I like warm, humid and semi-sunny environment. Should be born in acidic soil with deep and fertile soil, slightly barren. The optimum growth temperature of Liriodendron chinense is 16 ~ 27℃. 2 1 ~ 27℃ from March to September, and 16 ~ 2 1℃ from September to March of the following year. It can still grow normally at a high temperature above 30℃. The temperature in winter is not lower than 5℃.

If the temperature is lower than 0℃, the plants will freeze the fallen leaves, but if the stems are intact, new leaves will grow in the next spring. Liriodendron prefers wet to dry. When the air humidity is high and the soil moisture is sufficient, the stems and leaves grow luxuriantly. But too much water will cause waterlogging and root rot. If the basin soil is short of water or dry and wet for a long time, defoliation will occur. Liriodendron chinense has certain adaptability to temporary drought and air drying.

Liriodendron has a wide range of adaptability to light, and can grow in full sunshine, half sunshine or half shade. But the intensity of light has a certain relationship with the color of leaves. When the light intensity is high, the color of the leaves becomes lighter, and when it is semi-cloudy, the color of the leaves becomes dark green. In bright light, the color of spotted leaf species is more vivid. Rich, loose and well-drained sandy loam is suitable for this kind of soil. Potted soil is a mixture of peat soil, humus soil and coarse sand.

Cultivation techniques of Liriodendron chinense;

1, the suitable growth environment is semi-shady, and it should be maintained in the shade in summer. For outdoor planting, 70% sunshade net should be used to prevent the sun from being exposed to the sun. No sunshade is needed in winter, and direct sunlight should be used for more than 4 hours every day.

2, to ensure a certain amount of water in summer, you can water once a day to keep the soil moist. When drying, you should also spray water on plants to humidify them. You can also spray water on leaves, and pay attention to increasing the humidity of the environment. Water twice a week in spring and autumn, and control water properly in winter.

3. The growing season is from March to September, and some compound fertilizer or cake fertilizer water is applied every 2 to 3 weeks. Mosaic varieties should not be fertilized too much, otherwise the leaves will turn green and lose their original variety characteristics. Less nitrogen fertilizer should be applied to variegated varieties to prevent the color of patches from fading or disappearing.

4. Pay attention to shaping and pruning to keep a good tree shape. Young plants are thinned and lightly cut, and old plants can be cut off by changing pots and cutting off most branches. At the same time, some roots must be cut off and potted again to sprout new leaves.
