Rubber leaves are thick and wide, with rich green and high ornamental value. It is a very famous potted plant, which is very suitable for living rooms, courtyards and other empty places. But as a southern factory, there must be strict management measures. Otherwise, it will be very difficult for it to spend the winter. Tell you three skills, which will not only make it go through the winter smoothly, but also produce beautiful flowers. 1. Keeping warm in winter, rubber trees will be exposed to sunlight for a longer time, which will promote metabolism. Especially when the temperature is lower than 15 degrees, it is best to take heat preservation measures after the sun goes down and put plastic bags in the plants to prevent the damage of low temperature to rubber trees. 2. After fertilization in winter, rubber trees grow too slowly. At this time, as long as special liquid fertilizer is applied twice a month and a drop of ferrous sulfate is added when watering to improve the absorption of nutrient solution by plants, winter can be better and smoother. Pruning and cutting off some old, weak, sick and diseased branches and leaves can avoid excessive dispersion of nutrients, concentrate nutrients for healthy branches and leaves, and let them bloom more flowers in the coming year. If properly maintained, you can see a pot full of flowers next spring.
