Plan ahead and save water; Water companies are unlikely to introduce hosepipe bans this summer, but this should not make gardeners complacent, says Hannah Stephenson.
Gardeners should always take a common-sense approach to watering and not reach for the sprinkler at the first sign of a sunny spell.
A sprinkler can use up to 1,000 litres of drinking water, or 220 gallons, in an hour, which is more than a family of four would normally use in a day.
There are so many products on the market now to help us save water that there's really no excuse not to, from controlled irrigation systems where sensors monitor the moisture in the soil and only water your plants when the soil really needs it, to bath water diverters which send all your "grey" water to your water butt.
Add to this an increasing choice of drought-tolerant plants and hopefully the sprinkler will become a thing of the past.
If you must use annuals, which are notoriously thirsty, keep them in pots rather than borders and go for ones which can withstand drier situations, like pelargoniums, gazania and osteospermum.
If you are creating new beds and borders, consider drought-resistant plants such as lavender, Sedum spectabile, lamb's ears and ornamental grass such as Stipa tenuissima, while middle-sized drought-resistant plants include Echinacea purpurea 'Magnus', Erysimum 'Bowles's Mauve' (wallflower), Russian sage and Nepeta 'Six Hills Giant' (catmint).
At the back of the border you could use species more than 1.8m tall, including Cotinus coggygria 'Royal Purple', Choisya ternata (Mexican orange blossom) and Trachelospermum jasminoides.
Most drought-tolerant plants will have either aromatic leaves, fleshy and succulent leaves (which store moisture for dry spells), grey leaves, hairy leaves (which shade themselves with their own hairs), long narrow leaves (which are good at shedding heat without water), or spikes (which act as 'fins' to cool the plant).
Don't water established lawns - if we have a long hot spell they may turn a bit brown, but they will recover with the autumn rains. Leave them to grow a bit longer to preserve water and introduce drought-tolerant clovers and trefoils which will prevent the lawn from changing colour completely when a dry spell hits.
Try to recycle water as a matter of course. Use a plastic bowl for washing up then deposit the water on to your plants, as a small amount of washing up liquid isn't going to hurt them. Save the really dirty washingup water for tougher plants such as mature shrubs and trees.
Bath water can also be re-used if you install a diverter which redirects water from the downpipe into a water butt.
The organisation Waterwise (www.waterwise.org.uk), which promotes water-saving and conservation, recommends attaching a trigger nozzle on your hosepipe to halve the amount of water used and help direct the flow to the root of your plants.
Up to 85,000 litres of rain falls on your roof each year so install a water butt and use it to water your plants and wash your car. If you're not sure which water butt to buy, check out the Waterwise guide to waterbutts on its website.
Watering cans can significantly reduce the amount of water used while getting the desired amount to your plants.
Don't water in the heat of the day - do it early morning or early evening to reduce evaporation, and mulch over thirsty specimens to conserve moisture.
If you have plants in pots, gather them together to create a little micro-climate and again reduce evaporation, and you can water them all together. But it's preferable to use the biggest pot you can afford for patio plants, which will require less watering than smaller containers.
Some more thirsty specimens in pots may benefit from being placed on a tray lined with capillary matting, which soaks up the water and then delivers the moisture to the roots, gradually when it's needed.
It's handy if you're going away and don't have someone to water the garden for you in summer.
Alternatively, place one end of a strip of capillary matting in an elevated bucket of water and the other end in the compost in your pot and it should hopefully filter through over a prolonged period.
With luck, you shouldn't need to get the sprinkler out again.
Opt for drought- <B tolerant plants for the garden such as Trachelospermum jasminoides, above, and Choisya ternata,
