How to Prune and Fertilize Bougainvillea After Blooming for Best Results
Today's article introduces how to prune and fertilize bougainvillea after blooming for the best results, and we will explore this together.
Bougainvillea is one of the most common flowering plants in homes. It is bought to enjoy the flowers, but often after blooming, when we take care of it, it will only grow leaves and not flowers. In fact, pruning is crucial.
If you prune properly and handle it reasonably, it will continue to bloom. If you cut incorrectly, it will result in fewer or even no flowers.
After most bougainvillea finish blooming, many enthusiasts will choose to剪 (cut) the top appropriately, or just剪 (cut) off the spent flower stalks. However, this is not correct.
Because during the blooming process, the branches grow longer and longer, and eventually, the whole plant becomes very large. The distance for the bottom roots to absorb nutrients increases.
Moreover, blooming later occurs from flower buds growing on the top of the branches, and even if we fertilize, the distance for nutrient transmission is too great, resulting in very little nutrient reaching the top, which can cause fewer flowers or even no flowers to grow.

1. Pruning
When pruning bougainvillea after blooming, it is necessary to select the right tools. Ensure that the pruning wounds are smooth and even, and it is best to use a sharp pair of scissors for pruning.

After pruning, you can spray the plant with a carbendazim solution.
2. Fertilizing
To fertilize bougainvillea, it is necessary to supplement with phosphorus and potassium-based fertilizers, and the method of fertilization should be chosen based on the soil's condition.
When the soil is dark, the fertilizer can be diluted and poured into the plant. When the soil is white or light in color, the fertilizer should be added directly to the soil.
When fertilizing bougainvillea, it is also necessary to pay attention to the amount of fertilizer. If fertilizer damage occurs, water should be poured into the soil to dilute the fertilizer content. In severe cases of fertilizer damage, the bougainvillea must be dug out of the soil, and its roots should be rinsed clean with water.
【Summary】
After bougainvillea blooms, it is important to prune promptly. Cut off the spent flowers on the branches, and also剪 (cut) the flowering branches shorter.剪 (Cut) off the diseased and weak branches, and also thin out the dense branches.
Besides, bougainvillea produces many flowers and has a very long flowering period, consuming a lot of nutrients. After blooming, it is necessary to apply a top dressing promptly, using decomposed organic fertilizer and chemical fertilizers.
