Always water your plants in the cool of the evening or very early in the morning, rather than during the day, when most of the water would evaporate before getting to the plant roots.

Step 2

Apply water to the base of plants where it can soak down to the roots. In hot weather, give each plant a good soak at two or three day intervals, rather than a quick sprinkle every day.

Step 3

Help channel water to the roots of thirsty plants, like this tomato (see picture), by burying a flowerpot alongside it. This can be filled with water where it will soak down into the soil.

Micro-drip irrigation systems can be installed to deliver water directly to where the plants can use it. Applied slowly, water gradually soaks to the roots, rather than running off or evaporating. It will save you time and reduce the amount of water that’s wasted.

Step 5

Store as much rainfall as you can in water butts collected from the roof of your house, garage, shed and greenhouse. This will be warmer and thus cause less of a shock to plant roots than mains water.

Step 6

Use waste water from preparing vegetables and washing up as well as that from baths and showers. Don’t use water that contains bleach or powerful household cleaning products, which could damage plants.

Step 7

Water-retaining granules can be added to the compost when planting bedding in pots, hanging baskets and other containers. The roots of the plants grow around the saturated granules to draw moisture as they need it.

Choose large pots for your plants as they won’t dry out as quickly as small ones. Group pots together to make watering easier.
