About soil condition, (Viburnum opulus compactum) prefers rich, organic soils that are well-drained, but it is tolerant of a wide range of soil conditions including heavy clay. It also prefers full sun to partial shade, but it is tolerant of full shade as well.
So, like the other viburnums, the compactum variety requires full sun to partial shade in order to thrive. It can tolerate a wide range of soils as long as the ground is well-drained, and itÂ’s even tolerant of clay. This shrub is also salt-tolerant, making it a good choice for seaside gardens.
The temperature condition of the Viburnum opulus compactum is optimum at around 68 degrees Fahrenheit. However, it can survive in a range of temperatures, from 50 to 86 degrees Fahrenheit. It is important to keep the plant in an environment that is not too hot or too cold, as this can damage the leaves and flowers.
Ideal humidity condition for this plant is 50% or less. The plant does best in bright indirect sunlight but can also tolerate partial sun. It is a good plant for beginners as it is very easy to care for.
Regarding fertilizer, usually the plant doesn't need much. A light feeding in the spring is all that is necessary. If you want to use a fertilizer, use a balanced fertilizer such as 10-10-10. As for the roots, they are fine as long as they are not root-bound.
Pruning viburnum opulus compactum is best done in late winter or early spring, before new growth begins. It is a good idea to prune out any dead or diseased wood, as well as any crossing or rubbing branches. You can also prune to shape the plant, or to reduce its size if necessary.
Propagation is by softwood cuttings in late spring or early summer. The best time to take the cuttings is when the plant is beginning to put on new growth. The cuttings should be about 4-6 inches long and should be taken from the tips of the branches. Cuttings can be rooted in a pot of sand or peat moss. The pot should be kept moist and in a location that has bright, indirect light. After the cuttings have rooted, they can be transplanted into pots or into the ground.
Usually, the plant growth rate is about 1 foot per year. However, some plants may grow more quickly, while others may grow more slowly. The specific growth rate of your plant will depend on several factors, including the type of soil it is grown in, the amount of sunlight it receives, and the amount of water it gets.
Common problems for this kind of plant include powdery mildew, leaf spot, and rust. These can all be treated with fungicides. However, it is best to prevent these problems from occurring in the first place by keeping the plant healthy and stress-free.
