How to Fix Fertilizer Burn on Lawn
A Step-by-Step Guide to Reviving Your Lawn
Fertilizer burn occurs when excessive fertilizer is applied to the lawn, causing grass to turn brown and die. If you notice patches of scorched grass, it's crucial to act quickly to mitigate damage and restore your lawn's health. This guide will walk you through the steps to fix fertilizer burn and prevent it from happening in the future. To effectively fix fertilizer burn on your lawn, start by assessing the damage. Identify the affected areas and determine the type of fertilizer used. The next steps involve watering the lawn, applying a soil amendment, and possibly reseeding the damaged areas. By following these steps, you can revive your lawn and promote healthy growth.
Understanding Fertilizer Burn
Fertilizer burn happens when too much fertilizer is applied, leading to high salt concentrations in the soil. This can dehydrate grass roots, resulting in brown patches. Common signs of fertilizer burn include:
- Brown or yellow patches on the lawn
- Grass that feels crispy or dry
- Visible salt crust on the soil surface
How to Fix Fertilizer Burn on Lawn
Here’s a step-by-step guide to help you fix fertilizer burn:
- Assess the Damage: Walk around your lawn and identify the areas affected by fertilizer burn. Take note of the severity of the damage.
- Water the Affected Areas: Immediately water the burned areas deeply. This helps dilute the salts in the soil. Aim for at least 1-2 inches of water over the next few days.
- Apply a Soil Amendment: Consider applying gypsum to help break down salts in the soil. Follow the package instructions for the correct application rate.
- Reseed if Necessary: For severely damaged areas, you may need to reseed. Choose a grass seed that matches your existing lawn. Prepare the soil, sow the seeds, and keep them moist until germination.
- Monitor and Maintain: Continue to water the lawn regularly and avoid fertilizing until the grass shows signs of recovery.
Tools and Materials Needed
- Garden hose or sprinkler
- Gypsum or other soil amendments
- Grass seed (if reseeding)
- Rake and shovel (for reseeding)
