Pruning tips for shrubs

By: Garden Gate staff
Do you know which of your shrubs could benefit from pruning? We do! Check our list to find out.

Get your pruning shears ready! Here’s a list of 37 common shrubs that respond well to maintenance pruning. And if you do it on a regular basis — once a year on most shrubs — it’s an easy task. Since there are no drastic cuts, the shrubs fill in again in just a few weeks, too. So think about which of these shrubs you have in your garden — you may have at least one that could be improved by a bit of pruning right now!

Plant Name Best time to prune Cold/Heat Zones Tips
Abelia, glossy Abelia xgrandiflora Winter 6-9/9-1 If needed, thin out the oldest stems to the ground each winter to keep this shrub in shape
Azalea Rhododendron hybrid Late spring to early summer 4-9/9-1 Slow to recover from heavy pruning; taking off too much may retard blooming for a year or two
Barberry Berberis spp. Late spring to early summer 4-8/8-1 Pruning is the same for both deciduous and evergreen types; thorny, so always wear gloves
Bayberry, northern Myrica pensylvanica Early summer 3-7/7-1 Maintain natural, informal shape and size with light pruning; rarely needs rejuvenation
Burning bush Euonymus alatus Anytime 4-9/9-1 Prune before new growth for a more casual look or after new growth for a tighter, more formal appearance
Camellia, Japanese Camellia japonica Late spring 6-8/8-1 Slow to recover from heavy pruning so try to keep it in shape with more frequent light trimmings
Carolina allspice/sweetshrub Calycanthus floridus Spring or late summer 4-9/9-1 Lightly prune to maintain form
Chastetree Vitex agnus-castus Late winter 6-9/9-1 Shrubs can be pruned quite severely; prune tree-form specimens only lightly

Deutzia Deutzia spp. Early summer 5-8/8-1 Blooms better with annual pruning
Dogwood, red twig Cornus alba Winter or early spring 2-8/8-1 Hard pruning in early spring produces the most colorful stems for winter interest
