As colder weather draws closer, deciduous shrubs will stop producing new leaves and begin to lose their foliage. Once this happens, it’s time for winter pruning. Many deciduous shrubs respond very well to dormant season pruning and will produce healthier foliage and more abundant blooms. Winter pruning is an opportunity to help the plant renew itself and stay healthy. Here are the steps to take to winter-prune your shrubs.

The Importance of Winter Pruning

Deciduous shrubs need winter pruning to ensure they have a healthy, vigorous growth cycle.
