Staying up to date with the best tree care techniques is essential for maintaining healthy, vibrant trees. While conventional wisdom suggests that the best time to trim trees is in the fall and winter, recent studies indicate that this is not always the case. In fact, pruning in the spring or early summer, when a tree is actively growing, can promote faster healing and reduce stress on the tree.
On the other hand, trimming during the dormant season can slow down a tree’s ability to heal. It also increases the risk of disease and allows insects to feed on exposed wood. In this guide, we’ll discuss the best time to trim trees based on different species and circumstances.
Tree Pruning & Trimming Schedule
Late Winter Pruning
Trimming in late winter helps wounds heal quickly and minimizes exposure before new growth emerges. With fewer leaves in the way, it’s also easier to assess which branches need to be pruned.
Prune After Blooming
For early-blooming trees and shrubs that rely on the previous year’s growth, trim them as soon as they finish blooming.
Prune Before New Growth
If you grow plants primarily for their foliage rather than flowers, prune them in early spring before new growth begins.
Hedges and Shrubs
Hedges need frequent pruning, especially after their initial planting. Typically, they should be trimmed twice a year—once in the spring and again in mid-summer.
Best Time to Trim Trees by Type
Not all trees thrive with pruning during the same seasons. Here’s a breakdown of when to trim different types of trees.
-
Flowering Trees
The best time to trim flowering trees, such as crape myrtles, dogwood, and magnolia, depends on their blooming cycle. Trees that bloom on new growth should be trimmed in late winter or early spring before the growing season starts. If a tree blooms on old wood from the previous year, wait until after it has flowered before trimming.
-
Deciduous Trees
Deciduous trees like oaks and willows are best pruned when they are dormant, usually in late fall or winter. This timing minimizes the risk of diseases and insect infestations. However, some trees, such as maples, may “bleed” sap when cut in late winter, so pruning in late summer or early fall can be an alternative.
-
Young Trees
Newly planted trees generally don’t require immediate pruning. Waiting a year before trimming allows them to establish strong root systems. However, removing any broken or damaged branches in the first year is necessary. As the tree grows, gradually shape it to encourage a strong, well-formed structure.
-
Newly Planted Trees
Similar to young trees, recently planted trees should not be heavily pruned right away. Premature pruning can weaken their ability to establish roots and produce food. Only remove dead or damaged branches in the early stages, and wait until the tree is well-established before performing any major trimming.
Examine the tree before making any cuts. Recently planted trees usually require corrective pruning. To protect the tree, maintain the health of the lower branches, like young trees. It provides nourishment as well during its formative years. To determine whether or not you need to fertilize, test your soil.
-
Subtropical Trees
In states like Florida and California, where trees grow year-round, trimming can be done at almost any time. However, it’s important not to remove more than 30% of a tree’s live tissue in a single pruning session, regardless of the season.
-
Fruit Trees
To encourage strong fruit production, fruit trees should be pruned in late winter or early spring. Some trees can also benefit from light pruning in late summer, but excessive cutting during this time can weaken them. Proper pruning allows for better sunlight exposure and airflow, which leads to larger, healthier fruit.
-
Evergreen Trees
Unlike deciduous trees, evergreen trees such as spruce and fir don’t go completely dormant. They may slow down in winter but continue to grow. The best time to trim evergreens is in late winter or early spring before new growth begins. Pine trees, however, should be pruned in late spring or early summer.
-
Mature Trees
Mature trees benefit from pruning in late fall or early spring when they are dormant. The exact timing depends on the species, but it’s crucial to avoid pruning during periods of active disease spread.
Why Is Fall and Winter Often the Best Time to Trim Trees?
Pruning at the right time is vital for maintaining tree health. In the fall, trees slow down their internal processes in preparation for dormancy. This dormancy protects them from winter’s harsh conditions. By trimming trees during this time, they can heal before the arrival of spring when diseases and insects become more active.
