When to cut back hydrangeas
The best time to start pruning your hydrangeas is in the early spring – ahead of the growing season – and in the late winter.
Spring officially starts on March 20 in the UK, meaning you still have a few weeks before having to spruce up your shrubs.
If you have climbing hydrangeas, you can leave the pruning for later in the summer, after they start to flower.
Dead-heading your hydrangeas can play an integral role to the health of your shrub.
