Main Content Introduction: This article provides information on what to do when bougainvillea flowers drop during bloom and tips for making bougainvillea bloom abundantly. Let's delve into the details.
Bougainvillea has a long blooming period with diverse colors, making it very suitable for potted landscaping. However, during cultivation, it is common to encounter the problem of bougainvillea flowers and leaves dropping. So, why do bougainvillea flowers drop? What should we do when the leaves fall?
Why Do Bougainvillea Flowers Drop?
Human Factors
Frequent moving or heavy rain during the blooming period can cause flowers to fall. Therefore, during the blooming period, keep the pot in a fixed location, moving it to a windproof and rainproof area with ample sunlight.
Improper Watering
Try not to water the bougainvillea when it is blooming, as this will extend the blooming period. Watering during the blooming period will cause the flowers to fall quickly, so be careful not to water during this time. If the branches and leaves wilt, you can spray water to increase humidity.
The normal blooming period for bougainvillea is October to November, and bud differentiation usually completes in August to September. To make bougainvillea bloom more beautiful flowers, you can promote bud differentiation by controlling water intake appropriately, and applying phosphorus fertilizer during the blooming period can help extend the blooming period.
Root Burn from Fertilizing
Too much fertilizing or choosing the wrong type of fertilizer can cause root burn in bougainvillea, leading to wilting of the entire plant, yellowing of the leaves, and flower drop.
Inadequate Sunlight
Bougainvillea loves sunlight and requires more than 9 hours of sunlight per day to ensure lush growth and vibrant flowers. If the required sunlight is not met during the blooming period, it will lead to abnormal growth and cause flower drop.
What to Do When Bougainvillea Leaves Drop
Supplement Sunlight
Bougainvillea is a sun-loving plant, and if kept in a shaded environment for a long time, it will inevitably experience leaf drop. At this time, you should promptly move the plant to a sunny area, and after a period, the bougainvillea will gradually recover.
Control Watering
Inadequate water supply in hot weather or excessive watering in winter can easily cause leaf drop. Therefore, water the bougainvillea moderately, watering twice a day in the summer and reducing the frequency to once every 3 to 5 days in winter to avoid leaf drop caused by improper watering.
Temperature Control and Fertilizing
The optimal growing temperature for bougainvillea is between 20-30°C. Low or fluctuating temperatures can cause leaf drop. Especially in winter, if the plant is brought indoors too late, the leaves will fall. Use decomposed organic fertilizer and adhere to the principle of applying thin fertilizers frequently to avoid root burn and leaf drop.
Prune Dead Leaves
When bougainvillea leaves drop, the plant may experience varying degrees of yellowing. At this time, cut off the yellow leaves but keep the branches. After new growth appears, cut off the dead branches. If leaf drop occurs during the acclimatization period or winter, it is a normal phenomenon. Simply place the plant in a shaded area, promptly clean up the fallen leaves, and it will be fine after a while!
