making application a breeze.
Why Is Regular Mowing Still Important?
Irregular mowing can lead to weak, sparse grass, which makes your lawn more vulnerable to disease, especially during hot and humid weather. Regular mowing keeps your grass strong and healthy, which is essential for resisting the stresses of extreme weather conditions.
How Often Should I Mow?
As a general guideline, aim to mow your lawn frequently enough to remove no more than one-third of the grass height at each session. This ensures your lawn stays at its healthiest.
How Can Aeration Help in Hot and Humid Weather?
Aeration is the process of improving the flow of air, water, and nutrients in the soil by creating small holes in the ground. This can be done in various ways, but using a garden fork is one of the simplest methods. To aerate, drive the fork into the soil, wiggle it to loosen the ground, and then space your holes about 10 cm apart. Aeration helps your lawn stay healthier by allowing better movement of water and nutrients.
By following these tips, you can help your lawn thrive, even in the heat and humidity of summer.
