Why Do Phalaenopsis Orchids Drop Flower Buds
Phalaenopsis orchids dropping flower buds may be caused by improper fertilization, excessive watering, unsuitable environment, or insufficient lighting. Excessive application of nitrogenous fertilizer can lead to loose plant adhesion, insufficient lighting makes the stems weak, excessive watering can cause root rot, and an alkaline substrate or pH imbalance can result in the plant's flower buds dropping.
1. -- Improper Fertilization --
Unexplained dropping of flower buds in Phalaenopsis orchids may be due to improper fertilization. During the flowering period of the orchids, the additional fertilizer should be mainly phosphorus and potassium fertilizers. It is best to avoid using fertilizers high in nitrogen content, as this can cause the plant's flowers to be loosely attached and prone to falling off.
2. -- Excessive Watering --
Excessive watering can also lead to flower bud drop in the plant. When watering this type of plant, one should adhere to the principle of watering only when the soil is dry and slightly moist. Also, it is best to water less, as the growing medium for Phalaenopsis orchids is not ordinary soil but sphagnum moss, which has a very high water storage capacity and does not require frequent or excessive watering.
3. -- Insufficient Lighting --
Ensuring abundant flowers and rapid bud differentiation in the plant requires adequate sunlight. When the plant starts to differentiate flower buds, it must be ensured that it has sufficient scattered light exposure. Insufficient lighting may lead to weak stems and loosely connected issues.
4. -- Unsuitable Environment --
Phalaenopsis orchids thrive in neutral or slightly alkaline substrates. When fertilizing this type of plant, it is important to do so moderately and appropriately. Otherwise, the accumulation of inorganic salts on the sphagnum moss can cause severe alkalization of the substrate. If acidic substances are not used in time to improve the situation, the plant's stems and flowers may become prone to falling off.
