About soil condition, (viburnum opulus) prefers well-drained, slightly acidic soils, but it is adaptable to other soil types. It will not tolerate wet, poorly-drained soils. If the soil is too alkaline, it can be amended with the addition of sulfur.
Not too different with other viburnums, the American cranberrybush (Viburnum opulus) needs full sun to partial shade to thrive. It's a medium to large deciduous shrub that can reach 15 feet tall and wide, making it a good choice for mixed borders and hedges. The foliage is dark green and glossy, and the branches are covered with clusters of white flowers in spring, followed by edible red berries in fall.
The temperature condition of the Viburnum opulus is cool to cold. This plant can tolerate temperatures as low as -30 degrees Celsius. It is also tolerant of heat and can survive in temperatures as high as 35 degrees Celsius.
Ideal humidity condition for this plant is 50% or less, as too much humidity can encourage fungal problems. Viburnum opulus does best in bright, indirect sunlight but can tolerate some direct sun if the humidity is low. When the humidity is too high, the leaves of the plant can develop brown spots.
Regarding fertilizer, usually the plant does not need much. If you want to give it some, you can use a low-nitrogen fertilizer in the spring. Just be sure not to overdo it. As for the roots, they are relatively deep and fibrous, so you shouldn't have too much trouble with them. Just be sure to water the plant deeply and regularly, especially during hot, dry periods.
Pruning your viburnum opulus is important to maintain its shape and size. You should do this in early spring, before the plant begins to produce new growth. First, remove any dead or damaged branches. Then, cut back any overgrown branches to keep the plant within its desired size and shape.
Propagation for viburnum opulus is typically done through softwood cuttings taken from new growth in late spring or early summer. The cuttings should be 4-6 inches long and taken from the outermost portion of the branch. Cuttings should be taken from healthy, disease-free plants. After taking the cuttings, remove the bottom leaves and dip the cut end into rooting hormone. Plant the cuttings in a pot filled with a well-drained, sterile potting mix. Place the pot in a location that receives indirect light and keep the soil moist. Cuttings should root within 4-6 weeks. Once the cuttings have rooted, they can be transplanted into individual pots filled with a well-drained potting mix.
Usually, the plant growth rate is in the range of 24 to 36 inches (60 to 90 cm) per year. However, some varieties have been known to grow as much as 50 inches (125 cm) in a year. The plant is fast-growing and can quickly become overgrown if not properly managed.
Common problems for this kind of plant are powdery mildew, rust, and leaf spot. These can all be treated with fungicides. If you see any of these problems, remove affected leaves and dispose of them. Do not compost them.
