Training nandina, also known as heavenly bamboo, involves guiding its growth to achieve a desired shape or size. Proper training enhances its aesthetic appeal and health, making it a valuable addition to gardens and landscapes.
Understanding Nandina Growth Habits
Nandina is a versatile shrub that can grow up to 6 feet tall and wide. It features delicate, feathery foliage and vibrant berries in the fall. Its natural growth habit is bushy and upright, but with proper training, you can control its shape and size.
Tools and Materials Needed
- Pruning shears
- Garden ties or soft twine
- Support stakes (if needed)
- Gloves
Steps to Train Nandina
1. Prune for Shape and Health
Begin by removing any dead, damaged, or crossing branches. Prune to encourage a central leader or to promote a more open, airy structure. Regular pruning helps maintain the desired size and shape.
2. Use Supports to Guide Growth
If you want to train nandina to grow in a specific direction or form, use garden ties or soft twine to gently secure branches to support stakes or espalier wires. Be careful not to tie too tightly to avoid damaging the plant.
3. Train Gradually
Adjust ties periodically to prevent girdling and to accommodate new growth. Gradually guide branches over several seasons for a natural, well-shaped appearance.
Maintenance Tips
Consistent maintenance is key to successful training. Regularly prune to remove unwanted growth and to maintain the shape. Fertilize in early spring to promote healthy growth and better response to training efforts.
Common Training Goals
- Creating a hedge or screen
- Controlling height and width
- Training into a specific shape, such as a topiary
- Encouraging bushy or upright growth
By understanding nandina’s growth habits and applying proper training techniques, you can achieve a beautiful, healthy plant that enhances your landscape and meets your aesthetic goals.
