How Do You Prune a Snowball Viburnum Bush?
Prune a snowball viburnum bush by sterilizing the equipment, cutting off flowers and cutting back the older branches before the fall. To complete this project, you need bleach, a bowl of water, two clean cloths and pruning shears.
Sanitize the pruning shears
Pour a cap full of bleach in a bowl of water. Soak the clean cloth in the mixture, and wring out the excess water. Wipe off the pruning shears with the cloth.
Remove flowers when they are no longer in bloom
Use the pruning shears to cut off the flowers from the bush after they fade. Get as close as you can to the bulb of the flower, and then cut back the shoots of the flower about one-third down the branch. Make a small cut in the side of these branches to encourage new branches to grow.
Cut off older branches
Cut up to one-third of the oldest branches down to the ground to encourage growth and renew the bush.
Look for new branches in the ground
Look for new growth on the ground while pruning, and cut these down to the ground. Look for new branches that shoot up out of the ground for some time after pruning, and cut them back if you don’t want the bush to spread.
Sanitize the pruning shears again
Wipe down the pruning shears with the bleach water when you are finished. Rinse off the bleach water, and let the shears dry completely.
