Hydrangea General Information

Hydrangea are superb in the border for summer and autumn color. This shade-tolerant shrub is perfect for under trees and in the shadows of buildings. Provides winter interest too if flowers are left on. Great for indoor decorating as their flowers are easily dried. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Color can be affected by soil pH. Easiest pruning is to simply remove any dead canes that are not sprouting leaves in the spring. Compact habit requires little pruning, but best time is after it is done blooming if shaping is desired.
