The recent heatwave has left many lawns across Staffordshire and the Midlands looking worse for wear. Thankfully, with a bit of care and attention, you can bring your lawn back to life.
Quick Answer
To recover your lawn from fusarium after a heatwave, aerate the soil, apply a balanced fertiliser, and ensure adequate watering. Regular monitoring and maintenance will help prevent future outbreaks.
Understanding Lawn Fusarium
Fusarium patch, also known as snow mould, thrives in cool, wet conditions but can strike after a heatwave when the lawn is stressed. This fungal disease appears as yellow or brown patches, often with a white or pinkish mould on the grass.
Steps to Recovery
1. Aerate the Lawn
Aerating your lawn helps improve air circulation and allows nutrients to penetrate the soil. You can use a garden fork, inserting it about 10-15 cm apart, or hire a mechanical aerator for larger areas.
2. Apply Fertiliser
Use a balanced fertiliser to provide essential nutrients. A fertiliser with a 10-10-10 ratio (nitrogen, phosphorus, potassium) is ideal. Apply it evenly and water in thoroughly to avoid burning the grass.
3. Water Appropriately
Ensure your lawn receives about 2.5 cm of water weekly. Early morning is the best time to water, reducing the risk of disease by allowing the grass to dry during the day.
Monitoring and Maintenance
- Regularly check for signs of fusarium, especially after wet conditions.
- Mow your lawn at the correct height to avoid stress on the grass.
- Remove any thatch build-up to improve water and nutrient absorption.

Frequently Asked Questions
What causes fusarium patch to appear?
Fusarium patch often develops in cool, damp conditions, but lawns stressed by heatwaves are also susceptible, particularly if they are poorly drained or nutrient-deficient.
How often should I aerate my lawn?
For most lawns, aerating once a year in the spring or autumn is sufficient. However, if your lawn is heavily compacted, consider aerating twice a year.
Can I use fungicides to treat fusarium?
Fungicides can be effective, but they should be a last resort. Focus on improving lawn health through cultural practices and consult a professional if the problem persists.
