Proper pruning and protection of shrubs and trees will help them survive the winter months, and will lead to healthy growth come spring.
Step 1: Identify shrubs and prune accordingly. Shrubs that bloom in the spring should be pruned immediately after flowering. Shrubs that bloom in the summer should be pruned during the dormant winter months. Shrubs should not be pruned late in the growing season as it will promote new growth that can be damaged by winter frost. Prune summer-blooming shrubs during the dormant winter season.
