The expert said: “You should mow the lawn frequently during August, but remember to raise the cutting height.
“Grass sends its roots further down into the ground when left to grow longer, making it more drought-tolerant and less likely to turn brown during heat waves.
“Too much trimming when dry can cause damage and can actually make your grass more susceptible to disease.”
Longer grass blades also enhance photosynthesis, promoting stronger growth and suppressing weeds.
For a general-use lawn, maintain a mowing height of 2.5cm to 4cm; a shorter cut is recommended for fine lawns.
To prevent stress, it’s important to avoid removing more than one-third of the grass blade length at a time.
Consider sharpening your mower blades, too, if you’re not achieving a clean cut.
Other ways to help the lawn stay green in August include fertilising it with a summer feed and then switching to an autumn fertiliser from September onwards.
It’s recommended that it be fed every six to eight weeks, but follow the manufacturer’s instructions, as this can differ between feeds.
