About soil condition, (viburnum opulus roseum) prefers rich, well-drained soils, but tolerates a wide range of soils as long as they are not waterlogged. It grows best in full sun, but can tolerate some shade.
Not too different with other viburnum species, the American cranberrybush (Viburnum opulusL.) should be planted in moist, humus-rich, well-drained soils in full sun to partial shade. Soil pH should be slightly acidic to neutral. The shrub will tolerate some shade, but flowering and fruit production may be reduced. Ample sun is needed for the formation of the showy fruits.
The temperature condition of the environment is an important factor to consider when growing the Viburnum opulus roseum. This plant prefers cool to cold temperatures and will not tolerate prolonged periods of heat. The ideal temperature range for this plant is between 50-60 degrees Fahrenheit. If the temperature gets too hot, the leaves of the plant will begin to wilt and the flowers will start to fade. If the temperature gets too cold, the plant will become dormant and the leaves will fall off.
Ideal humidity condition for this plant is 50%, meaning that the air around the plant should be neither too dry nor too wet. If the air is too dry, the leaves will begin to turn brown and crisp. If the air is too wet, the leaves will start to rot.
Mentioning fertilizer, usually the plant gets all the essential nutrients from the soil in which it is grown. However, if the soil is lacking in any of these nutrients, the plant will not be able to grow to its fullest potential. Viburnum opulus roseum, or guelder-rose, is a perfect example of a plant that responds well to fertilizer. This plant is a deciduous shrub that is native to Europe and Asia. It is grown for its beautiful white flowers that bloom in the spring and its bright red berries that appear in the fall. The guelder-rose is a relatively low-maintenance plant, but it will benefit from being fertilized once a year. The best time to fertilize this plant is in the spring, just before the new growth begins.
Pruning viburnum opulus roseum is best done in late winter or early spring before new growth begins. This plant responds well to pruning, so don't be afraid to cut back any wayward or overgrown branches. When pruning, always make clean, sharp cuts just above a bud or node.
Propagation is best done in early spring by rooting hardwood cuttings. Take 6-8 inch cuttings from last year's growth, remove the leaves from the bottom half of the cutting, and dip the cut end in rooting hormone. Plant the cuttings in a well-drained potting mix, water thoroughly, and place in a bright location out of direct sunlight. Keep the soil moist but not wet and in a few weeks, you should see new growth.
Usually, the plant growth rate studies have been conducted in Europe, where the species is native. Studies have shown that the species has a slow to moderate growth rate, with an average of 10-20 centimeters per year. However, there is variation among individual plants, with some plants growing much faster or slower than the average. The species is often used as an ornamental plant in gardens and parks, and its slow growth rate is generally considered to be an advantage in this context.
Common problems for this kind of plant are powdery mildew, canker, and leaf spot. For powdery mildew, try spraying the plant with a fungicide. For canker, prune out the affected branches. For leaf spot, remove the affected leaves and dispose of them.
