Why Do the Flower Buds of蟹爪兰 Fall Off?
Answering the question of why the flower buds of蟹爪兰 fall off for netizens, the following is an introduction by the editor.
Why Do the Flower Buds of蟹爪兰 Fall Off?
1. Insufficient lighting:蟹爪兰 loves sunlight and needs to ensure that the plant receives at least 5 hours of sunlight daily. 2. Overwatering:蟹爪lan will drop flower buds in an overly humid environment, so water every 1-2 weeks. 3. Lack of nutrients: Apply phosphorus fertilizer to蟹爪lan to prevent it from dropping flowers. 4. Disease infection: Cut off the diseased leaves of蟹爪lan and spray with carbendazim.
1. -- Reasons --
There are generally four reasons why蟹爪lan drops flower buds: the first is insufficient lighting, which cannot ensure photosynthesis; the second is improper watering, either too much water or watering on the flower buds can cause them to fall off; the third is insufficient fertilizer, lacking phosphorus and potassium fertilizers; and the fourth is low temperature, as flower buds will wither and fall when the temperature is below five degrees Celsius.
2. -- Water and Fertilizer Control --
If flower buds fall off, first observe the condition of the potting soil. If the soil is moist, place it in a shady and well-ventilated area to speed up the evaporation of soil moisture. If the soil is relatively dry, water it slowly, not too much at a time. If it is still dry, you can use a spray. Apply a light fertilizer before the flower buds form to increase the content of phosphorus and potassium fertilizers, and no fertilizer is needed after the flower buds form.
3. -- Light and Temperature Management --
During the flowering period of蟹爪lan, the temperature is best maintained between 14 to 20 degrees Celsius. Too high or too low temperatures can cause flower buds to fall off. Also, ensure that蟹爪lan receives sufficient light. If it is being cared for indoors, place it on a sunny balcony and rotate the pot at regular intervals to ensure even light exposure. Artificial lighting can be supplemented for about three hours at night.
4. -- Ventilation --
When caring for蟹爪lan, it should be placed in a well-ventilated and breathable environment. A closed environment with poor air circulation can lead to poor plant growth, and lack of ventilation can cause diseases and pests to infect, which can also cause flower buds to fall off. Generally, open the windows for ventilation during the warm noon. If it has been infected by diseases and pests, remove the diseased branches and spray with the appropriate medication.
