Reasonable fertilization: Although Christmas claw lotus likes fertilizer, attention should be paid to the reasonable combination of nitrogen, phosphorus and potassium. Usually, more phosphorus and potassium fertilizers should be applied, especially when the flower buds have been formed and there are a lot of them, the amount of fertilizer should be continuously increased to prevent the flower buds from falling off due to unbalanced fertilization or lack of fertilizer.

Reasonable watering: After the buds of the crab claw lotus are formed, do not water them heavily. The amount of watering should be controlled at 80% of the usual amount, and then increase the amount of water after the buds open. Otherwise, too much water during the bud stage will not only cause the buds to fall off, but also cause root rot and even cause the stem nodes to fall off.

Reasonable light: Except for the summer when the Christmas claw lotus is afraid of the sun and needs to be placed under a shade shed for maintenance, it should be exposed to sunlight as much as possible in spring and autumn. In winter, it must maintain sufficient sunlight to ensure the accumulation of nutrients for the plant itself. If the above conditions are not met, it may also cause buds to fall.

Suitable temperature: The most suitable temperature for Christmas claw lotus is 15℃-25℃. If the temperature exceeds 28℃ in summer, the plant will be in a dormant or semi-dormant state. The room temperature in winter should be 15℃-18℃. If the temperature is lower than 15℃, the buds may fall off.
