Prune your tree hydrangeas (Hydrangea paniculata) after growth has stopped in the fall or before new growth in the spring. Tree hydrangeas can take a heavy pruning with ease. Don’t be afraid to prune them.
Your goal when pruning tree hydrangeas is to:
- Remove crossing branches.
- Remove dead branches.
- Remove last years flower buds.
- Thin out weak stems to encourage larger blooms.
- Make room for new growth.
The first time you prune your tree hydrangea it’s probably going to take a while. Take it one cut at a time and you’ll do fine.
