Care of Viburnum Outdoor Plants


Because of their low-maintenance nature, viburnums are popular residential landscape plants. Generally used as an ornamental, depending upon species, the viburnum will grow from 2 to 30 feet in height and bloom with white, fragrant flowers. Fruit appears in the fall and winter. Viburnum will grow in a variety of soil types, is resistant to most diseases and pests and seldom needs pruning.

Step 1

Water the viburnum when the top 2 inches of soil is dry. Check the soil frequently during periods of extreme heat as you may need to water more often.

Step 2

Fertilize the viburnum in the spring with a 5-10-5 formula at the rate suggested on the package.

Step 3

Add a 3-inch layer of mulch to the soil around the base of the viburnum. Don't allow the mulch to touch the plant's bark and spread it out as wide as the shrub.

Step 4

Prune in the spring but cutting off old or diseased stems. Cut them to the soil.

Step 5

Inspect the viburnum for fungal diseases. These will generally appear as spots on the foliage. Remove infected foliage from the plant and the garden bed. Management of fungal diseases includes the use of fungicides containing chlorothalonil, thiophanate-methyl, myclobutanil or mancozeb, according to agricultural extension agents with Clemson University. Apply the fungicide, according to label directions, at the first sign of infection and repeat the application every two weeks until the disease is controlled.

Tips and Warnings

  • Fungicides and fertilizers may contain toxic chemicals. Read and follow all label directions, wear protective clothing during application and store the chemicals out of the reach of children and pets.
