Regular watering is essential for summer bedding, vegetables, pots and hanging baskets as well as newly-planted trees, shrubs and herbaceous plants. In this short video, Alan Titchmarsh shows you how to water effectively, including where to direct the water, how much to give plants, how to tell if you’ve watered enough, and the best time of day to do it for maximum impact.
Plus, we explain how to water your plants efficiently to reduce reliance on mains water and help conserve this precious resource.

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.
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.
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.
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.
Using the contents of your bath to water your plants is an effective way to save mains water, especially in dry weather. Catherine Mansley, BBC Gardeners’ World Magazine, explains how to use bath water in your garden, in our Quick Tips video:
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.
If you have a lot of watering to do, a hose will save you time and effort but to make sure you only use the water you need and that it goes exactly where you want it to, use a spray gun attached to the end of your hose. Choose one that doesn’t leak or drip and look for a controllable flow option that can adjust the volume of water from 40-100%. Guns with an aerated spray control will also use less water.
Choose large pots for your plants as they won’t dry out as quickly as small ones. Group pots together to make watering easier.
