- Remove the weaker or less desirable branches to improve airflow and reduce competition.
3. Shape the Shrub
- Use loppers to prune larger branches and shape the shrub’s overall form.
- Create a balanced silhouette by removing branches that extend beyond the desired outline.
4. Rejuvenate Old Cotoneasters
- For overgrown or neglected cotoneasters, perform a rejuvenation pruning.
- Cut back the entire shrub to within 12-18 inches of the ground.
- New growth will emerge from the base in the spring.
5. Prune for Flowering
