Willowwood Viburnum Viburnum × rhytidophylloides 'Willowwood'

Water

The Leatherleaf Viburnum should be watered deeply and thoroughly, ensuring the root zone is moistened, which can be achieved with approximately 1 to 2 gallons of water for a newly planted shrub, depending on the plant size and soil conditions. It's important to water the plant once a week during its first growing season to establish a deep, extensive root system. During the second growing season, reduce watering frequency to every other week, unless there are periods of extreme heat or drought. Mature plants will require less frequent watering, relying on rainfall with supplemental water only during prolonged dry spells.

Light

Leatherleaf Viburnum thrives best in full sun to partial shade, with at least 4 to 6 hours of direct sunlight each day. An ideal spot would be one where the morning sun encourages the drying of dew on leaves, thus reducing the risk of diseases, while providing some afternoon shade in areas with hot summers to prevent leaf scorch.

Temperature

Leatherleaf Viburnum is hardy and can tolerate a broad range of temperatures, thriving in zones 5 to 8. The plant can survive minimum temperatures down to -20°F and is comfortable in the maximum summer temperatures of up to 100°F, with ideal growth temperatures ranging between 60°F and 80°F.

Pruning

Prune Leatherleaf Viburnum to maintain shape and size, promote healthy growth, and remove dead or diseased wood. The best time for pruning is immediately after flowering in late spring or early summer, as this shrub flowers on old growth. Pruning should be done annually or as necessary to remove any crossed branches and to maintain the desired shape.

Cleaning

As needed

Soil

Willowwood Viburnum thrives in well-drained, fertile soil that's rich in organic matter. A soil mix of loam, peat, and sand in equal parts is ideal, maintaining a slightly acidic to neutral pH between 5.5 and 7.0.

Repotting

Willowwood Viburnum is typically planted in-ground and does not require frequent repotting. If grown in a container, repot every 2-3 years to refresh the soil and accommodate root growth.

Humidity & Misting

Willowwood Viburnum prefers average humidity levels but is adaptable to various conditions. It does not have specific humidity requirements but generally thrives in outdoor environments with natural humidity.

Suitable locations

• Indoor

  Ensure bright indirect light, moderate water, and good air circulation.

• Outdoor

  Plant in well-draining soil, full sun to partial shade, water regularly.

• Hardiness zone

  5-8 USDA

Life cycle

The common name for Viburnum × rhytidophylloides 'Willowwood' is Willowwood Viburnum. Its life cycle begins with germination from seed, although it is often propagated by cuttings for uniformity. After rooting, the young sapling grows by developing a strong root system and foliage until it reaches the juvenile stage. As it matures, the plant enters a growth phase characterized by the development of its defining features: large, leathery leaves and clusters of white flowers that typically bloom in spring. Following pollination, the flowers produce berry-like drupes that transition from red to black when ripe, which can be dispersed by birds, leading to new plants if conditions are favorable. Eventually, the Willowwood Viburnum reaches maturity, completing its cycle and may continue to reproduce annually for many years, with proper care and favorable conditions.

  Spring-Early Summer

• The most popular method of propagation for the Willowwood viburnum is through semi-hardwood cuttings. This technique is typically done in late summer. To propagate, select a healthy, non-flowering stem that has started to mature but is not yet fully woody. Cut a section of the stem about 4-6 inches (10-15 cm) long, making sure the cutting has at least two sets of leaves. Remove the leaves from the lower half of the cutting to prevent decay and excess moisture loss. Dip the cut end into a rooting hormone to encourage root development. Plant the cutting in a pot filled with a mixture of peat and perlite, making sure at least one set of leaves is above the surface. Water the cutting and then cover the pot with a plastic bag to maintain high humidity around it. Place the pot in a bright area without direct sunlight until roots develop, which usually takes several weeks. Once rooted, the cuttings can be transferred to individual pots and eventually planted outdoors when they are strong enough to survive the elements.
