The same structural pruning principles that apply to trees can also be applied to most shrubs:
- Select and isolate a single dominant central leader
- Remove upward and downward oriented limbs
- Thin clusters of limbs competing for the same space
- Reduce limbs with poor taper
This is particularly important for snow load. The February 2026 North American Blizzard damaged many plants and trees throughout New England. A well-structured plant will have snow load evenly distributed on all sides of the leader.
Well-structured plants are also more adaptive for landscape changes such as adding a nearby shed or pruning to a property line.
This boxwood has not been pruned since planting. It also did not have a dominant leader extending all the way to the top so one was created by adding a splint. The splint will be removed after new growth hardens and it holds its shape.
Structural pruning is a job for hand pruning shears. Every cut is carefully placed. Hedge trimmers will promote bushy growth and poor structure and should only be used for shaping applications on plants that have previously been structurally pruned.
