When to Prune Shrubs and Trees

Knowing when to prune trees and shrubs will help maintain the health and beauty of your landscaping plants.

Different trees and shrubs need pruning at different times of the year, mainly depending on when they bloom or set leaves. Poorly timed pruning, especially in the fall or early winter, can injure a plant and stunt or even eliminate its foliage and flower production. There are the three recommended pruning "seasons" for common trees and shrubs across the country. By following these guidelines you will be able to keep your plants healthy and maximize blooms. If you’re not sure what shrub you have, hold off pruning until right after the plant flowers.

It is also important to remember that some pruning that can be done anytime such as removing dead, weak, damaged, or crossing branches.

Late Winter/ Early Spring

Prune summer and fall-flowering plants, which will flower on the coming season's new growth, while they are still dormant. Their bare limbs make it easy to see the plant's structure, and the flush of spring growth will quickly heal wounds. Prune random-branching conifers once new growth is visible.


Abelia Beautyberry (Callicarpa species)

Butterfly bush (Buddleia davidii)

Gardenia (Gardenia jasminoides)



Ilex (Holly)

Hemlock (Tsuga species)

Juniper (Juniperus species)

Southern yew (Podocarpus macrophyllus)

True cedar (Cedrus species)

Yew (Cephalotaxus and Taxus species)

Late Spring/ Early Summer

Prune spring-flowering plants immediately after their blossoms fade. Because they produce flowers only on old growth from the previous season, pruning soon after bloom will maximize flower production the next year. Pinch the candles on whorled-branching conifers when you see new growth.

There are some trees that are best pruned in midsummer which is counterintuitive to most people with any gardening knowledge. Trees with heavy spring sap flow are referred to as “bleeders” or "bleeding" trees. To minimize the stress on the trees it is best prune bleeding trees after their leaves have fully developed.

Birch (Betula species)

Dogwood (Cornus species)

Elm (Ulmus species)

Maple (Acer species)

Yellowwood (Cladrastis lutea)

I disagree with pruning Birch (Betula species) in the middle of the summer -- especially the white bark birches. These should always be pruned in the dormant season when insect and disease pressure is low.

Dan, You raise a good point. However birches should not be pruned until the leaves have reached full size in late spring. Pruning earlier will make bleeding more likely. And do not prune in late summer even though the tree will not bleed, the unhealed cuts will start to bleed as soon as the sap starts to rise in the spring. Pruning while dormant will reduce insects and disease, but it will increase the chance of bleeding in the spring. In most cases birch trees do not require pruning anyway.
