Growth Habits and Pruning Techniques
Bougainvillea exhibits diverse growth habits and can be shaped according to the desired form. It possesses the ability to grow as a small pot plant, a sizeable tree, a climber on walls or trellises, and even as bonsai or topiary. When grown as a climber or on trellises, Bougainvillea requires regular pruning to promote a neat and well-maintained appearance. Pruning not only helps control the plant’s size but also encourages branching, leading to a more robust and lush growth.
The best time to prune Bougainvillea is during late winter or early spring before the start of the growing season. This timing allows for the removal of dead, damaged, or diseased branches, as well as the trimming back of mature branches to promote bushier growth. Regular pruning also helps remove excessive or wayward growth, ensuring that the plant maintains its desired shape and form.
In addition to training on trellises, Bougainvillea’s complex branching can be utilized to shape it into beautiful bonsai or topiary forms. The intricate patterns and graceful shapes that can be created using the plant’s branching structure make it an excellent candidate for these artistic forms.
