Bougainvillea, also known as paperflower, is loved by flower enthusiasts for its bright colors and long flowering period. Potted bougainvillea is an excellent choice for home decoration. To ensure the vigorous growth of bougainvillea bonsai, pruning is an essential step. This article will introduce you to the pruning techniques for bougainvillea bonsai, helping your bougainvillea to rejuvenate.
Pruning TimeBougainvillea is usually pruned in spring and autumn. Spring pruning promotes the growth of new buds, while autumn pruning helps the bougainvillea to survive the winter. Before pruning, ensure that the bougainvillea is growing vigorously and free from diseases and pests.
Pruning ToolsWhen pruning bougainvillea bonsai, use sharp, rust-free scissors or pruning shears. The length of the scissors should be suitable for the pruning area, as being too long or too short will affect the pruning results.
Pruning Principles1. Retain Main Branches: When pruning, retain the main branches of the bougainvillea to maintain its overall shape. The length of the main branches is generally controlled between 20-30 cm. Too many or too few will affect the growth of the bougainvillea.
2. Remove Sick and Weak Branches: During pruning, remove sick, weak, dead, intersecting, and inward branches. These branches consume the nutrients of the bougainvillea and affect its growth.
3. Moderate Thinning: For excessively dense branches, moderate thinning should be done to facilitate ventilation and lighting, reducing the occurrence of diseases and pests.
4. Maintain Shape: According to personal preference, prune to create different shapes such as round, spherical, cascading, etc.
