One of the most common problems after a dry spell is dollar spot, a fungal disease that can leave your lawn looking patchy and unattractive. Fortunately, with the right approach, you can restore your lawn to its former glory. Let’s delve into how you can tackle dollar spot effectively in the UK climate.
Quick Answer
To recover from dollar spot after drought, ensure consistent watering, improve soil aeration, and apply a balanced fertiliser. Regular mowing and dethatching are also key.
Understanding Dollar Spot
Dollar spot is a fungal disease caused by Sclerotinia homoeocarpa, often appearing as small, straw-coloured patches on your lawn. After a drought, your grass is more susceptible due to weakened roots and reduced vigour. It thrives in humid conditions, often following dry spells when watering resumes.
Steps to Recovery
1. Watering Wisely
Post-drought, it's crucial to re-establish a consistent watering schedule. In the Midlands, this usually means aiming for about 2.5 cm of water per week, ideally delivered in the early morning to reduce evaporation.
- Water deeply but less frequently to encourage deep root growth.
- Avoid evening watering to reduce humidity overnight.
- Use a rain gauge to track weekly rainfall and adjust watering as needed.
2. Aeration and Soil Health
Improving soil aeration is vital after a drought. Compacted soil can exacerbate lawn diseases, so consider aerating your lawn in early autumn. This helps improve air circulation and root growth.
| Month | Task | Notes |
|---|---|---|
| September | Aeration | Use a hollow tine aerator for best results |
| October | Fertilising | Apply a balanced autumn fertiliser |
3. Fertilising for Recovery
Post-drought, your lawn will benefit from a balanced fertiliser, ideally in early autumn. This helps replenish nutrients and support grass recovery. Look for a mix that contains nitrogen, phosphorus, and potassium.
4. Mowing and Dethatching
Regular mowing keeps your lawn healthy, but avoid cutting too short. Set your mower blade to the highest setting to allow grass to photosynthesise effectively. Dethatching in late summer can also help remove dead grass and improve air circulation.
