Generally, the best time to prune most trees is when they’re leafless in winter. But as you know, with each rule of thumb, there are exceptions.
Read on to learn more about spring tree pruning.
Your Guide to Pruning Trees in Spring
If you can prune your trees before they begin growing, that still counts as dormant pruning and is the ideal time to prune because of these benefits.
Once trees start budding or blooming in spring, though, double-check that pruning now won’t put your tree in harm’s way.
Can I do any pruning after trees have leaves and buds in spring?
In general, pruning in spring can limit the tree’s bloom potential for the year. Plus, trimming in spring can leave cuts on trees that leave them more vulnerable to an insect infestation or disease.
But, you can safely do some tree pruning in spring–as long as you don’t remove any more than 10 percent of the tree’s branches.
Your goal with spring pruning should be one of two things.
Pruning for safety: Remove any dead, dying or decaying branches to keep your tree (and home) safe.
Minimal pruning for aesthetics: Cut or remove branches to shape your tree a bit.
Are there any trees that are better to prune in spring?
Yes! If you’ve just planted a new tree, cut off any broken, defected or damaged limbs, then learn how to prune young trees to improve their structure.
You can also prune maple, walnut and birch trees in late spring or early summer. When pruned in winter, they tend to ooze sap. The sap does little to no harm, but some people think it’s too messy! Trimming these trees after they have all their leaves for the season reduces sap bleeding.
And, finally, prune these trees once they’re done blooming for the season in spring:
*Flowering cherry trees
*Flowering plum trees
Are there any trees I should never prune or trim in spring?
Remember: pruning trees in spring can leave them more vulnerable to insect infestation and diseases.
That’s why you don’t want to prune these trees in spring, summer or early fall:
Oak trees to reduce the chance of oak wilt
Elm trees to reduce the chance of Dutch elm disease
Sycamore trees to reduce the chance of anthracnose
Honeylocust trees to reduce the chance of stem cankers
