Whether you’re growing it as a houseplant or in your outdoor landscape, proper pruning is essential for maintaining its health and beauty. This comprehensive guide will provide you with all the information you need to prune bougainvillea like a pro.
Understanding Bougainvillea
Bougainvillea is a deciduous vine, meaning it loses its leaves during the winter months. It is hardy in USDA zones 9-11, but can also be grown as a container plant in cooler climates. Bougainvillea prefers full sun and well-drained soil.
Safety First: Protecting Yourself from Thorns
Many varieties of bougainvillea have sharp thorns, so it’s important to take precautions when pruning. Wear thick, leather gloves that cover your forearms and a long-sleeved shirt to prevent scratches.
When to Prune Bougainvillea
The best time to prune bougainvillea depends on how and where it is growing.
- Container plants in cool climates: Prune back in fall before moving indoors.
- Outdoor plants in zones 9-11: Prune in late winter/early spring when the plant is semi-dormant.
Pruning Techniques
- Remove dead or diseased wood: Cut out any branches that are brown, brittle, or have any signs of disease.
- Thin crowded branches: Remove any branches that are growing too close together to improve air circulation.
- Shape and train: Bougainvillea can be pruned into various shapes, such as a tree, shrub, or groundcover.
- Deadhead: Remove spent blooms to encourage new growth.
Pruning Bougainvillea in Different Growing Zones
- Zones 9-11: Prune heavily in late winter/early spring to control growth and encourage blooming.
