Vibrum is a genus of flowering plants belonging to the family Fabaceae, which includes such familiar members as tomatoes, potatoes, eggplants and peppers. These plants are often referred to collectively as “vegetable” or “fruit trees.” Some species have been cultivated for food, medicine and other uses; others are ornamental. Most viburnums are native to warm climates, but there are a few that grow naturally in temperate regions.
Some of these species may be grown commercially for their fruit and seeds (especially when they’re not too cold), while others may require little attention if kept well watered. Others will need special care to produce viable seedlings, especially if they’re young or have poor drainage.
A few species are invasive and regarded as noxious weeds in certain areas (V. dentatum, for example). If you live in a medium or high-risk area for such plants, you should take steps to prevent them from spreading if you want to grow them.
While most viburnums will grow well in the ground if given enough space, they may also be grown as trees rather than shrubs. They can be espaliered along a wall, which is useful for providing an attractive screen or windbreak. They can also be trained into fans and other decorative shapes if you have the patience and time to do it.
Most viburnums grow best in a slightly acidic soil that has been enriched with plenty of organic matter, but they should not be allowed to become waterlogged. They should not be planted in toxic or excessively salty soils.
They will grow well under a wide range of conditions, but most species prefer a sunny position with protection from strong winds and frost. Although most viburnums can withstand brief frosts, they should be protected from prolonged cold and freezing conditions – temperatures below -10°C are regarded as dangerous. They should also be protected from strong winds, which can break branches and tear the shrub apart.
Cuttage is a genetic technique that involves taking a cutting from a plant, rooting it, and growing new plants from this rooted cutting. This is the most common way of propagating shrubs and trees.
Most viburnums can be easily propagated by cuttage (see right). The main exceptions to this are V. tinus and V. rafinesquianum, which have not been succesfully propagated by cuttage so far.
Cuttage, in general, works best on woody plants that produce many shoots and sprouts from the stump or roots. Soft-stemmed, herbaceous plants are generally much more difficult to propagate in this way.
The best time to take cuttings is during the dormant season (winter), and the easiest way is to use a saw to cut through thick stems close to the ground. The cutting should contain at least one node (joint) with leaves or buds, and may be dipped in a rooting hormone before being planted into perlite, vermiculite, or another medium in individual pots or containers.
Cuttings can also be taken from actively growing shoots in the springtime, although these tend to be more difficult to root.
Once rooted, the new plants may take a few years to grow to maturity, but they will make an attractive addition to any garden.
Viburnums should be planted in groups rather than alone, as this provides shelter for them and helps them look their best. Larger specimens can be planted at the corners of a property or at the center of a circular hedge, while smaller shrubs can be used to create accent plants in beds and borders.
Most species of viburnum can be mixed with most other plants. If there are any diseases or pests that are specific to the viburnums, I’ll discuss them later in this section.
The most important thing to know about viburnums is that they are generally pest- and disease-free plants. All but a few of the viburnums grow wild in their natural habitat, so they’ve had to evolve without human help. Many species have developed strong resistances to pests and diseases, so they rarely suffer from such attacks. However, there are a few circumstances where pests and diseases can trouble even the hardiest of plants.
These will be covered in the following sections.
I’ve found evidence that some people are allergic to the pollen of Viburnum tinus (sweet viburnum or laurustinus). If you suffer from hayfever or other allergies that affect your eyes, nose or throat, you should take care when planting laurustinus. Check with your doctor before planting it in your garden.
Some viburnums can cause problems if they are ingested in large quantities. Viburnum species such as the arrowwood (V. dentatum) are poisonous if eaten, and animals should not be allowed to browse on them. The seeds of other viburnums, such as the American cranberrybush (V.
trilobum) are edible, but considered very poor man’s food.
More Viburnum Care Details…
Most viburnums prefer moist soil, but should never be allowed to stand in water. During the hottest part of summer, they should be watered on a weekly basis, but increased watering may be required in areas that experience long periods of drought.
Viburnums can grow in a wide range of soil types, but all prefer soil that is rich in organic material. They also prefer soil that is loose and drains well. Viburnums will not grow well in soil that is constantly soggy or water-logged.
Many viburnums are so hardy they can grow in pure sand, though they will often look better and be healthier if given a fertile soil.
Soil pH appears to have little effect on viburnums. Most viburnums will grow in soil with a wide range of pH levels.
Viburnums are not heavy feeders. Many gardeners report success with using a balanced fertilizer in spring and again in the early fall. Other growers say a yearly application of fertilizer doesn’t do much for their viburnums.
As with many plants, it’s often a good idea to wait until the plant is a couple years old before adding any fertilizer at all.
