Why Is My Grass Dying?
If your lawn is turning brown and dying, there are a number of possible reasons. Here are some of the most common causes and what you can do to fix them:
Drought
Drought is one of the most common reasons for dying grass. When there is not enough water, grass goes dormant and turns brown. If you live in an area that is experiencing a drought, you may need to water your lawn more frequently. However, avoid overwatering, as this can also damage your lawn.
Thatch
Thatch is a layer of dead grass and other organic matter that builds up on the surface of your lawn. Too much thatch can prevent water and nutrients from reaching the roots of your grass, causing it to die. You can reduce thatch by dethatching your lawn with a dethatching rake or power dethatcher.
Improper Mowing
Mowing your lawn too short can stress the grass and cause it to turn brown. As a general rule, you should remove no more than one-third of the height of the grass at each mowing. It is also important to mow your lawn regularly, as allowing it to grow too long can also damage the grass.
Improper Watering
Watering your lawn too frequently or too infrequently can also cause it to turn brown. Water your lawn deeply about once a week, or when the grass looks slightly wilted. Avoid shallow watering, as this can encourage the development of weak roots.
Insects
Insects can also damage your lawn, causing it to turn brown. Some of the most common lawn pests include grubs, chinch bugs, and sod webworms. You can treat insect infestations with insecticides, but it is important to follow the instructions on the product label carefully.
Salt Damage
Salt damage can also cause your lawn to turn brown. This can happen if you live near a street or sidewalk that is treated with salt during the winter months. You can prevent salt damage by flushing your lawn with water after it has been treated with salt.
Pet Spots
If you have a dog, you may notice brown spots on your lawn where your dog has urinated. Dog urine contains nitrogen, which can burn your grass. You can prevent pet spots by training your dog to go to the bathroom in a designated area, or by diluting the urine with water.
Fungus
Fungus can also cause brown spots on your lawn. Some of the most common lawn diseases include brown patch, dollar spot, and leaf spot. You can treat fungus with fungicides, but it is important to follow the instructions on the product label carefully.

- Water your lawn deeply and regularly.
- Fertilize your lawn with a balanced fertilizer.
