How to Fix an Over Fertilized Lawn


Having a lush and healthy lawn is the dream of every homeowner. However, sometimes our enthusiasm for fertilizing can lead to overdoing it, resulting in an over fertilized lawn. This can cause damage to the grass, leaving it weak and vulnerable to diseases and pests. In this article, we will provide you with some tips on how to fix an over fertilized lawn and restore it to its former glory.

What are the signs of an over fertilized lawn?

Before we delve into the solutions, it’s important to identify the signs of an over fertilized lawn. These signs include yellowing or browning of the grass, stunted growth, excessive thatch buildup, and an increase in weeds. If you notice any of these symptoms, it’s likely that your lawn has been over fertilized.

1. Water the lawn thoroughly

The first step in fixing an over fertilized lawn is to water it thoroughly. This will help to flush out the excess fertilizer from the soil. Water the lawn deeply, allowing the water to penetrate the soil and wash away the excess nutrients. Repeat this process a few times over the course of a week to ensure all the excess fertilizer is removed.

2. Aerate the soil

After watering, it’s important to aerate the soil to improve its drainage and allow air to reach the grass roots. You can use a garden fork or a mechanical aerator to create small holes in the soil. This will help the excess fertilizer to leach out and prevent further damage to the grass.

3. Apply activated charcoal

Activated charcoal is an excellent remedy for an over fertilized lawn. It helps to absorb the excess nutrients and toxins from the soil, allowing the grass to recover. Sprinkle a thin layer of activated charcoal over the affected areas and water it in. Repeat this process every few weeks until the lawn starts to show signs of improvement.

4. Test the soil

To prevent future over fertilization, it’s important to test the soil before applying any fertilizers. A soil test will determine the nutrient levels in the soil and help you choose the right type and amount of fertilizer for your lawn. You can purchase a soil testing kit from a garden center or consult a professional for accurate results.

5. Use organic fertilizers

When it comes to fertilizing your lawn, it’s best to opt for organic fertilizers. These are slow-release fertilizers that provide a steady supply of nutrients to the grass without the risk of overdoing it. Organic fertilizers also improve the soil structure and promote the growth of beneficial microorganisms, which in turn enhances the overall health of your lawn.

6. Avoid excessive fertilization

One of the main causes of an over fertilized lawn is excessive fertilization. It’s important to follow the recommended dosage instructions on the fertilizer packaging and avoid applying more than necessary. Remember, more is not always better when it comes to fertilizing your lawn.


Fixing an over fertilized lawn requires patience and proper care. By following the steps outlined in this article, you can restore your lawn to its former glory and ensure its long-term health. Remember to water the lawn thoroughly, aerate the soil, apply activated charcoal, test the soil, use organic fertilizers, and avoid excessive fertilization. With these tips, your lawn will be back to being healthy and vibrant in no time.
