A few are best pruned annually to keep them well shaped and flowering strongly.A hard prune can be done when the viburnum spreads too much, gets too leggy, or overgrown. Cutting larger, unsightly branches helps to thin out the shrub.Light pruning can be performed any time throughout the growing season, but late winter or early spring is the best time to complete a hard pruning if needed.

How do I prune viburnum?
To shape a viburnum, prune it lightly immediately after flowering. Remove the flower heads and cut back any branches that spoil the shape of the shrub to a pair of newly-sprouted leaves. Remember that removing the flower heads will preclude the formation of fruit, which can be very attractive in many viburnums. If you wait too long into spring to prune them, you’ll waste plant energy on growth that’s then removed. Worse, you could delay blooming or possibly eliminate that year’s flowers if you cut the plants just before they were ready to bloom in July, August, or September.Rhododendrons and azaleas Because they bloom on old wood, pruning in fall will remove the flower buds and prevent spring blooms. To avoid this, aim to prune your azaleas and rhododendrons in late spring to early summer, ideally within three weeks after they’ve finished blooming.Most spring-flowering Viburnum bloom on old wood and must be pruned right after they finish flowering. Summer-flowering types bloom on new wood and can be pruned during their dormant period, typically late winter through early spring.Generally, the best time to prune or trim trees and shrubs is during the winter months. From November through March, most trees are dormant which makes it the ideal time for the following reasons: Trees are less susceptible to insects or disease.
Can you prune viburnum in winter?
Prune evergreens in spring when the fear of frost has vanished – sappy new growth prompted by pruning needs time to mature – and prune back deciduous viburnums during the dormant season. Viburnum tinus, which can also be used to make a hedge, is best trimmed in the spring, though a second cut might be necessary. What should I avoid pruning in winter? Avoid pruning spring‑flowering shrubs (like lilacs and forsythia), azaleas, rhododendrons, and andromeda, as well as heavily cutting evergreens in winter. These plants either set their flower buds the previous year or are more vulnerable to cold damage after strong winter cuts.Trees and Shrubs Are Dormant in Winter You’ll do less damage now when you prune, shape and thin your deciduous plants than if you had at it in their prime growing months. Those fresh pruning cuts you make heal faster during the dormant season — and are less likely to attract insects, which can carry diseases.During extreme heat or cold. Your tree is already stressed at this time, so making a cut can put it under more pressure and make it susceptible to disease, drought, or drying out. Pruning before the tree blooms not only removes the beautiful flowers, but it forces the tree to use stored energy to replace these buds.
How to rejuvenate an overgrown viburnum?
Viburnums respond well to hard pruning and recover quickly. The best time to rejuvenate an old shrub is in late March or early April when the shrub is dormant. Keep in mind that heavy pruning will likely affect blooming that season. Healthy specimens rarely need pruning. Prune viburnums after flowering only if pruning is necessary for shaping. Old or crowded plants may be thinned and shortened to bring flowers to eye level. After 4 to 5 years you may remove 1/3 of the oldest stems, and thereafter prune every 2 or 3 years.

Use a sharp pair of bypass hand pruners when pruning Viburnum. For renewal pruning, you’ll want to trim them in the summer after their blooms have faded. If you do a light renewal prune in spring, you’ll cut off all their flower buds, and all you’ll get is leaves.

Just remove the dead flower. Note: For very old or tall plants, you can prune hard to rejuvenate. It won’t die, but it won’t flower that year.Preventative pruning, and major pruning, should be done early in the spring, while the plant is dormant. Minor pruning, shaping, and trimming can be done all summer as needed. Don’t prune plants too heavily in the fall, when plants are getting ready for winter.Most people say don’t prune in the fall. Late winter/early spring generally is the best time. Pruning stimulates new growth and that’s not what we want at this time of year because the plants are storing energy for the winter and this will stress them out.
