Grass Turning Yellow after Fertilizing | Lawn Care Tips

In this article, we explore the causes of this phenomenon and we also provide solutions for how to fix it.

Too much or too little fertilizer can cause burnt patches on lawns. Quick-release fertilizers release more fertilizer in a shorter span of time, which means that areas spend less time receiving these nutrients. This can cause burnt patches on your lawn.

If you’ve ever seen the brown patches on your lawn, you know that grass turns yellow after it’s been fertilized. But what exactly is going on?

How You Keep grass green after fertilizing

Fertilizing your lawn isn’t a bad idea. It can help the lawn stay green and healthy throughout the year, but it’s important to know the proper methods so that you don’t do any more harm than good. In this article, we’ll be discussing different ways to keep your lawn green after fertilizing.

1. How long will my lawn stay green?

This is a question that is often asked. The answer to this question comes down to the fertilizer used. Certain fertilizers, such as manure, can leave an odor that will make the grass smell like urine.

However, if you use slow-release fertilizers, the lawn will stay green for a much longer period of time.

2. How to keep grass green after fertilization

One way to keep the grass green after you have applied fertilizer is to water it. After the fertilizer has been applied, it is important for you to water your garden every day by using a hose or sprinkler.

You will need to take care of your plants as soon as possible so that they can continue cropping up.

3. Why you should use a top dressing

A top dressing is a layer of organic material that is placed on the soil to increase soil quality, improve overall plant health, and retain moisture.

Top dressings can be as simple as decaying leaves or compost and they need to be deep enough to reach the root zone when you are using herbicides.

4. Maintain a lush lawn

Lawns need fertilizer to grow and stay green. However, over-fertilizing can lead to a fungus disease called brown patches.

To prevent this, make sure you spread the fertilizer evenly around your yard. You can also water it heavily after spreading the fertilizer.

5. Crop rotation

Crop rotation is the practice of rotating your crops each season. By rotating, you avoid overusing a certain part of the garden and prevent harmful bugs from building up in the same area.

You can rotate crops by planting them near each other, plant flowers or trees that will eventually shade out the weeds or use compost to enhance fertility.

Grass turning yellow after fertilizing

What Causes Grass Turn Yellow? Grass turns yellow after fertilizing because the nutrients in the bad fertilizer stop working.

The fertilizer has a chemical that turns it into plant food, but when the plant absorbs all of those nutrients, they no longer work and it’s what causes grass to turn yellow.


Grass turns green with fertilizer, but as soon as it rains, it loses its color and starts to yellow. This happens because the fertilizer washes away plant pigments, which plants convert into substances that cause yellowing after getting washed away.
