Hydrangeas require ample water to produce their showy blooms, but the frequency of watering depends on the species, soil type, location in sun or shade, and climate. Outdoor hydrangeas should be watered deeply once a week, providing enough water to soak the soil to a depth of at least 6 inches. However, during periods of hot, dry weather, it may be necessary to water more frequently.
Endless Summer hydrangeas have medium to high water needs, so they should be kept evenly moist but not waterlogged throughout the growing season. Watering frequency will vary depending on the region’s climate conditions. They don’t need much water during winter but should be watered about once every month.
Watering is generally recommended to be 1 inch (2.5 cm) per week, either by rainfall or irrigation. Watering should be done routinely each week, up to twice a week during hotter months. The best way to water hydrangeas is to water them deeply when the soil is dry to the touch. Adjust watering based on weather, with more in heat and less in rain. Watering in the morning helps them stay hydrated for the day, and it’s important not to overwater, which can cause the blooms to droop.
In summary, hydrangeas require adequate water to produce their showy blooms, but the frequency of watering may vary depending on the region’s climate.
