Roses can grow healthier and produce fuller blooms in summer if gardeners avoid a common watering mistake in July, according to experts at April and Ashley, a florist. The key is to water at the base of the plant rather than from above.
Why Overhead Watering Harms Roses
After weeks of hot weather, much of the UK has turned cloudy and wet, creating ideal conditions for fungal diseases. Roses are hardy but susceptible to black spot, powdery mildew, rust, and mould when foliage stays wet. Fungal spores need water to germinate and infect the plant.
Watering from above leaves moisture on leaves, increasing disease risk. It also wastes water as much evaporates before reaching roots. Roses need about 3-5 gallons per week, but proper application is crucial.
Expert Advice on Proper Watering
April and Ashley stated: “It goes without saying that roses need water – about 3-5 gallons per week. But it’s important to strike the right balance between hydration and preventing excess retention.” They added: “Overhead watering…can cause excess moisture buildup on the foliage – leading to fungal infection. Protect your roses from disease by watering at the base of the plant instead of from above.”
Watering at ground level keeps roots hydrated, helps plants stay cool, and encourages deeper root growth. Deeper roots store more energy and water, leading to better flowers and less frequent watering.
Best Practices for July Watering
Water roses two to three times a week, aiming at the base. If using a sprinkler, set it for early morning so foliage dries before midday heat. Avoid afternoon watering due to evaporation and evening watering due to cold and disease risk.
Proper watering is essential for healthy roses throughout summer, preventing disease and ensuring abundant blooms.
