When Is The Ideal Time Of Day To Water Hydrangeas?

Hydrangeas need more water than established plants, and it is important to avoid letting the soil dry out. Once established, water them about one inch per week, spread across three sessions, evenly distributed at the roots and never over the top of the plant. The time of day you water your hydrangeas can impact the effectiveness of watering and water loss through evaporation. It’s best to water them early in the morning or late in the evening when temperatures are cooler. When watering hydrangeas, direct the watering can or hose towards the base of the plant, rather than at the leaves, as this can encourage powdery mildew.

The best time to water hydrangeas is in the early morning, as it allows the hydrangea to enjoy the water throughout the warm, sunny day. Avoid watering during the hottest part of the day, as high temperatures can lead to faster evaporation, making the watering less effective. Morning watering allows foliage and soil surfaces to dry before nighttime, reducing the risk of fungal diseases like powdery mildew and botrytis blight. A general guideline for watering hydrangeas is to provide them with 1-2 inches of water per week, but this can vary depending on factors mentioned earlier.

It’s important to monitor the moisture of your hydrangeas and thoroughly soak them every 2-3 days instead of a light daily shower. Water in the morning to give your plant the moisture it needs to hydrate throughout the day, and apply the water directly to the base and soil. For more established hydrangeas, water when the first inch of soil feels dry to the touch. On warm days, water early in the morning or evening, as the plant is “resting” and can absorb the water best.

The best times to water hydrangeas are early morning or evening, preferably when the sun is not shining. They prefer Part Sun, and ideally afternoon sunshine, rather than early morning sunshine.
