Due to the cold winter in the north, some potted flowers originating in the South must be moved into the indoor winter, and there is a temperature problem of overwintering. Overwintering temperature is too low, will make some flowers suffer from different degrees of cold damage or frost damage, light leaves fall, while the weight is dead. The overwintering temperature is too high, so that they continue to grow in the winter, can not get the dormant or low temperature vernalization effect, the next year's growth and development and flowering results are extremely unfavorable. The following describes the suitable winter temperatures for several southern flowers for reference by family flower lovers. The winter temperature in Milan is preferably 10-12 °C. Too low and easy to fall leaves, too high, the top buds are likely to sprout, grow delicate branches and leaves, the following year is easy to remove from the outside, affecting flowering. The overwintering temperature of Prynne was better at 12-15 °C. At the same time light must be sufficient, otherwise it is easy to fall leaves or dead leaves. The overwintering temperature for winter is 5 to 10°C. Pay attention to proper ventilation and control watering. If the room temperature exceeds 15°C, the flower buds that have formed in the fall will be budded and flowered in advance, but the fragrance of the flowers is very light and the quality is not good. Camellia winter temperature is 3 - 5 °C as well. Camellia flower buds have formed at the turn of summer and autumn. If you do not sleep at a low temperature for a period of time, your buds will be stunted. If the room temperature exceeds 15 °C, it is easy to germinate in advance and cause deciduous buds, which can not bloom. Jasmin winter temperature is preferably 8-12 °C. The temperature is too low and easy to fall. If you do not pay attention to watering at this time, it is easy to die, too wet and easy to rot. Osmanthus overwintering temperature is 0-5 °C as well. If the temperature is too high, some of the leaf buds will germinate prematurely, the fine branches will be drawn, nutrients will be consumed, and the growth of the second year will be weakened and affect flowering. Kumquat kumquat, bergamot, Xiangyuan and other Rutaceae flowers, winter temperatures to 5-10 °C as well. Low temperatures favor dormancy and reduce nutrient consumption. However, if the temperature is lower than 5°C and the water is too much, it will easily cause a lot of defoliation and affect the flowering fruit set in the second year. If the temperature is too high, it will continue to grow. The thin branches and leaves will not bloom in the second year or fall a lot. Scorpion winter temperature is 10-15 °C as well. At the same time pay attention to the control of moisture, keep the relative humidity of the air not less than 60%, otherwise easy to dead leaves. The wintering temperature of the bougainvillea flowers is preferably 15-20°C. Attention should be paid to sufficient illumination. Temperature below 10 °C is easy to fall and affect the next year's flowering. If the temperature is lower than 5°C, there is a danger of freezing. Fuso winter temperature is 10-15 °C as well. If conditions allow, room temperature can reach above 18°C ​​and light is sufficient, winter will bloom as usual. As long as the fertilizer supply is sufficient, it does not affect the growth and development of the second year.
