1. -- Maintain Temperature --
Shanghai Phalaenopsis orchids prefer warmth and are not cold-resistant, with the most suitable growth environment temperature between 15-20 degrees Celsius. When temperatures drop below 10 degrees Celsius in winter, the growth of flowers stops, and below 5 degrees Celsius, frost damage can lead to death. In low winter temperatures, they should be moved indoors to ensure an environment temperature above 15 degrees Celsius and receive full-day sunlight care.
2. -- Scientific Watering --
The growth period of Shanghai Phalaenopsis orchid flower buds is in winter, when their water demand is high. When the soil surface is dry and white, it is necessary to water promptly. The water temperature should be similar to the room temperature, and water should be poured around the pot edge at the highest temperature in the afternoon to keep the soil moist without waterlogging.
3. -- Stop Fertilizing --
During the growth period of Shanghai Phalaenopsis orchid flower buds in winter, it is necessary to stop fertilizing but not watering, unlike other plant growth periods that require timely top dressing. Shanghai Phalaenopsis orchids should not be fertilized in winter. It can only be top-dressed in the spring of the following year. Fertilizing at this time not only fails to be absorbed by the plant but can also cause fertilizer damage, leading to root rot and withering.
4. -- Prune Flower Stems --
Before the growth of Shanghai Phalaenopsis orchid flower buds, it is necessary to cut off the flower stems that have bloomed with a sterilized pair of scissors, leaving 3-4 nodes. Pruning the flower stems can reduce nutrient consumption and allow nutrients to flow back to the main stem. It can also promote the growth of axillary buds and make the flowering period more lush.
