Pruning is one of the most important things you can do for the health, safety, and beauty of your trees.
In Washington’s unique Pacific Northwest climate, knowing the right time to prune is essential for avoiding disease,
promoting healthy growth, and ensuring your trees look their best all year round.
Why Tree Pruning Matters
- Health: Removes dead, diseased, or damaged branches to prevent decay and pests.
- Safety: Reduces the risk of falling branches during storms.
- Shape & Structure: Encourages balanced growth and improves the tree’s appearance.
- Sunlight & Airflow: Allows more light to reach your lawn and improves air circulation through the canopy.
Best Time to Prune Trees in Washington
Washington’s seasons have a direct impact on pruning schedules. While general guidelines apply, the exact timing depends on your tree species.
Winter (December – February)
Winter is the ideal time for most deciduous trees. With the leaves gone, it’s easier to see the tree’s structure and identify problem areas.
Pruning during dormancy minimizes sap loss and reduces the risk of pest infestation.
Spring (March – May)
Spring is a time of rapid growth, making it great for minor shaping. However, avoid heavy pruning of flowering trees until after they bloom.
Summer (June – August)
Summer pruning can slow growth in overly vigorous trees and is useful for correcting problem limbs. Avoid major cuts during extreme heat to reduce stress.
Fall (September – November)
Fall pruning should be minimal. Fresh cuts may not have enough time to heal before winter, leaving the tree vulnerable to disease.
Tree-Specific Pruning Tips
- Maple Trees: Best pruned in mid-summer to reduce sap bleeding.
- Cherry & Plum Trees: Prune in late summer to prevent bacterial canker.
- Conifers (Douglas Fir, Western Hemlock, Pine): Light pruning in late winter or early spring is ideal.
- Fruit Trees: Late winter or very early spring encourages better fruit production.
Signs Your Tree Needs Immediate Pruning
- Dead or hanging branches
- Branches rubbing against your home or power lines
