watering

Bigleaf Hydrangeas prefer moist soil and should be watered often to keep the top 5-8in of soil slightly moist. Watering every 3-4 days during the summer months is ideal. In drier climates, you may need to water every 1-3 days. During the winter, you can reduce watering to once per 7-14 days. Additionally, Bigleaf Hydrangeas should receive 1-2 inches of water during each watering session. It is important to avoid over-watering these plants, as they can be prone to root rot.

sunlight

Bigleaf hydrangeas prefer bright, indirect sunlight, such as in a north or east-facing window, for 4-6 hours a day. This plant species can also tolerate partial shade, but too much direct sunlight can scorch the leaves. For best blooms, it is recommended that you keep your hydrangea in a spot that gets morning sun and afternoon shade, or all day shade.

pruning

Bigleaf hydrangea should be pruned annually in late winter or early spring, just before new growth appears. Pruning should be done minimally and very selectively, removing no more than about 1/3 of the stems each year. When doing selective pruning, focus on removing the oldest, woodiest stems. This will promote new, vigorous growth and help to keep the shrub from becoming too leggy.
