The best time to prune a viburnum depends on the specific type of viburnum you have and what you're trying to achieve:
For most viburnums that bloom in the spring:
* After flowering: This is the ideal time to prune for most viburnums that bloom in the spring. Prune right after the flowers fade to encourage new growth and maintain the plant's shape. Pruning before flowering will remove the buds that would have produced flowers.
* Late winter or early spring: If you need to shape your viburnum significantly, you can prune it back in late winter or early spring, before new growth begins. This can be done before the buds start to swell.
For viburnums that bloom in the summer or fall:
* Early spring: Prune these viburnums in early spring, before new growth begins. This will ensure you don't remove any flower buds.
General pruning guidelines for viburnums:
* Shape and size: Prune after flowering to remove any crossing or dead branches, or to maintain the plant's shape.
* Rejuvenation: If your viburnum has become overgrown or leggy, you can prune it back to the ground in late winter or early spring. This will stimulate new growth and rejuvenate the plant.
* Deadheading: To encourage more blooms, you can deadhead the spent flowers.
* Avoid over-pruning: Viburnums don't need a lot of pruning, so only prune them when necessary.
Important Note: Always use sharp, clean pruning shears to avoid damaging the plant.
It's always a good idea to consult a local gardening expert or your local nursery for advice on the best time to prune your specific viburnum variety.
