Viburnum odoratissimum is a popular ornamental shrub that is known for its glossy, dark green leaves and fragrant white flowers. It is a versatile plant that can be used as a hedge, a specimen plant, or in mixed borders. However, before deciding to add this plant to your garden, it is important to consider how big it can grow. In this article, we will explore the growth habit of Viburnum odoratissimum and provide tips on how to manage its size.
Growth Habit of Viburnum Odoratissimum
Viburnum odoratissimum is a large evergreen shrub that can grow up to 20 feet tall and 15 feet wide in ideal conditions. However, in most home landscapes, it typically reaches a mature height of 8-12 feet and a spread of 6-10 feet. The plant has a dense, rounded growth habit and is often used as a hedge or screen plant.
Factors that Affect the Growth of Viburnum Odoratissimum
Several factors can affect the growth of Viburnum odoratissimum, including:
Viburnum odoratissimum thrives in warm, humid climates and is hardy in USDA zones 8-10. In colder climates, it may suffer from frost damage or dieback.
The plant prefers well-draining, fertile soil that is rich in organic matter. It can tolerate a range of soil types, including sand, loam, and clay.
Viburnum odoratissimum grows best in partial shade to full sun. In full shade, it may become leggy and produce fewer flowers.
The plant requires regular watering to establish and grow but can tolerate periods of drought once established.
Viburnum odoratissimum benefits from regular applications of fertilizer during the growing season. A balanced, slow-release fertilizer is recommended.
Tips for Managing the Size of Viburnum Odoratissimum
If left unchecked, Viburnum odoratissimum can quickly outgrow its space and become difficult to manage. Here are some tips for keeping it under control:
Regular pruning is essential for maintaining the size and shape of Viburnum odoratissimum. The plant can be pruned anytime from late winter to early spring before new growth begins. Use sharp, clean tools to make clean cuts and avoid damaging the plant.
When planting Viburnum odoratissimum as a hedge, it is important to train it early on to encourage bushy growth and a compact form. This can be done by selectively pruning the plant to encourage branching and a dense habit.
- Root pruning:
If the plant has outgrown its space, root pruning may be necessary to keep it under control. This involves severing the roots around the plant with a sharp spade to limit its size.
- Rejuvenation pruning:
If Viburnum odoratissimum has become overgrown and unsightly, it can be rejuvenated by severe pruning. This involves cutting the plant back to a few inches above the ground and allowing it to regrow.
- Planting location:
Before planting Viburnum odoratissimum, consider its eventual size and choose a location that will accommodate its growth. Avoid planting it too close to buildings or other structures that may restrict its size.
In conclusion, Viburnum odoratissimum is a beautiful and versatile plant that can add interest and texture to any garden. However, it is important to consider its size and growth habit before adding it to your landscape. By understanding the factors that affect its growth and implementing the right management techniques, you can keep it under control and ensure that it remains a beautiful addition to your garden.
