Causes and control of bud drop of Phalaenopsis
The reasons for the budding of Phalaenopsis:
1. Improper lighting: the light needed for potted Phalaenopsis is generally 1/3 of that of terrestrial orchids, 50% in spring and autumn and 20% to 30% in summer.
2, uneven water supply: Phalaenopsis water supply, generally using the immersion method, that is, with a bucket, filled with water, pot Phalaenopsis immersed in water for 2 to 3 minutes, can be put forward.
3. Insufficient humidity: Phalaenopsis likes high humidity, and the annual relative humidity should be kept at 70% to 80%. During the dry season and summer, the leaves should be sprayed 2 to 3 times a day. The mountain can use a large tray filled with water. Put the potted Phalaenopsis with wood or small stones and place it in the pot to maintain the humidity around the pot.
4. Fertilization is not frequent: Phalaenopsis grows faster, the amount of fertilizer needs to be a little more, and master the principle of applying thin fertilizer frequently. Fertilization begins in spring, thin liquid fertilizer dominated by nitrogen fertilizer is applied once a week, and fertilization is suspended in hot weather; in the period of flower bud differentiation and formation after autumn, thin liquid fertilizer dominated by phosphorus and potassium fertilizer should be applied every 12 to 14 days; stop fertilizer after budding, otherwise it will cause bud drop.
5. Diseases and insect pests: aphids are easy to attract on butterfly orchid buds, so attention should be paid to catching and killing aphids.

Phalaenopsis is a uniaxial orchid without a pseudobulb that can store water. Instead, it preserves water with strong fleshy roots and succulent leaves. Because the succulent leaves and succulent air roots of Phalaenopsis are very fragile, potted plants are easy to rot if Rain Water is drenched or watered too much. Therefore, proper watering is the key to ensure its normal growth. The correct watering method is: watering should try to avoid splashing wet leaves, especially in winter, the most likely to cause rotten leaves. Water should be watered once a day during the growing season in spring and summer.
