1. Temperature

Before blooming, keep the daytime temperature at around 20°C, not too high, and maintain 18°C at night. After about a month and a half, the flower buds of Phalaenopsis will gradually form. During the flower bud differentiation stage, adjustments must be made: 25°C to 28°C during the day and 18°C to 20°C at night. During the blooming period, make sure the temperature does not fall below 15°C, otherwise the blooming time will be shortened.

Temperatures are relatively low during the blooming period, so do not water too much. Generally, water once every 2 to 5 days. Do not spray water on the leaves; just keep the potting soil slightly moist.

3. Fertilizing

During the blooming period, reduce the amount of nitrogen fertilizer applied and apply some phosphorus and potassium fertilizer as appropriate to ensure more vigorous blooming and extend the blooming period. When temperatures drop in winter, stop fertilizing to avoid fertilizer damage.
