Phalaenopsis is a very popular tropical plant and is favored by many people for its elegant flowers and unique appearance. However, many people who grow Phalaenopsis may encounter a problem, that is, the phenomenon of the flowers shriveling before blooming, which is also often referred to as "dry buds". The following will introduce in detail the reasons for the shriveling of Phalaenopsis flowers and the corresponding treatment methods.
Reasons for the shriveling of Phalaenopsis flowers
Excessive light: Phalaenopsis has rather special requirements for light. They prefer diffused light rather than direct sunlight. If they are exposed to strong light for a long time, the flower buds of Phalaenopsis may turn red and gradually shrivel, which is extremely unfavorable for the later blooming.
Improper watering: Both overwatering and underwatering can cause the flowers of Phalaenopsis to shrivel. Overwatering will lead to waterlogging in the pot and cause root rot; while underwatering, with the potting soil being too dry, cannot meet the water requirements for the growth of the plant, and will also result in the shriveling of flower buds.
Unsuitable temperature: The growth and blooming of Phalaenopsis have relatively high requirements for temperature. Either too high or too low a temperature will affect its normal growth and lead to abnormalities in flower buds. The ideal growth temperature is around 18 - 25 degrees Celsius. In winter, it is necessary to take measures to keep warm, and in summer, high temperatures should be avoided.
Poor ventilation: Phalaenopsis needs good ventilation conditions to maintain a healthy growth environment. If it is in a poorly ventilated environment for a long time, the growth state of Phalaenopsis will deteriorate, and the flower buds will also be prone to shriveling.
Insufficient humidity: Phalaenopsis prefers a humid environment. Insufficient humidity will cause the flower buds to shrivel. Especially in air-conditioned rooms or heated rooms, the air humidity is often low, which easily makes the flowers shrivel or even wither.
Treatment methods for the shriveling of Phalaenopsis flowers
Gradually move the Phalaenopsis to places with diffused light and avoid long-term exposure to direct sunlight. You can use sunshade nets to reduce the light intensity and remove the already shriveled flower buds.
When watering Phalaenopsis, alternate between wetting and drying, and just keep the sphagnum moss slightly moist. When overwatering occurs, strengthen ventilation to reduce waterlogging in the pot; when underwatering occurs, replenish water in time and spray to increase humidity. Pay attention to observing the dryness and wetness of the substrate and water at the appropriate time.
Keep Phalaenopsis in a location with a relatively suitable temperature, especially during the flowering period. The temperature difference should not be too large. Take measures to keep warm in winter and avoid direct exposure to high temperatures in summer.
Try to keep Phalaenopsis in a ventilated place, open windows frequently for ventilation in daily life to strengthen air circulation and provide a suitable flowering environment for Phalaenopsis.
In an environment with low air humidity, you can use a humidifier or spray to increase the humidity. When spraying, avoid spraying directly onto the flowers to prevent them from withering after getting wet.
The problem of the shriveling of Phalaenopsis flowers needs to be considered comprehensively from aspects such as light, watering, temperature, ventilation and humidity. Only by providing a suitable growth environment for Phalaenopsis can the phenomenon of flower shriveling be avoided and allow Phalaenopsis to bloom the most beautiful flowers.
