What causes Phalaenopsis orchids to drop their buds?
Phalaenopsis orchids are prized tropical flowers, yet all too often the buds drop before the flowers even open. The reasons are: (1) Insufficient temperature. From bud formation to flowering, the temperature should be kept above 15°C; if it is too low, the buds easily drop and the leaves turn yellow. (2) Soil that is too wet. Watering too much and waterlogged potting soil can also cause bud drop. (3) Insufficient nutrients. After Phalaenopsis orchids form buds, they need top-dressing, 1-2 times every half month, to keep replenishing nutrients; otherwise the buds will gradually drop from the bottom upward.
