What Happens if You Overfertilize the Lawn?

“I love my Father-in-Law,” Duane said. “Especially how he gives me helpful advice all of the time. Like when he noticed how the whole backyard was full of yellow, patchy grass and said I needed to stop letting the dog pee everywhere? Fantastic, Dad, but we don’t have a dog.”

Brown & Yellow Grass Could be a Sign of Overfertilization

While pet urine can definitely be hard on your lawn, when you don’t have a dog, you can’t blame Fido for your brown and yellow grass. Another likely cause? Too much fertilizer.

Fertilizer is like food for your lawn. And like food, you can have way too much of a good thing. If you ate nine cheesecakes at a time, you wouldn’t be looking or feeling your best. The same is true for your lawn. Too much fertilizer at once damages the grass. The grass turns yellow and brown because it’s being burned by excessive contact with the minerals and nutrients that are supposed to sink down to the root system. When a lawn has been over fertilized, you can sometimes observe excess fertilizer remaining on the surface of the soil.

Just because your lawn is overfertilized doesn’t mean you put too much fertilizer on your lawn. Sometimes the issue is drainage. When water moves across your yard, it can move fertilizer from one area to another, accumulating too much in one area and causing damage. Sometimes the overfertilization is a result of how the fertilizer is formulated. Remember, if the fertilizer isn’t specifically mixed for your lawn’s microclimate, it might not be right for your lawn.
