How Often Should Established Hydrangeas Be Watered?

Hydrangeas require watering once or twice per week, depending on environmental conditions. To ensure optimal growth, it is essential to water hydrangeas below the leaves and flowers at the base of the plant. Soak your hydrangea in water to hydrate the roots before planting it in the ground, then water copiously. Water frequently for several weeks afterward to help the plant establish well. Mulching can also help.

The amount of water hydrangeas need depends on the species, soil type, location in sun or shade, and climate. Deep weekly watering is usually enough if you don’t get enough rain, but may need more frequent watering in hot, dry weather. Hydrangeas should be watered deeply 1-3 times a week, some of which can be from rainfall.

For more established hydrangeas, water when the first inch of soil feels dry to the touch. Once established, hydrangeas should be watered about one inch per week, spread across three watering sessions. The water should be evenly distributed.

To ensure optimal growth, thoroughly soak your hydrangeas every 2-3 days instead of a light daily shower, which may not seep far enough down to impact the roots. Overall, these tips provide all the information needed to care for hydrangeas effectively.
