Gardening experts in the UK recommend against watering lawns that have turned brown during the current heatwave, as many grass species naturally go dormant in drought conditions. They advise saving water for essential use and suggest that lawns will recover once rainfall returns.
- 01Ceri Thomas, editor of Which? Gardening, states that most UK lawns consist of hardy grasses that go dormant during droughts.
- 02Brown grass is typically a temporary condition and lawns can recover quickly with rainfall.
- 03Light, frequent watering can lead to shallow root growth, which is less drought-tolerant.
- 04The Royal Horticultural Society advises watering only if absolutely necessary, as established lawn roots remain alive.
- 05For new lawns, using grey water or stored rainwater is recommended over mains water.

As gardeners take advantage of the ongoing heatwave, experts are warning against watering brown lawns, which is often unnecessary. Ceri Thomas, the editor of Which? Gardening, explains that many grass species in the UK enter a dormant state during dry spells to conserve energy. Although brown grass may appear alarming, it is typically a temporary condition, and lawns can recover quickly once rain returns. Frequent light watering is discouraged as it encourages shallow root systems, which are less resilient to drought. The Royal Horticultural Society supports this view, suggesting that established lawn roots remain alive and capable of recovery. They recommend watering only when absolutely necessary, and if needed, using grey water or stored rainwater for new lawns. Additionally, gardeners are advised to focus on other plant care during the heat, with certain plants like hydrangeas and Japanese maples requiring more attention, while drought-resistant varieties such as lavender and rosemary are better suited for the conditions.
