Gardening expert and TikTok creator Ish has shared essential advice for keeping plants hydrated during summer heatwaves. The key, he says, is watering at two specific times of day: early morning between 7am and 9am, or in the evening from 9pm onwards. These cooler periods reduce water evaporation, ensuring the soil absorbs moisture effectively.
Why Timing Matters
Watering when the ground and air are cooler minimises evaporation, leaving plants properly hydrated. Ish explained in a recent video: "Now, what I always tell people is water them in the mornings or evening, it's completely up to you." This approach applies to both garden plants and lawns.
Myth Busting: Watering During Peak Heat
Despite common belief, Ish says it is safe to water plants during the hottest part of the day if they show signs of distress. He debunked the myth that water droplets act like magnifying glasses and burn leaves: "It's a common myth that it's going to burn them, it's not a giant magnifying glass with the water droplets, so don't worry." He advises applying water directly to the soil for maximum benefit.
Additional Tips for Plant Survival
Ish recommends moving potted plants into the shade to help soil retain moisture. Placing light-coloured gravel on top of the soil reflects sunlight, preventing overheating and evaporation. For garden beds, setting up a shade screen—available at DIY stores, garden centres, or online—or using a fitted white sheet provides affordable protection. He said: "That way then, I can keep them well-watered in one space; group them close together so if it does get any sunshine, it's not getting directly to the soil which isn't drying out and, as a result, will survive throughout the heatwave." For plants fixed in the ground, a thorough morning watering suffices.
