With hosepipe bans becoming more common during dry spells in the UK, gardeners are increasingly looking for smart, sustainable ways to keep their gardens green. Fortunately, there are plenty of creative methods to water your plants.
Whether you’re working with a small urban garden or a larger green space, here are some ideas to make every drop count.
Harvest rainwater
Rainwater is free, natural, and far better for plants than chemically treated tap water. Installing a water butt under a downpipe is one of the easiest ways to collect rain from your roof or shed. You can even link multiple water butts together if you have the space. The best bit? With the Best of British weather, a water butt helps you to appreciate the inevitable summer rain!
Reuse household grey water
Water from washing up, baths, or even cooking (once cooled) can be reused in the garden. As long as you’re not using harsh chemicals, most plants are happy with lightly soapy or starchy water.
DIY self-watering mechanisms
If you’ve got empty plastic bottles lying around, turn them into slow-release watering devices. Poke a few small holes in the cap, fill the bottle with water, and bury it upside down near the base of a plant. Water will gradually seep into the soil as needed—perfect for busy gardeners or while you're on holiday.
Use ollas or terracotta pots
Ollas are unglazed clay pots buried in the ground and filled with water; a method used for centuries but regaining popularity in modern gardening. Moisture seeps through the porous walls, delivering water directly to the roots. You can buy purpose-made ollas or try using old terracotta pots with the hole blocked.
Mulch like a pro
Mulching helps you to make the most of the water you do use. A thick layer of mulch helps lock moisture into the soil and keeps roots cool in hot weather. It also improves soil structure and keeps weeds down.
Plant smart
Choose drought-tolerant or native plants that are adapted to our temperamental British weather. Mediterranean herbs like rosemary, thyme, and lavender thrive in dry conditions and need very little watering once established. Grouping plants with similar water needs together also helps you avoid overwatering.
Water at night
It’s not just how you water, it's when. Early morning or late evening is best, as water has time to soak in before the sun evaporates it. Watering in the heat of the day wastes water and can even scorch delicate leaves.
Watering your garden doesn’t have to mean hefty water bills. By getting creative and thinking sustainably, you can keep your plants healthy while conserving water and cutting down on your bills. With the UK’s changing climate, small changes like these can make a big difference—not just to your garden, but to the planet too.
