    When it comes to watering the garden, it isn’t just a matter of splashing a garden hose around and calling it a day. During a heatwave, using water irresponsibility is not only bad for the environment, but can lead to problems with your water pressure.

    During the dry weather in May, Water UK saw a huge surge in demand for water in the evenings, 40 per cent higher than normal for the time of year. The demand let to reductions in water pressures in some areas of the UK.

    Janet Manning, RHS water management specialist, has shared her tips for how to conserve water when watering your garden during a heat wave.

    1. Don’t water your lawn

    During dry spells when the grass is starting to look a bit crispy and brown it can be tempting to give it a good water. However, you’d be better of saving the water.

    ‘Lawns are tough, and you may be surprised at how quickly they bounce back after rainfall,’ explains Janet.

    2. Install a water butt

    These are great for collecting rainwater for watering the plants. ‘Keep an eye on the weather forecast, and with potential rain approaching, install water butts or clean out your existing water butts ready to collect the rain,’ advises Janet.

    3. Switch to watering in the morning

    Domestic water use usually peaks in the early evening. Watering in the morning will ease the demand later in the day.

    ‘This will also help provide the water that plants will draw on through the day, and will avoid it just draining away at night,’ says Janet.

    4. Swap a hose for a watering can

    Hoses use an incredible amount of water. One hour’s use is equal to the average water supply for a family of four for two days.

    Using a bucket or watering can will help control the amont of water used. The slower water flow will also mean more water will stay in the pot, than running out the bottom.

    5. Train your plants to use water more slowly

    ‘Using less water will actually encourage the plants to drink less,’ says Janet. ‘In essence, if you keep the glass half full, your plants will adapt and learn to drink more slowly.’

    ‘We all want to enjoy our gardens and keep our plants healthy. But as we look forward to another period of sunny weather, it’s good for us all to be aware of the water we’re using and work together to use it wisely,’ says Water UK chief executive Christine McGourty.
