The best time of year to prune trees and shrubs is early spring or early fall because these periods coincide with the natural growth cycles of most plants. In early spring, trees and shrubs are still dormant, which minimizes stress on the plants while allowing for improved healing once they begin to grow after pruning. This timing ensures that the wounds from cuts are sealed quickly during the active growing season.

In early fall, pruning can also be beneficial as it prepares the plant for winter by removing any dead or damaged branches, thus promoting healthy growth for the next spring. However, caution should be used in the fall to avoid stimulating new growth that might not survive the winter.

Pruning in other seasons, such as late summer or anytime during the year, can disrupt the plant's growth and lead to stress, making it more susceptible to disease and pests. Therefore, timing is crucial for effective pruning and the overall health of trees and shrubs.
