Can Overwatering Kill Your Grass? What You Need to Know

Since water and sunlight are two essentials you need if your lawn is to have green, healthy grass, most lawn owners believe that the more they water their lawn, the greener the grass will be. However, this is not the case.

Can overwatering kill grass? This post will tell you everything you need to know about what overwatering can do to your grass and how the professional Chappaqua lawn care we offer can help.

Can Overwatering Kill Grass?

No one wants a lawn full of brown patches. While watering your lawn can help you avoid this, too much of anything is poisonous.

Your lawn’s soil consists of soil particles surrounded by pockets of water and air that provide the roots of your grass with everything they need to survive. When you overwater your lawn, you fill all these pockets with water and remove the oxygen, causing the grass roots to suffocate.

On top of that, you also risk stunting the roots. This is because when water is readily available, there is no incentive for the roots to grow deeper. When this happens, your lawn’s root system does not develop, resulting in a shallow system susceptible to disease and drought.

How to Know You Are Overwatering Your Grass

The good news is that your lawn will always offer you signs that help you determine whether you are overwatering your grass. The following are some of those signs.

Spongy Lawn

This is one of the simplest ways to tell if you are overwatering your lawn. All you need to do is step on the different areas of your yard. If they feel squishy or spongy, or if you see patches of standing water, you are probably overdoing it.


When there are streams of water running off the lawn, it means that no more water can make its way into the soil because it is well saturated. Besides being wasteful, runoffs also wash away nutrients that are essential to your lawn’s entire health.

Excessive Weeds

While overwatering can kill grass, it does wonders for the growth of weeds like yellow nutsedge and smooth crabgrass. Therefore, should you notice the presence of excessive weeds, it might be time to scale back on the watering.

Excessive Thatch

Thatch is a layer of partly decomposed plant material that organisms often break down to provide the soil with natural nutrients.

When you overwater your lawn, you prevent these organisms from breaking the thatch down. This causes a build-up of thatch and prevents oxygen from getting into the soil. On top of that, the thatch will provide bugs with the perfect place to hide, protecting them from predators, sun, and pesticides.

The Growth of Fungi

Have you noticed any discoloration on your lawn, especially on the grass blades? You have likely overwatered your lawn so much that you have created ideal conditions for fungal growth. Besides this discoloration, the presence of mushrooms all across your yard is another clear indicator.
