9. Swap your hose for a watering can
Much as showers can quickly use more water than we realise, a hosepipe can pump out around 1,000 litres of water an hour. So consider watering your garden with a watering can instead.
In addition, mulching your plants (with bark chippings, heavy compost or straw) and watering in the early morning or late afternoon will reduce evaporation, saving water.
