Bougainvillea leaf drop and flower drop: causes and solutions that can promote longer blooming and evergreen leaves

Bougainvillea has a long blooming period and comes in many colors, making it very suitable for growing. However, during cultivation, various situations of leaf drop and flower drop always occur. What causes them? And how should they be handled?
1. Human moving
Bougainvillea flowers are relatively fragile. If you frequently move it during the blooming period, or if there is strong wind and heavy rain, it will cause leaf drop and flower drop. It is best to fix the flowerpot in one place, preferably a place sheltered from wind and rain with plenty of sunlight.
2. Improper watering
Other flowers need watering when they bloom, but bougainvillea should be watered as little as possible during the blooming period, so that the blooming period will be a bit longer. Watering will cause the flowers to drop quickly. If during the blooming period you find the branches and leaves wilting, you can use a spray bottle to increase humidity in a small area.
3. Bougainvillea blooming period
Bougainvillea normally blooms in October to November, and flower bud differentiation occurs in August to September. To make bougainvillea bloom more, you can use a small trick, which is controlling water to promote flower bud differentiation. During the blooming period, more phosphorus fertilizer needs to be applied to extend the bougainvillea blooming period.
4. Improper fertilizing
When bougainvillea drops leaves and flowers due to excessive fertilizing, you also need to think about whether you have recently applied too much fertilizer. Too much fertilizer or the wrong fertilizer will cause bougainvillea root burn, plant wilting, yellowing leaves, and flower drop.
5. Insufficient light
Bougainvillea is a sun-loving plant, and it needs more than 9 hours of sunlight every day, so that the leaves are dense and it blooms more. Especially during the blooming period, if this requirement is not met, it will drop flowers and leaves!
6. Solutions for bougainvillea leaf drop and flower drop
Supplement light:Anyway, bougainvillea is not afraid of sun, and the more sun it gets, the more beautiful it becomes. Flower lovers should not be stingy with sunlight. Just put it under the light as much as possible, and bougainvillea will return to normal.
Prune dead leaves:When bougainvillea drops leaves, the plant will have yellow leaves. At this time, cut off the yellow leaves and keep the branches. After sprouting, cut off the dead branches.
Control fertilizing:When fertilizing, choose fully decomposed organic fertilizer and stick to the principle of light fertilizer applied frequently, to avoid root burn and leaf drop.
Control watering:Insufficient watering or excessive watering will both cause leaf drop, so water according to the season. In summer, water once in the morning and once in the evening every day. In winter, water once every 3 to 5 days. Both can avoid leaf drop.
