Foliage flowers shed more leaves and flowers at flowering stage, so they need to be trimmed after flowering. Potted plants are often trimmed into round-headed crowns or tied into other shapes, which require many branches and dense flowers to form a gorgeous crown.

The ground planting must set up a bracket to make it climb on the shelf. We should always pay attention to pinching new branches to form short and clustered plants. After changing pots, prune some over-dense branches, overgrown branches, dead branches and insect branches to promote more new branches. From July to August, the bougainvillea should be picked to control its growth, so as to promote the formation of flower buds and vigorous flowering. 5 ~ 6-year-old plants need to be cut short or re-sheared and updated once.
