Why won't my hydrangea bloom?

There are several common reasons why hydrangeas fail to bloom, including:

Climate. Many hydrangeas form their buds the season before they bloom. So if you have an especially harsh winter, the buds could freeze and die.

Shade. If hydrangeas get too much shade, they won't have the energy to produce healthy blooms.

Improper pruning. Many hydrangeas won't bloom if you prune them in winter, spring, or early summer. The pink- and blue-flowering types should only be pruned right after the plant finishes blooming.

Fertilizing. If you fertilize your hydrangea too much, you could accidentally force it to put all of its energy into making lots of healthy leaves and no flowers.
