How to Treat and Prevent Fertilizer Burn
Fertilizer burn can be a common yet frustrating issue for gardeners and homeowners who take pride in their lawns and gardens. This phenomenon occurs when too much fertilizer is applied to the plant, causing the roots to get damaged due to high salt concentrations. The result is often yellowed, scorched-looking foliage and stunted growth. However, with the right knowledge and techniques, you can both treat and prevent this unsightly problem.
Understanding Fertilizer Burn
Fertilizer burn happens when plants receive more nutrients than they can absorb. The excess fertilizer alters the water concentration in the soil, leading to dehydration of plant roots and foliage. Symptoms include:
- Browned or yellowed leaf edges
- Wilted plants
- Stunted growth or death of plants
How to Treat Fertilizer Burn
If you suspect your plants are suffering from fertilizer burn, follow these steps to help them recover:
1. Water Your Plants Thoroughly
- Immediately water the affected area deeply. This helps to flush out the excess fertilizer from around the root zone. Continue to water daily for about a week to aid recovery.
2. Remove Damaged Foliage
- Trim away severely damaged or dead leaves and stems. This helps the plant focus its energy on producing new, healthy growth.
3. Apply a Layer of Mulch
- Adding organic mulch around the base of the plant can help retain soil moisture and protect the roots.
4. Monitor Plant Recovery
- Keep an eye on the plant over the following weeks. It may take time for it to fully recover.
Preventing Fertilizer Burn
Prevention is always better than cure. Here are some tips to prevent fertilizer burn in the future:
1. Follow Fertilizer Instructions Carefully
- Always read and follow the instructions on the fertilizer package. Applying too much fertilizer is a common cause of fertilizer burn.
2. Choose the Right Type of Fertilizer
- Opt for a slow-release or controlled-release fertilizer. These types spread their nutrients over a longer period, reducing the risk of burn.
3. Test Soil Regularly
- Conduct soil tests to understand the nutrient needs of your plants. This prevents over-fertilization.
4. Water Before and After Fertilizing
- Water your plants one day before applying fertilizer to prepare the soil. Water again lightly after applying to help dissolve the fertilizer and reduce salt concentration.
5. Apply During Suitable Weather
- Avoid fertilizing during extremely hot and dry conditions. High temperatures can increase the risk of fertilizer burn.

Dealing with fertilizer burn can be disheartening, but with proper care and preventive measures, you can keep your garden lush and healthy. Remember, the key is to understand the specific needs of your plants and soil.
