Climbing rose trees are special and you can’t prune them like you would conventional rose trees.
The pruning of a climbing rose tree must help the rose bush climb further on its support structure, while maximizing blooming.
Note, though, that such pruning should only be performed on specimens at least 3 years old.

Pruning climbing rose trees
Repeat-blooming climbing rose trees, those that bloom several times a year, require pruning in February or March.
- At the end of winter and when freezing is over, prune short sprigs along the main climbing branch, so that they form a shape like a fishbone.
- Begin with eliminating dead wood that has dried up.
- Remove the oldest branches, the “old wood”. Don’t be afraid of removing these branches, because once they’re gone, young stems become more vigorous and bear more flowers.
- Finally, the pruning itself: keep 5 or 6 of the most vigorous branches and prune side shoots to more or less 3 buds. This means pruning every single side shoot to around 8 to 12 inches (20 to 30 cm) from their base on the main stem (the “fishbone”).
- Those main branches will form the structure of the bush.
As for once-blooming rose trees, which only flower a single time in the year, follow these same steps but only after the blooming.
