Dong Lixian Ye Liqin sent a text message. The woody and herbaceous plants in her plastic greenhouse were injured due to the low temperature. How can I remedy this? Answer: Director Hu Yimin of the Institute of Seedlings and Flowers of the Provincial Forestry Academy said that the flower grower must first cut away the frozen leaves, then pull a wire and place a warmer to warm up the greenhouse. At the same time, two extra layers of straw can be added outside the greenhouse to provide insulation. However, water must be sprayed less to control the temperature in the shed. If the roots are not frozen, the leaves will reappear after the spring.
