If you’re a homeowner who takes pride in maintaining their lawn, discovering that your green grass is turning yellow and dying can be frustrating and concerning. Not only does it detract from the aesthetic appeal of your outdoor space, but it may also be an indication of an underlying problem that needs attention. In this comprehensive guide, we will explore some possible reasons why your grass might be turning yellow and dying, along with some tips on how to fix the problem.

Environmental Factors

Many environmental factors can contribute to the yellowing and dying of your lawn. Some of the most common culprits include:


A lack of rainfall or regular watering can cause grass to turn yellow and ultimately die. This is because grass requires a lot of water to stay healthy and green. If you’ve noticed that your grass is turning yellow and it’s been a while since it’s rained, it’s likely that your lawn is simply thirsty.

Heat Stress

Exposure to extreme heat can also cause grass to turn yellow and die. If your lawn is in direct sunlight for prolonged periods, it may not be getting enough shade to protect it from the sun’s harmful rays. This can cause the grass to dry out, turn yellow, and eventually die.


While fertilizing your lawn is an essential step in keeping it healthy, using too much fertilizer can be harmful. Over-fertilizing can burn the roots of the grass, causing it to turn yellow and die.

Pests and Diseases

Another reason why your grass might be turning yellow and dying is because of pests or diseases. Common culprits include:


Grubs are the larvae of beetles, and they can be destructive to your lawn. If you notice that your grass is turning yellow and feels spongy when you walk on it, it’s possible that grubs are present. These pests feed on the roots of the grass, causing it to die.

Fungal Infections

Fungal infections can also cause grass to turn yellow and die. Diseases like brown patch or dollar spot can be especially damaging to your lawn. These infections are often caused by stagnant water or over-watering, which can create the perfect environment for fungi to thrive.

How to Fix Yellowing Grass

If you’ve noticed that your grass is turning yellow and dying, there are a few steps you can take to remedy the situation:


If your lawn is suffering from drought or heat stress, the first step is to make sure it’s getting enough water. A general rule of thumb is to water your lawn one to two inches per week. However, if you live in an area experiencing extreme heat or drought, you may need to water your lawn more often.


If your grass is turning yellow due to nutrient deficiency, fertilizing may be the solution. Be sure to follow the instructions on the fertilizer carefully and avoid over-fertilizing, which can cause more harm than good.

Pest Control

If pests or diseases are the cause of your lawn’s yellowing, there are various treatments available. Consult with a lawn care specialist to determine the right course of action for your specific situation.


A yellowing and dying lawn is a common problem that can be caused by a variety of factors. It’s essential to identify the underlying cause so that you can take the necessary steps to fix it. Proper watering, fertilizing, and pest control can all go a long way in restoring your lawn’s health and beauty.

FAQs About Why Grass Turns Yellow and Dies

Q: Can cutting grass too short cause it to turn yellow?

A: Yes, cutting your grass too short can cause it to turn yellow. This is because it doesn’t have enough blade surface area to absorb sunlight and produce chlorophyll, which gives the grass its green color.

Q: Should I water my lawn in the morning or evening?

A: It’s best to water your lawn in the morning. This allows the grass to absorb the water before the heat of the day sets in, which reduces the risk of evaporation. Watering in the evening can lead to fungal infections since the grass remains wet for an extended period.

Q: How do I know if my lawn has a fungal infection?

A: If you notice circular patches of yellow or brown grass, it’s possible that your lawn has a fungal infection. Additionally, if the grass feels slimy or spongy to the touch, this is another indication of a fungal infection.
