What Causes Black Patches On Your Lawn After Fertilizing?

A lush, green lawn is the pride of many homeowners. But sometimes, after fertilizing, your lawn will develop black patches. It’s frustrating, but what causes it? Before you can address the issue, you need to know what’s causing it.

Fungal Disease

Fungal diseases are one of the most common causes of black patches on your lawn after fertilizing. Fungal diseases, such as red thread or dollar spot, can quickly take hold on your lawn if conditions are right. High humidity and wet conditions can cause fungal diseases to spread quickly.

When you fertilize your lawn, it can create an environment that encourages fungal disease to take hold. Fertilizer can create high levels of nitrogen, which can, in turn, lead to lush, thick growth. This thick growth can create a humid microclimate that can encourage fungal diseases to spread.

Compacted Soil

Compacted soil can also cause black patches on your lawn after fertilizing. Compacted soil can’t absorb water or fertilizer, so the nutrients that you put down won’t be taken up by your lawn. As a result, the fertilizer can create spots of dead, blackened grass.

Compacted soil can be caused by a number of things, including mowing too often, excessive foot traffic, or heavy equipment. To address the issue, you’ll need to aerate your lawn. This will help to break up the compacted soil and allow the roots of your grass to take up the nutrients.

Lack of Water

A lack of water can also cause black patches on your lawn after fertilizing. Fertilizer is only useful when it’s combined with water. If you don’t water your lawn regularly, the fertilizer won’t be taken up by the grass and you’ll end up with patches of dead, blackened grass.

To prevent this, you should water your lawn regularly. This will help the fertilizer to be taken up by the roots of your grass and help your lawn to stay green and healthy.

Conclusion

Black patches on your lawn after fertilizing can be caused by a number of things. Fungal diseases, compacted soil, and a lack of water can all contribute to the issue. To address the issue, you’ll need to identify the cause and take steps to remedy it. With proper care, you can keep your lawn looking its best.
