1, Liriodendron chinense grows well in a bright and ventilated room. As long as there is about 4 hours of direct light indoors every day, it can grow well. Varieties with yellow and white stripes will lose their original characteristics if the light is too weak or the nitrogen fertilizer is biased. The optimum growth temperature is 15 ~ 25℃, and the lowest temperature in winter should not be lower than 5℃, otherwise the leaves will fall off. New leaves will grow next spring. ?
2. It grows well in the environment with high air humidity and sufficient soil moisture, but it has strong adaptability to the dry climate in the north. Pay attention to the pot soil can not be short of water, otherwise it will cause a large number of leaves to fall off. Water should be properly controlled under low temperature conditions in winter. Liquid fertilizer should be applied every 1 ~ 2 weeks in the growing season. ?
Change the basin once a year in spring. If plastic containers are used, pay attention to drainage. Potted soil is made of peat soil, humus soil and perlite with a small amount of base fertilizer, and can also be potted with fine sand. Liriodendron grows slowly and shoots easily, so it needs to be pruned frequently.
When the old plants are too big for indoor cultivation, they can be pruned again by changing pots, removing most branches, cutting off some roots and re-potted.
