1. Key points for post-blooming care: After a Phalaenopsis blooms, it can still continue to bloom. Once the flowers fade, promptly cut off the flower stalk growing from the base of the plant to prevent nutrient consumption. 2. The flowers are pale and not vivid because the plant has been kept in a dark indoor place for a long time, resulting in poor ventilation and insufficient light. The frequency of ventilation must be increased, and sufficient light must be provided. 3. Drooping and soft leaves are mainly caused by insufficient light; the duration and intensity of light need to be gradually increased, and the leaf surface should be kept clean. Usually, when cleaning the leaf surface, do not wash or wipe it with water

1. Key points for post-blooming care: After a Phalaenopsis blooms, it can still continue to bloom. Once the flowers fade, promptly cut off the flower stalk growing from the base of the plant to prevent nutrient consumption.

2. The flowers are pale and not vivid because the plant has been kept in a dark indoor place for a long time, resulting in poor ventilation and insufficient light. The frequency of ventilation must be increased, and sufficient light must be provided.

3. Drooping and soft leaves are mainly caused by insufficient light; the duration and intensity of light need to be gradually increased, and the leaf surface should be kept clean. Usually, when cleaning the leaf surface, do not wash or wipe it with water. Instead, use a cotton ball dipped in 75% alcohol or beer to remove dirt, so as to prevent bacterial infection. It may also be caused by excessively high temperature, in which case ventilation and cooling are required.

4. Leaf spots and perforation: Black spots sometimes appear on Phalaenopsis leaves, and in severe cases, rot and perforation occur, and even the leaf color turns white. This is mainly because the light is too strong, or because reflection or focusing from glass and other objects is refracted onto the leaf surface, causing leaf scorch or anthracnose. In this situation, light must be reduced, the light duration shortened, the diseased leaves cut off, and then carbendazim solution used to wipe and disinfect them.

5. Softening and rotting of leaves is mainly caused by bacterial infection due to poor ventilation, excessive moisture, and other factors. If the symptoms are mild, the soft-rotted leaves can be cut off immediately, and then all the healthy leaves should be disinfected with alcohol to prevent the spread of pathogens. If the plant is severely affected, disinfection and isolation treatment are required.

6. Root rot: If the symptoms are mild, the rotten parts of the root system can be cut off, and then careful disinfection is sufficient. If the root rot is severe, the plant needs to be taken out, the rotten roots cut off, then placed in a ventilated place to dry, and the flowerpot refilled with sterilized clean growing medium or sphagnum moss before replanting.
