Caring for Viburnum

The care information provided in this section represents the kind of practical advice is available for all the plants in this web site if you subscribe to the monthly customized newsletter Yardener’s Advisor.

Watering
Viburnums do not usually need watering except when they're first planted, in time of drought, or in late fall before the ground freezes for the winter. If you do water, give your plants 1 gallon of water twice a week or run your drip irrigation system or sprinkler for 20 to 30 minutes twice a week. Older shrubs need watering only during severe drought.
For more information see file on About Watering Equipment.

Fertilizing
These shrubs need only one yearly application of bagged sludge, a granular fertilizer with a slow release form of nitrogen, or compost. In the fall, spread a 10-10-10 fertilizer on the soil to 1-1/2 feet beyond the tips of the branches (drip line). You may wish to supplement the fall feeding with 2 or 3 monthly snacks in late spring and early summer. Use a light side dressing of granular fertilizer or apply a foliar spray of dilute liquid fertilizer over all the leaves of the plant.
For more information see file About Fertilizers.

Consider Plant Growth Activators
There are on the market a growing number of products that will help your plants become healthier, more drought resistant, more disease resistant, and even more insect resistant. These products are generally easy to use and not terribly expensive. If you want to give your plants some oomph, check out New Technology In Plant Growth Activators

Mulching
Viburnums do best when they have a 2- to 4-inch layer of organic mulch over their root zone all season long. Keep the mulch about 6 inches away from the trunk to avoid decay and rodent damage. Use chopped leaves, pine needles or wood chips to mulch viburnum. Avoid mulching with un-chopped leaves because they mat together, preventing water from getting into the soil. Peat moss makes poor mulch, because it draws water from the soil like a wick and is difficult to rewet when dry.
For more information see file on Using Mulch.

Pruning/Grooming
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. For a more formal effect, it is possible to train Viburnums to a single trunk. Choose the healthiest and most upright stem when young and keep side shoots pinched until it reaches the height you want. Then allow the plant to branch from the top.
