Whether it will fall in winter can not be a general answer, it should be associated with temperature, because leaves and temperature. If the temperature is appropriate, keep above 5 degrees will not fall leaves, will still maintain the state of growth.
However, if the temperature is lower than 5 ℃ or even below zero, the leaves will fall and stop growing. In addition, it will also sleep in high temperature environment, and the leaves will fall in large areas, for example, when the temperature exceeds 30 ℃ in summer. Therefore, whether leaves fall depends on the temperature environment provided.
Even if it leaves leaves in winter, this period of time is very short, and it should be dealt with in time, otherwise it will easily lead to poor growth of plants. After falling leaves almost stop growing, at this time do not over water and fertilizer. Too much water will lead to poor respiration of roots, resulting in hypoxia and decay. If the soil is too dry, water it in a small amount. Pay attention to the water temperature, not too cold. Fertilization should be completely stopped, and so on to restore growth in the fertilizer
