Portland’s Best Tree Trimming and Pruning Service

Tree pruning in Portland depends on the specific needs of each tree. While general guidelines exist for different types, timing, and frequency of pruning, adjustments are often necessary based on the unique circumstances and goals of each tree owner. In an urban environment rich with trees, understanding these nuances is crucial. This guide provides an overview of the best practices for tree pruning in the greater Portland metro area.

Ideal Tree Pruning Frequency

Deciduous Trees

Deciduous trees in urban settings, like Portland, typically benefit from pruning every 3-5 years. This interval may need to be shortened if trees are close to or over structures. Heavy pruning to avoid regular maintenance can cause significant new growth, necessitating more frequent follow-ups. Phill Snell understand the delicate balance required for optimal tree health.

Evergreen Trees

Large fir and pine trees should be pruned every 5-7 years. Regular inspections are essential to monitor health changes that might affect pruning schedules. Cedars and other evergreens usually require pruning every 3-5 years, especially if they are near structures. Consulting a professional arborist ensures your trees receive the best care.

Ornamental Trees

Ornamental trees, such as Japanese Maples, can be pruned based on the owner's aesthetic preferences. These trees are often pruned yearly or biennially, though some may need pruning twice a year to achieve the desired look.

Timing of Tree Pruning

The best time to prune depends on the tree's type and condition. If your tree hasn't been regularly maintained, the best time to prune is now. For trees on a regular pruning schedule, timing will vary based on the tree type and your convenience.

Types of Pruning

Full Pruning

Full pruning enhances the natural form of trees and shrubs by removing dead, diseased, rubbing, and duplicated limbs. We typically remove 10-20% of the tree crown, improving aesthetics and health by increasing air circulation, which helps prevent insect colonies and fungal growth.

Heavy Thinning

When a tree grows too large for its setting or too old to support distant growth, crown reduction pruning is recommended. This technique involves cutting back tips and leaving certain leaders to create a new, lower crown. Unlike topping, which we do not perform due to its negative impact on tree health, crown reduction promotes healthy growth.

Crown Restoration

For trees that have been topped, we begin restoration by reducing the number of leaders competing for light and spacing them evenly. Over several years, this process can reclaim a "ruined" tree, restoring its health and vitality.

Crown Lifting

Crown lifting involves pruning the lowest limbs of tall, straight trees like pine and fir to encourage upward growth and maintain health. This technique anticipates the natural shedding of lower limbs as the tree grows taller.

Formal Pruning

Trees planted for fruit, flowers, or to fit into confined spaces can be pruned formally to maintain a desired shape. Regular and proper formal pruning ensures these trees remain both beautiful and functional. If a tree has been neglected, we aim to save it, but if not possible, we recommend removal and replanting.
