Methods for promoting the flowering of bougainvillea in autumn

Bougainvillea is a particularly industrious flower that can bloom in both spring and autumn, but if you want it to bloom successfully in autumn, you must do a good job of promoting flowering. Here is an introduction to the method of promoting flowering of bougainvillea in autumn.

1. Adequate lighting

Bougainvillea is a positive flower, which means it likes light. If you want Bougainvillea to bloom more and more frequently, first of all, the maintenance environment must have sufficient light. If there is a lack of sunlight at home, the amount of light that Bougainvillea is exposed to will be reduced, which will definitely affect its flowering. After entering autumn, Bougainvillea enters its peak growth season, and at this time it begins to differentiate flower buds and bloom. When caring for it, you need to expose it to the sun as much as possible. Only by ensuring sufficient light can the plant convert more nutrients to grow and bloom.

2. Potassium dihydrogen phosphate

Bougainvillea has been growing branches and leaves all the time, and in fact, there is no lack of nitrogen in its potting soil. What you need to do at this time is to use potassium dihydrogen phosphate. Potassium dihydrogen phosphate only contains phosphorus and potassium, but no nitrogen. After using it, it can slow down the growth of its branches and at the same time it can quickly differentiate flower buds.

3. Pruning branches

After spraying potassium dihydrogen phosphate, you need to trim the branches. The pruning method is relatively simple. If the new buds grow less than five centimeters, do not trim this bud point. As long as the new branches are more than five centimeters long, we need to prune them. Just keep four to six leaves from the bottom where the buds emerge.

4. Control water to promote flowering

If there is too much water, Bougainvillea will grow vigorously but not bloom. At this time, we need to control water to promote flowering. The so-called water control is to ensure that the lighting time is no less than six hours. Move it directly under the sun. If you want to water the soil in the pot, wait until the soil in the entire pot is completely dry and the leaves become slightly soft before watering it. Water it directly. After watering, let the soil dry again within one to two days, then water it again. Continuously repeat this process, which will help control water.

5. Supplement phosphorus fertilizer

Bougainvillea also needs to be supplemented with phosphorus fertilizer when it is blooming. Just choose phosphorus fertilizer with high phosphorus content after the flowers grow, such as Huaduoduo No. 2, and apply it once every 10 to 15 days. This way there will be no shortage of it, and it can ensure that it will bloom for one or two months at a time.

That’s it
