What to Prune Now and What to Leave Until Spring
Winter is one of the best times to prune many trees and shrubs. With plants dormant and leaves gone, structure is easier to see and pruning causes less stress. When done correctly, winter pruning promotes healthier growth, better shape, and fewer problems once spring arrives.
This guide explains what to prune in winter, what to avoid, and how pruning differs by plant type and growing zone. It’s part of our complete winter tree and shrub care series designed to help plants thrive year-round.
Why Winter Is a Good Time to Prune
During winter dormancy, trees and shrubs are not actively growing. This makes pruning less stressful and reduces the risk of disease and pest issues.
Benefits of winter pruning include:
-
Cleaner cuts with faster spring healing
-
Improved plant structure
-
Reduced risk of spreading disease
-
Better airflow and sunlight penetration
-
Stronger spring growth
Winter pruning is especially effective for deciduous trees and many non-flowering shrubs.
What Trees and Shrubs Should Be Pruned in Winter
Deciduous Trees
Most deciduous trees benefit from winter pruning.
Winter is ideal for:
-
Shade trees
-
Ornamental trees
-
Fruit trees
Without leaves, it’s easier to see crossing branches, weak limbs, and overall shape.
Non-Flowering Shrubs
Shrubs that do not bloom in early spring are good candidates for winter pruning.
These shrubs typically bloom on new growth, so pruning now encourages fuller growth later.
Fruit Trees
Winter is one of the best times to prune fruit trees.
Pruning fruit trees in winter helps:
-
Improve airflow
-
Encourage stronger fruiting wood
-
Reduce disease pressure
-
Control size and shape
Always use clean, sharp tools when pruning fruit trees.
What NOT to Prune in Winter
Avoid winter pruning for:
-
Spring-flowering shrubs that bloom on old wood
-
Plants that are actively blooming in winter
-
Shrubs prone to cold damage when freshly cut
Pruning spring bloomers in winter may remove flower buds and reduce blooms.

Watch for freeze-thaw cycles after pruning
Zones 8–10
-
Winter pruning is often extended

Avoid pruning too early on frost-sensitive plants
-
Time pruning before active spring growth begins
How to Prune Trees and Shrubs in Winter
Follow these basic winter pruning principles:
-
Remove dead, damaged, or diseased branches first
-
Cut crossing or rubbing branches
-
Avoid removing more than 25 percent of the plant at one time
-
Make clean cuts just outside the branch collar
-
Step back often to assess shape and balance
Less is more. Proper pruning improves health without over-stressing the plant.
Supporting Plant Health After Winter Pruning
Pruning creates small wounds that plants must heal. Supporting overall plant health during winter helps trees and shrubs recover more efficiently.
Focus on:
-
Proper winter watering
-
Mulching to protect roots
-
Avoiding high-nitrogen fertilizers
Root-focused support during winter can help plants transition smoothly into spring growth without forcing new foliage too early. MitoGrow is our favorite for supporting roots during cold weather and all year round.
Trees and Shrubs That Commonly Benefit From Winter Pruning
Winter pruning is especially common for:
-
Deciduous Shade Trees
-
Non-Flowering Shrubs
These plant categories are often pruned in winter to prepare for strong spring growth and improved structure.
Common Winter Pruning Mistakes to Avoid
-
Pruning spring-flowering shrubs too early
-
Cutting during extreme cold
-
Over-pruning dormant plants
-
Using dull or dirty tools
-
Ignoring plant-specific pruning needs
Taking a thoughtful, moderate approach prevents long-term damage.
Final Winter Pruning Tips
Winter pruning is about preparation, not perfection. Focus on removing problem branches, improving structure, and reducing stress before spring growth begins.
Combined with proper winter watering and mulching, winter pruning sets trees and shrubs up for a healthier, more vigorous growing season.
