The foliage plants are prolific in the tropical and subtropical regions, and their growth potential is strong. If they maintain the optimum temperature for growth at 25-30°C, they can produce continuously throughout the year.
In regions where changes in the four seasons are noticeable, cold temperatures often cause freezing or wilting of plants due to sudden exposure to cold temperatures. If you can be in the room before the full exposure to outdoor climate in early autumn, in order to enhance their ability to resist cold, you can gradually adapt to the very low temperature environment. Therefore, from the beginning of autumn to late autumn, the plants should be exposed to the gradually decreasing temperature and gradually adapt the plants to the cold climate. At the same time, the amount of watering should be gradually reduced, and the plants must be forcibly put into dormancy in order to enhance cold resistance. When winter arrives, the foliage plants moved into the room, especially the rooms with heating equipment, must always spray misty water on the leaves to increase the air humidity. The temperature difference between day and night in the room should be as small as possible. The minimum indoor temperature at dawn can't be 5-8°C, and it should reach 8°C-20°C during the day. If the above requirements can be met, it can generally be used for winter.
In addition, in the same room, there will be a temperature difference between the upper and lower parts of the house space. Therefore, it is possible to place the cold-resistance weak on the height of the bookshelf. The foliage plants placed on the windowsill are most vulnerable to cold winds and thick curtains should be used. As the temperature drops, the growth begins to slow, and it almost stops growing in the cold season. The time for drying the pots and soils is also delayed. At this time, the number of watering pots should be reduced. The standard of watering in winter is to dry the potted soil surface for 2-3 days before it is poured. However, there are heating devices and rooms that can maintain a certain temperature. Watering should always be taken care of at any time. In addition, the light and temperature required for the growth of plants cannot be considered for splitting. When cultivating foliage plants, the intensity of light and the amount of light must be controlled. Under adequate lighting, the leaves are thick and strong; on the contrary, the leaves are thin and the internodes are longer, and so-called leggy phenomenon occurs. In winter, the sunlight is oblique, and the light intensity is half of summer. Some of the hi-yang foliage plants should be placed near the south window of Xiangyang. In plants and plants that have been rotating in the shade for too long, avoid sudden exposure to outdoor direct light, otherwise the leaves may burn.
