Why is Your Lawn Going Brown?

Watching your lawn turn brown is not fun. After all the hard work and professional lawn care you put into trimming it, watering it and maintaining it, seeing all of your efforts seemingly go to waste can be disappointing. However, just because your yard is going brown does not mean that you can’t encourage healthy lawn tips now.

Lawns turn brown when the soil doesn’t have enough nutrients or water, or when the roots can no longer get water or nutrients from the soil. The key to getting you beautiful, green lawn back is to figure out the why. Once you know the reason you can treat the specific cause, and get your lawn back to normal. Here are the biggest culprits that might be making your lawn turn brown:

Extreme Heat and Drought

Many types of grass turn dormant in periods of drought and extreme heat. To determine if this is the cause of your grass changing color, look around your yard for any prematurely dropped leaves from trees that are folded up. This can tell you if the drought or heat is affecting the plant life in your yard because trees usually cannot sustain leaves when the temperatures are too high or they don’t have enough water.

Most of the time, you will just need to wait out the weather if that is the issue. To help your lawn with a drought, you will have to give it some extra love. Every two to three weeks during the drought, apply a ½ inch layer of water to your lawn. You can even make your lawn green faster by applying an inch of water every week – or leave the sprinklers on for 2 hours. Check with your city for watering restrictions, however, as many cities put them in place during droughts. Waiting until temperatures drop and regular rain resumes is the best way to get your lawn green again.

Poorly Adjusted Sprinklers

The reason why your lawn could be going brown is because your sprinklers are not adjusted properly, so they are not spraying water on your lawn. If your lawn has dry or brown patches, check to make sure that your sprinklers are reaching all areas.

If you notice that your sprinkler adjustments are not optimized to reach all areas of your lawn, you can easily adjust them with a screwdriver. Oscillating sprinklers are harder to adjust that low-to-the-ground pulsating sprinklers, though.


You might notice that there are a lot of weeds in your yard as your lawn is turning brown. In competition with the grass for water and nutrients, weeds usually win, unfortunately. To help combat the weeds before they arrive, you can apply a pre-emergent herbicide in the spring. This will help prevent the weed seeds from germinating and spreading.

It can be tricky to control weeds on your own, so keep in mind that a professional lawn care service will provide invaluable help with this problem. Sometimes, it’s better to refer to these experts to take care of weeds in your yard because of their tricky nature.


There are many different types of diseases and fungi that can cause your lawn to turn brown. If you notice your lawn covered in black, white or brown substances, that’s a pretty good sign that your lawn is suffering from some type of disease or fungus.

This is something that a lawn care service should take a look at. If you are not well-versed in the types of diseases or fungi that can infect grass, it can be hard to know how to treat it. After a specialist has taken care of the problem and your lawn is healthy again, make sure to follow up with proper care: enough water in the morning, regular mowing and good lawn aeration.
