Gardeners are being urged to water their plants before 10am every day this week as parts of the UK brace for high temperatures. According to experts at St. John's Garden Centres, early morning is the ideal time to water, as the soil can absorb moisture before the heat of the day sets in, and any splashed leaves have time to dry, reducing the risk of disease.
When to water your garden
The experts say there are only two suitable times to water: early morning or late evening. If mornings aren't possible, watering after 6pm is the next best option, but gardeners should avoid soaking foliage overnight, which can encourage mildew.
Watering in the middle of the day is discouraged, as most water will evaporate before it reaches the roots.
How often to water different plants
Container plants and hanging baskets should be watered daily, especially if in direct sunlight. New plants and seedlings need water every one to two days until established. Established plants and shrubs should be watered deeply one to two times per week to encourage deep root growth.
"The key is watering deeply and less frequently; this helps plants grow resilient roots that dig deep into the soil rather than relying on surface moisture," the experts added.
Signs your plants need water
Plants that need water may show wilting or curling leaves, soil pulling away from container edges, pale or scorched foliage, and a dry, dusty soil surface. The experts advise checking soil colour: dry soil is lighter and dustier, while moist soil is darker and clumps together when squeezed.
