Bougainvillea is a flower that blooms frequently, with most varieties blooming multiple times a year, especially in spring and autumn. Now that it has entered autumn, with enhanced care and management, it can bloom again and grow flower buds.
Bougainvillea is not afraid of heat or direct sunlight and will continue to grow branches even in the hot summer, with some even blooming. If you want it to continue blooming in autumn, you should prune it in early autumn to encourage the plant to produce more new branches for flowering.
Pruning after autumn
After growing through a summer, Bougainvillea branches can become very tangled, not only affecting the beauty of the plant shape but also consuming a lot of nutrients, which can affect the plant's ability to produce new flowering branches. After autumn arrives, simply prune these excessive growth branches and then supplement nutrients. After new branches grow, it can produce flower buds and bloom again.
When pruning Bougainvillea in autumn, do not prune too harshly. Mainly remove the thin and small branches, thin out the dense ones, remove the inner branches, and剪掉 the branches that grow upwards. For those branches that are tall and long due to excessive growth, just cut them off directly. After pruning, the plant will sprout new buds from the lower bud points.
Proper watering
Bougainvillea is a drought-tolerant plant, and the drier the potting soil, the easier it is to bloom. However, after pruning in autumn, it should not be allowed to become too dry. Keep the soil moist and water thoroughly when the soil dries out to encourage the plant to grow new branches as soon as possible.
After new branches grow, it is necessary to control watering appropriately to inhibit branch growth and encourage the growth of flower buds.

Autumn is the peak growing season for Bougainvillea, and nutrients should be supplied adequately. After pruning the branches, start applying some dilute fertilizer every ten to fifteen days to ensure sufficient nutrients, which will help the plant grow new branches quickly and make the branches thicker.
After the plant has grown new branches, start supplementing with phosphorus and potassium fertilizer, which can promote bud formation and flowering. You can apply monopotassium phosphate once a week, diluted to a ratio of 1:1000, and pour it directly into the pot until flower buds appear at the branch tips before stopping the fertilizer.
