Winter Ornamental Plant Temperature Regulation
Most of the foliage plants are poor in cold resistance and high temperature resistance. After the arrival of winter, the temperature difference between day and night in the room should be as small as possible. The minimum indoor temperature at dawn should not be less than 5°C to 8°C and should reach about 20°C during the day. In addition, temperature differences occur in the same room, so plants with weak cold resistance can be placed high. The foliage plants placed on the windowsill are vulnerable to cold winds and should be blocked by thick curtains. For a small number of species that are extremely cold-tolerant, they can be kept warm for the winter by means of partial separation or small spaces and re-filming.
