LifestyleGardeningGardeningUK gardeners can save their hanging baskets from heatwave damage with these expert watering and positioning tips11:56, 25 May 2026The UK heatwave looks set to continue for several more days, and for those tending their gardens, the damage may already be taking hold, according to one horticultural expert. This is particularly concerning for plants housed in containers, such as hanging baskets. While they look spectacular and bring a vibrant splash of colour to any garden, they are incredibly susceptible when confined to small pots.‌Luke Newnes, garden expert at Hillarys, said: "Most gardeners are heading into the heatwave thinking the hard work is done-the bedding plants are in, the hanging baskets are up, everything looks great. But anything planted in the last few weeks has not had a chance to harden off and establish properly.‌"When you hit 26C or above, those plants are genuinely in danger. Compost in a small container can go bone dry in under 2 hours in direct midday sun.‌"A hanging basket in full sun on a hot day is basically a plant on life support."The gardening specialist insists the "most important" action any gardener can take is to relocate container plants, including hanging baskets, into a shaded spot, the Express reports.This applies to anything that isn't drought-tolerant.‌The expert added: "Water everything deeply in the evening to build up reserves before the heat arrives."Morning is best for watering during the heatwave itself, before 9am if you can.‌You are not going to scorch leaves by watering in the sun; that is a myth, but the real problem with midday watering is that the water evaporates before the roots can use it, so it is a wasted effort."If relocating the plants is not an option, consider using shade cloth or a garden awning to lower the temperature.According to the expert, this can make the difference between a "plant coping" and a "plant wilting".Article continues belowLuke noted: "Do not fertilise anything in the heat, as stressed plants cannot take up nutrients and you risk root burn. Wait until temperatures drop."It is equally important to refrain from pruning or cutting anything back, as this can leave plants exposed and susceptible to sun damage.Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌HeatwaveGardening
