If the temperature is too high in summer, the leaves and newly grown lateral branches of bougainvillea will grow faster, which will make the gaps between branches crowded, 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 little phosphorus and potassium fertilizer can be used to promote the flower bud differentiation.
The weak branches, residual flowers and withered leaves of bougainvillea should be pruned in time after withering, which not only affects the appreciation, but also wastes the nutrients of bougainvillea, so the residual flowers and withered leaves should be removed 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.
conclusion: bougainvillea can prune branches all year round, and after pruning in spring and autumn, the flowers should be supplemented with nutrients 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 bougainvillea is most suitable for pruning.
