You'll need to trim flowering quince back between autumn and before leaf break-in in springtime. This is the case with most other bushes that flower in spring. Most light pruning is generally undertaken just after flowering. Heavy structural pruning is done in winter while the plant is dormant.
When should you prune a quince tree?
Pruning quince trees is a garden task you should tackle in late fall or winter when the quince is dormant. Don't procrastinate until spring or you may eliminate your crop for the year. That is because quince tree fruits on new growth, not old growth.
How do you prune overgrown quince?
Pruning Quince
- Start at the base and remove all the suckering growth and any downward-facing branches.
- Remove any crossing limbs from the centre and any whippy growth from the top of the tree. If a branch cannot be cut with secateurs or loppers, it should be left.
