Patches of grass in a lawn can appear burnt for a number of reasons. Grass that is cut too short, over-fertilised or lacking water often appears brown or burnt. And burnt is not a good look for a lawn. Thankfully for homeowners struggling with sorry-looking lawns, there are a few basic steps that can help to revive the grass and restore it to a brilliant green.

Mow your lawn to height of 2 1/2 inches. If you are mowing it shorter than this, it is likely to turn brown and take on a burnt appearance.

Water the burnt spots and entire lawn with 1 inch of water weekly. If your lawn is littered with burnt spots, it may be caused by lack of water. In especially hot months it is necessary for the soil to be moist approximately 4 to 6 inches down.

Replace permanently damaged burnt spots. In some cases watering the burnt spots or spots that have been cut too short is not enough to revive them. In these cases, dig around the spots and remove the grass and its roots. Aerate the soil with a pitchfork, moisten it with a garden hose, then spread grass seed onto the soil. There should be a dozen grass seeds for every square inch of soil. Water it three times daily for the first week, then daily until it reaches 3 inches in height.


Be sure to use the same grass seed that your lawn is composed of.
