With much of the UK experiencing unusually hot and dry weather, gardeners are facing a familiar summer dilemma: how do you keep plants healthy without wasting water?
As temperatures continue to soar and hosepipe bans remain a possibility in some areas, experts say a few simple changes can help gardens survive the heat while reducing water consumption and cutting household bills.
Water Smarter, Not More
One of the biggest mistakes gardeners make during hot weather is watering little and often.
Instead, plants benefit from a deep soak every few days rather than a light sprinkle every evening. Watering thoroughly encourages roots to grow deeper into the soil, making plants more resilient during dry spells.
The best time to water is early in the morning or late in the evening when temperatures are cooler and less moisture is lost through evaporation.
Collect Every Drop
A summer downpour may seem unlikely during a heatwave, but when rain does arrive it pays to be prepared.
Water butts connected to drainpipes can collect hundreds of litres of free water from roofs and sheds. Not only is rainwater environmentally friendly, but many plants prefer it to treated tap water.
Even placing buckets outside during a shower can provide enough water for containers and hanging baskets for several days.
Mulch Is Your Best Friend
Covering bare soil with mulch is one of the simplest and most effective ways to conserve moisture.
Materials such as bark chips, compost, grass clippings or well-rotted manure help lock water into the soil, reduce evaporation and suppress weeds that compete with plants for moisture.
A layer just a few centimetres thick can make a noticeable difference during prolonged hot weather.
Think About What You Grow
Many traditional cottage garden favourites struggle during prolonged dry spells. Gardeners planning ahead may want to consider drought-tolerant plants that thrive in hotter conditions.
Lavender, rosemary, salvia, verbena, sedum and ornamental grasses can all provide colour and interest while requiring far less water than thirsty bedding plants.
Mediterranean-style planting is becoming increasingly popular as Britain’s summers become warmer.
Don’t Forget Wildlife
While protecting prized roses and vegetables is important, wildlife also needs help during hot weather.
A shallow dish of fresh water can provide a lifeline for birds, hedgehogs, bees and other garden visitors. Placing pebbles in water dishes can help insects drink safely without becoming trapped.
Garden ponds should also be topped up if water levels fall significantly.
Let Your Lawn Relax
Many gardeners panic when lawns turn brown during a heatwave, but experts say there is usually no cause for concern.
Grass naturally becomes dormant during dry periods and often greens up again once rain returns. Unless a lawn is newly laid, it rarely needs watering.
Allowing grass to grow slightly longer during summer can also help it retain moisture and remain healthier during periods of drought.
Small Changes, Big Savings
According to water industry estimates, outdoor watering can account for a significant proportion of household water use during summer months.
By watering wisely, collecting rainwater and choosing plants suited to Britain’s changing climate, gardeners can reduce their environmental impact while keeping outdoor spaces looking attractive.
With July only just beginning and more hot weather potentially on the way, now may be the perfect time to make a few changes that benefit both your garden and your wallet.
After all, the greenest gardens are not necessarily those that use the most water, but those that use it most wisely.
