The Midlands, like much of the UK, can experience unpredictable weather, and heatwaves are not uncommon. When the rain stops and the sun beats down, our lawns can take a hit. But don't worry, with the right steps, you can bring your lawn back to life.

Quick Answer

To recover your lawn from drought stress, start by deep watering regularly, avoid mowing too low, and apply a balanced fertiliser. These steps will help your lawn revive.

Understanding Drought Stress

Drought stress occurs when your lawn doesn't get enough water, leading to brown, dry patches. This usually happens during prolonged periods of heat and little rain, which is quite typical in some UK summers.

Steps to Revive Your Lawn

1. Watering Correctly

Watering is the most crucial step. During dry spells, water your lawn deeply once or twice a week. Aim for about 1-1.5 inches of water each time, which is roughly equivalent to 2.5-3.8 cm. Early morning is the best time to water, as it reduces evaporation.

2. Adjusting Your Mowing Habits

Keep your mower blades high, around 3-4 cm, to help shade the soil and reduce water loss. Avoid mowing during the hottest parts of the day, and never remove more than a third of the grass height at a time.

3. Fertilising

Use a balanced fertiliser to promote healthy growth. Avoid fertilisers high in nitrogen during a drought as they can stress the lawn further. Instead, look for a slow-release fertiliser that provides essential nutrients gradually.

4. Aeration

If your lawn is compacted, consider aerating it to allow water and nutrients to penetrate more effectively. This is especially useful in clay-heavy soils common in the Midlands.
