Detailed Explanation of Winter Management Methods and Care Key Points for Clivia
Heat Preservation
The suitable temperature for Clivia in winter is 15°C to 20°C, and it is best not to let it drop below 10°C. After the flower scape emerges, the temperature should be maintained at around 18°C, and the day-night temperature difference is best kept at around 10°C; otherwise, the flower scape will bloom before reaching the proper height, which easily leads to scape entrapment. Therefore, when the outdoor temperature at night drops below 10°C, it should be moved indoors. When the indoor temperature falls below 10°C, in addition to covering the surface of the potting soil with a 1 cm thick layer of charcoal powder for insulation, it should also be placed in a warm, sunny spot indoors. When the indoor temperature is particularly low, a plastic film can be placed over the flower pot to raise the temperature, but the temperature inside the cover must not exceed 25°C; if it does, ventilation is needed to lower the temperature.
Watering and Fertilizing
Clivia has fleshy roots and is afraid of waterlogging; excessive watering can suffocate the roots or even cause root rot. Especially in winter, because the temperature is relatively low and water evaporates slowly, the amount of watering should be controlled even more. The potting soil is best kept slightly dry, and watering about once every 20 days is sufficient. The water temperature should not be too low and should be roughly the same as room temperature. To increase air humidity, water can be sprayed on the ground around the pot. Avoid excessive watering that causes waterlogging or half-watering that affects root absorption. Fertilizer must be applied in the right amount, and it is strictly forbidden to apply concentrated fertilizer or raw fertilizer that has not been fermented and decomposed. Otherwise, it easily causes the leaf tips to scorch or rot.
