What to do if bougainvillea drops flowers and leaves

Why does bougainvillea drop its flowers?

Human factors

If the bougainvillea is frequently moved during its flowering period, or is exposed to heavy wind and rain, the flowers will fall off. Therefore, during the flowering period, repot the plant and place it in a fixed position, moving it to a place that is sheltered from wind and rain and has plenty of sunlight.

Improper watering

Try not to water the bougainvillea when it is in bloom, so that the flowering period will be longer. Watering during the flowering period will cause the flowers to fall off quickly, so be careful not to water when the bougainvillea is in bloom. If the branches and leaves wilt, you can spray appropriately to increase the humidity.

The normal flowering time of Bougainvillea is October-November, and flower bud differentiation is generally completed in August-September. In order to make Bougainvillea bloom more beautiful flowers, you can promote the differentiation of flower buds through proper water control, and apply more phosphorus fertilizer during its flowering period, which will help prolong the flowering period of Bougainvillea.

Fertilizer burn

Overfertilization or incorrect fertilizer selection will cause the roots of the bougainvillea to burn, the entire plant to wilt, the leaves to turn yellow, and the flowers to fall off.

Insufficient light

Bougainvillea loves sunlight and needs more than 9 hours of sunlight a day to ensure its lush branches and leaves and colorful flowers. If the light requirements are not met during the flowering period, the bougainvillea will grow abnormally and cause the flowers to fall.

What to do if bougainvillea leaves fall off

Bougainvillea is prone to losing leaves during the cultivation process. The reason is the same as the reason why Bougainvillea flowers fall. The editor will not elaborate here. Here I will introduce to you how to deal with Bougainvillea leaf falling!

Supplemental lighting

Bougainvillea is a sun-loving plant. If it is kept in a shaded environment for a long time, it will inevitably shed its leaves. At this time, the plant needs to be moved to the sun in time, and the bougainvillea will gradually recover after a period of time.

Control watering

Insufficient water supply in hot seasons or excessive watering in winter can easily cause leaf fall. Therefore, water the Bougainvillea in moderation. In summer, water it once in the morning and evening every day. In winter, reduce the frequency of watering appropriately, watering it once every 3 to 5 days, which can avoid the phenomenon of Bougainvillea leaf falling caused by improper watering.

Temperature control fertilization

The suitable temperature for the growth of Bougainvillea is 20-30℃. Too low or changing temperature will cause the leaves to fall off. Especially in winter, if you bring the plant indoors late, the leaves will fall to the ground. When applying fertilizer, choose well-rotted organic fertilizer and adhere to the principle of applying small amounts of fertilizer frequently to avoid burning the roots and causing leaves to fall.

Prune dead leaves

When bougainvillea sheds its leaves, the plant will have yellow leaves to varying degrees. At this time, the yellow leaves should be cut off, but the branches should be retained. Cut off the dead branches after they sprout again. It is normal for leaves to fall off during the seedling growth period or in winter. Just put it in a cool place and clean up the fallen leaves in time, and it will be fine after a while!
