Remember these points when bougainvillea blooms, and the flowering period will be long without the buds dropping
Bougainvillea easily drops its flower buds, and it may be due to these reasons: 1. Lack of light 2. Lack of fertilizer 3. Lack of water. Missing any one of them can easily cause flower drop
1. Lack of light: bougainvillea needs plenty of light during its flowering period. In spring, full sun is best, so that the flowers bloom vividly. With insufficient light, the flowers are small, the flower color is dull, and the buds drop
2. Lack of fertilizer: before bougainvillea blooms, it needs phosphorus and potassium fertilizer to supply its flowering. If phosphorus and potassium fertilizer is insufficient, flower drop, bud drop, and nutrient deficiency are likely to occur. Before bougainvillea blooms, we should apply phosphorus and potassium fertilizer two or three times, once every 10 days, combined with water control and full sun. In this way, it blooms profusely, with large, brightly colored flowers, and is very robust
3. Lack of water: bougainvillea needs plenty of water during its flowering period. If it lacks water, it easily drops flowers; if it lacks water too much, it easily drops all its buds. Therefore, during the flowering period, bougainvillea must be watered sufficiently. After flowering, promptly cut off the spent flowers and prune the branches, and at the same time apply a multi-element organic fertilizer or general-purpose fertilizer to let it replenish the nutrients consumed by flowering. If you want bougainvillea to bloom again, apply phosphorus and potassium fertilizer once about every 10 days, then control water,
wait until the leaves of the bougainvillea are a bit wilted, then water a little; the next day the leaves can stand up again, then control water again, and repeat this. After about a month of water control, you can see flower buds emerging. At this point, apply phosphorus and potassium fertilizer once more, and it can bloom again, blooming profusely, with flowers but no leaves in between, making it very ornamental
