It has dark green foliage which emerges green in spring. The glossy oval leaves remain dark green throughout the winter. David Viburnum will grow to be about 4 feet tall at maturity, with a spread of 4 feet. It tends to fill out right to the ground and therefore doesn’t necessarily require facer plants in front. Viburnums are mostly moderate- to fast-growing plants. They can grow from 1 foot to more than 2 feet per year. Compact species and cultivars may be slower growing.Viburnum sizes vary: Common species grow 5-12 feet tall, depending on type. Optimal growth requires nutrient-rich soil, consistent moisture, and full sun exposure. Fast-growing varieties reach maturity in 3-5 years; slower ones take 5-10 years.Space anywhere from 3 to 8 feet apart depending on species and desired hedging vs. V. Viburnums prefer well-drained, fertile soils; many species adapt to a wide pH range and tolerate some clay.Viburnum sizes vary: Common species grow 5-12 feet tall, depending on type.

Is Viburnum davidii fast growing?
Viburnum davidii is slow growing and therefore requires minimal pruning. To retain a neat and dome-like shape, prune back to strong stems or the base of the plant after flowering. Also remove any diseased or damaged shoots to maintain a healthy plant. Typically, viburnum shrubs should be trimmed back about a third of their size each year. Most pruning is done for shaping purposes only.Pruning your viburnum helps to promote a well-branched shrub that has a denser growth habit. Light pruning can be performed any time throughout the growing season, but late winter or early spring is the best time to complete a hard pruning if needed.Viburnums can be pruned during their dormant season (late winter) and/or after they flower in late summer. All produce flower buds starting in late summer that will bloom the following spring. If live branches are removed during that window, those cuts will also remove potential flowers.Trees and Shrubs Are Dormant in Winter You’ll do less damage now when you prune, shape and thin your deciduous plants than if you had at it in their prime growing months. Those fresh pruning cuts you make heal faster during the dormant season — and are less likely to attract insects, which can carry diseases.As a rule of thumb, at each pruning, remove no more than one-third of a shrub or tree. Over-pruning = risk of shock or overreaction. Removing more risks sending the plant into shock or promoting overly vigorous growth at the site of the cut, which defeats the purpose of pruning. Do less if plant is compromised.
