Are viburnum slow-growing?
Yes, viburnums are slow-growing. They do not usually grow more than 2 feet in a year. They grow most in the spring to fall. Their growth reduces in the winter as their metabolism becomes slower in the cold.
Some viburnums are relatively fast-growing than other species, although you still can’t expect a lot of growth from fast growers. All you can do is take proper care of the plants.
Viburnums are very hardy types of plants, needing very little care. Slight acidic soil, a proper drainage system, and good sunlight are required for optimum growth.
After planting viburnum, they need some extra care. Water the newly planted plants every day for a month. After the plant settles down, watering once a month will be enough. They can live in low-fertilizer soil, but fertilizing three times a year is needed for their best growth.
The full-day sun is best for their growth. They grow faster and bloom more if they get proper sunlight. It is possible to plant them in partial shade.

How can I make my viburnum grow faster?
Viburnums are relatively easy to grow and care for compared with other ornamental plants. If a viburnum plant gets suitable conditions and care, it can grow about 24 inches a year. Here are some tips for faster growth.
Spacing is essential for the faster growth of the viburnum. At least 4 feet of distance is needed for each viburnum plant. Some viburnums grow wider than other species. You can either prune the plant or provide more space for them.
Spacing is needed for proper nutrient absorption. If you plant more plants in a small space, they will compete for light, space, and nutrients, leading to poor growth.
The Viburnum plant usually does not need a lot of water. Water the plants once a month or when the soil lacks moisture. Young plants need regular watering for a few months.
The more sun viburnum gets, the better it grows. They also grow decently in partial shade. If you are fencing with viburnum, you can plant them in the shade. The viburnum leaves look great when they grow in the shade.
The problem is they don’t bloom without direct sun.
Any type of moderately fertilized soil is suitable for viburnum. For best growth, apply fertilizer three times a year. They require a balanced fertilizer with nitrogen and phosphorus.
How long does it take for viburnum to reach maturity?
Usually, most viburnums need three years to reach maturity. Smaller species of viburnums reach maturity faster, while larger species like sweet viburnum can take a bit more time to mature.
When a viburnum gets to 6 feet, you can call it a mature plant. If your viburnum plants are older than three years but still do not look mature, the plant may not get the proper nutrients to grow.
Most of the viburnums are slow growers and grow 1-2 feet on average. The growth rate of viburnum depends more on the condition such as soil type, sunlight, water availability, and drainage. Once a viburnum plant matures, it becomes pretty hardy and stable in different situations.
