Spring Pruning in New York: What to Prune and What to Avoid

Spring is a great time to prune many trees and shrubs in New York. However, it's important to be mindful of the specific pruning requirements of your plants to ensure that you are pruning at the optimal time. Here are some general guidelines for pruning in the spring in New York:

What to Prune:

Deciduous trees (trees that lose their leaves in the fall) can generally be pruned in the spring. This is because they are not actively growing and will not be damaged by pruning. We say "generally", but any tree or shrub you plan to prune should be researched or have done a consultation with an expert prior. Evergreen trees and shrubs, such as pines and cedars, can also be pruned in the late winter or early spring. This is because they do not go dormant like deciduous trees.

What Not to Prune:

Spring-blooming shrubs, such as lilacs, azaleas, and rhododendrons, should not be pruned in the spring. These shrubs flower on old wood, meaning that the flowers are produced on branches that grew the previous year. Pruning these shrubs in the spring can remove the flower buds and prevent them from blooming. Trees and shrubs that are stressed or damaged should not be pruned in the spring. If a plant is already struggling, pruning can further stress it and may not be beneficial. Typically, removing dead or damaged branches is good. When looking to prune any other growth, it is best to follow the rule of waiting until after it has flowered.

It's always a good idea to do some research or consult with a local nursery or tree care professional before pruning. They can help you determine the best time to prune your specific plants and provide guidance on proper pruning techniques.

By following these guidelines, you can help ensure that your trees and shrubs stay healthy and thrive in the spring and beyond.
