Roses, beloved garden plants that bloom throughout summer, require proper watering to stay healthy. The Royal Horticultural Society (RHS) recommends watering them in the morning to minimize the risk of fungal diseases such as mildew and black spot. Morning watering allows foliage to dry during the day, reducing moisture that encourages fungi.
Why Morning Watering Is Best
Watering in the morning also reduces water evaporation due to cooler temperatures, ensuring more moisture reaches the roots. In contrast, watering during the hottest part of the day can cause water droplets on leaves to burn and scorch the plant. The RHS advises directing water onto the soil around the base, avoiding foliage and flowers, which further deters fungal diseases and prevents water waste.
Evening Watering Considerations
If morning watering is not possible, gardeners can wait until late evening after sunset. However, evening watering may attract slugs, which can damage other plants in the garden. Established roses should be watered once a week during dry spells, with a deep soak rather than light, frequent watering.
Additional Care Tips
Roses are deep-rooted and thirsty plants, especially in hot weather. Signs of underwatering include wilting, dull leaves, and stunted growth. Container-grown roses lose moisture faster and may need extra water. Regular feeding throughout the growing season also helps roses produce more blooms for longer.
According to the RHS, consistent deep watering and proper timing are key to healthy roses and abundant flowers.
