Too Much Fertilizer on Grass: The #1 Mistake to Avoid

What Happens When You Over-Fertilize Your Lawn?

Fertilizing your lawn is essential for keeping it healthy and green. However, it's important to avoid using too much fertilizer, as this can actually damage your grass and the environment.

1. Fertilizer Burn

One of the most common problems associated with over-fertilizing is fertilizer burn. This occurs when the fertilizer salts build up in the soil and damage the grass roots. Symptoms of fertilizer burn include:

• Brown or yellow patches on the grass
• Stunted growth
• Wilted leaves
• Dry, brittle grass

2. Nutrient Imbalances

Over-fertilizing can also lead to nutrient imbalances in the soil. This can prevent your grass from getting the nutrients it needs to thrive. Symptoms of nutrient imbalances include:

• Yellowing or pale green grass
• Poor growth
• Thinning grass
• Increased susceptibility to pests and diseases

3. Environmental Damage

Over-fertilizing can also have a negative impact on the environment. When fertilizer runs off into waterways, it can cause algal blooms and other water quality problems. Fertilizer can also contribute to air pollution.

How to Avoid Over-Fertilizing

The best way to avoid over-fertilizing your lawn is to follow the instructions on the fertilizer label. The label will tell you how much fertilizer to use and how often to apply it.

Here are some additional tips for avoiding over-fertilizing:

• Use a slow-release fertilizer. Slow-release fertilizers release their nutrients over a period of time, which helps to prevent fertilizer burn.
• Water your lawn deeply after fertilizing. This will help to move the fertilizer down into the soil and prevent it from running off.
• Avoid fertilizing during hot, dry weather. Fertilizer can burn grass more easily when the weather is hot and dry.

How to Fix Over-Fertilized Lawn

If you think you have over-fertilized your lawn, the best thing to do is to water it deeply and frequently. This will help to flush the fertilizer salts out of the soil. You may also want to aerate your lawn to help improve drainage.

In severe cases, you may need to reseed your lawn.
