When the temperature is too high in summer, the leaves and new lateral branches of bougainvillea will grow faster, which will make the gaps between branches crowded and have poor air permeability, which will affect the healthy growth of bougainvillea and consume too much nutrients. At this time, it is necessary to prune too dense branches in time to maintain a ventilated environment.
If the temperature is too low in winter, it will slow down the growth of bougainvillea. If dead leaves and weak branches are found, they should be cut off in time, and the residual leaves and dead leaves should also be removed. These seemingly useless branches and leaves will absorb the nutrition of bougainvillea. At this time, if the nutrients are insufficient, it will lead to slow flower bud differentiation, slow flower bud formation and late flowering. Before the flower bud formation period, a small amount of phosphorus and potassium fertilizer can be applied to promote flower bud differentiation.
Pruning the weak branches, residual flowers and broken leaves in time after bougainvillea not only affects the sense of appreciation, but also wastes the nutrients of bougainvillea, so it is necessary to remove the residual flowers and broken leaves in time. At the same time, nitrogen and potassium fertilizer should be applied to bougainvillea once to supplement the nutrients consumed during flowering, and it can also promote the emergence of new buds.
Summary: bougainvillea can prune branches all year round. After pruning in spring and autumn, flowers should be supplemented with nutrition in time. Pruning branches regularly will make bougainvillea grow more vigorously!
Through our introduction, I believe everyone has a deeper understanding of when bougainvillea is best pruned and when it is most suitable.
