Hi there, We're the Hedge Cutting Staffordshire team, your local gardening expert from Staffordshire. Yellow patches in your lawn can be frustrating, but don’t worry—I'm here to help you identify the causes and offer some practical solutions.

Quick Answer

Yellow patches are often caused by improper watering, nutrient deficiencies, pests, or diseases. Address these by adjusting your care routine and treating any underlying issues.

Common Causes of Yellow Patches

1. Watering Issues

One of the most common causes of yellow patches is incorrect watering. Lawns in the Midlands typically need about 2.5 cm of water a week, including rainfall. Under-watering or over-watering can both stress your grass.

  • Ensure even watering across the entire lawn
  • Avoid watering in the heat of the day to reduce evaporation
  • Use a rain gauge to track rainfall and adjust watering accordingly

2. Nutrient Deficiencies

Your lawn might be suffering from a lack of essential nutrients, particularly nitrogen. A simple soil test can help determine what nutrients are missing.

Month Recommended Fertiliser Application Rate
April Nitrogen-rich fertiliser 35 g/m²
September Balanced fertiliser 30 g/m²

3. Pests and Diseases

Insects like chafer grubs and diseases such as red thread can cause yellow patches. Regularly inspect your lawn for signs of pests or unusual growth patterns.

  • Identify pests by digging up small patches of turf
  • Apply appropriate pest control measures if needed
  • Maintain good lawn hygiene to prevent disease

Fixing Yellow Patches

Adjust Your Watering Routine

Establish a consistent watering schedule. In the Midlands, early morning is the best time to water your lawn to maximise absorption and minimise evaporation.

Fertilising Your Lawn

Apply the right type of fertiliser at the correct times of the year. Follow the table above for guidance tailored to our local conditions in Staffordshire.

Dealing with Pests

If pests are the issue, consider natural remedies or targeted chemical treatments. Always follow label instructions to protect beneficial insects and the environment.
