What are the methods to prevent bud drop in Phalaenopsis orchids?

To prevent bud drop in Phalaenopsis orchids, pay attention to the following points: The indoor temperature must be suitable. From autumn and winter onward, from bud formation to flowering, the temperature generally needs to be above 5°C. If the temperature is too low, it can easily cause yellowing leaves or bud drop.

Reasonable pot soil dryness and moisture: When Phalaenopsis orchids are forming buds and growing flower buds, only keep the soil slightly moist. Avoid watering too much or too frequently; if the pot soil is too wet, buds will drop very easily. The ambient air humidity can be higher; when the temperature is high at noon, sprinkle some water on the ground.

Fertilization must be sufficient. Every time a Phalaenopsis orchid blooms, it needs a large amount of fertilizer; when new leaves grow after flowering, apply a nitrogen-based fertilizer once every 7 to 10 days. During autumn and winter when the flower stem grows and buds form, apply a phosphorus- and potassium-based fertilizer once every half month. Before and after flowering, apply a light fertilizer 1 to 2 times, otherwise the flower buds will easily drop gradually from bottom to top and from large to small.
