I want to prune my shrub roses and hydrangea so they do not outgrow their...
Pruning Tips for Hydrangeas: 1.) Blooms on Old Wood: - Old Wood consists of stems that have been on the plant since the summer before the current season. - These Hydranges set their flower buds for the next year in August, September or October. Pruning basics: 1.) All dead wood should be removed every year. This can be done at anytime of the year. 2.) After the plant is 5 or more years old, remove 1/3 of the oldest canes, by cutting them down to the ground, to rejuvenate the plant. This can be done in early spring or at the end of the summer. 3.) Pruning plants to control size should be done in June or July before the plant starts to set flowering buds for the following summer. 4.) Deadheading = removal of old flower heads. Deadheading can be preformed anytime of the year.
- In June or July, deadheading can be preformed with long or short stems with out worrying about removing next years flower buds.
- After August, deadheading should be preformed with short stems to preserve next years flower buds.
- Prune in the fall or early winter to control size. This can be done in two ways:
- The only type of Hydrangea that can be pruned into a tree form
- Can be pruned in fall, winter or spring
- Does not need to be pruned every year except to control size
- Crossing branches should be removed each year
- Cut other branches to train shrub into a pleasing shape
- Remove all dead wood. This can be done anytime of the year.
- Once the plant is 5 years or older, remove 1/3 of the oldest canes by cutting them done to ground level to rejuvenate the plant.
- Prune to control size in early spring or late fall.
