The cultivation of Liriodendron requires the use of loose, breathable and well-drained fertile slightly acidic sandy soil, which will grow poorly in cohesive soil or alkaline soil and be prone to diseases, which will weaken the plant growth and reduce the resistance for a long time.
I like semi-cloudy or scattered light, but I don't like cool and strong full sunshine in summer. In the growing period, it needs to be given certain lighting conditions. If it is maintained indoors, it needs to be placed in a bright place. If the temperature is suitable, it is best to strengthen ventilation to prevent the blades from falling off.
Liriodendron likes warm and humid growing environment, the suitable growing temperature is 20-25℃, the overwintering temperature should not be lower than 65438 00℃, and it can grow in a high temperature environment of 35℃, but it should be combined with shading and humidification. The humidity in the growing environment should be kept between 50% and 75%, and it can be slightly lower in the low temperature period in winter. In summer or spring, it is necessary to strengthen the humidity, and often spray water or water the plants and the growing environment for humidification, which is conducive to vigorous growth.
Liriodendron likes water and is drought-tolerant. Watering requires clean alternation. If you don't do it, water it thoroughly. In the golden season of late spring and early autumn, it is necessary to water frequently to avoid drought or waterlogging. Outdoor users should drain water in time after rain to prevent waterlogging. If the environment is dark and there are too many watering times, the leaves will fall more seriously, so it is necessary to control the watering times slightly.
Liriodendron needs sufficient nutrients in the growing season, so from April to September, granular fertilizer should be applied once a month or watered frequently to dilute fertilizer water, so as to ensure that the fertilizer supply in the basin soil is sufficient, and some elements can not be applied in a partial way, otherwise, it is easy to appear element deficiency and lead to poor growth potential of the whole plant.
The propagation of Liriodendron chinense is usually carried out by cutting, and 4-5 copies are the most suitable. Before the new shoots grow, cut off the mature upper annual branches, the length is about 10 cm, remove the lower leaves, and only keep the upper 2-3 leaves, then plant the cuttings in clean river sand and water them. If possible, it can be sealed with plastic film to keep warm and moisturized, and it can take root and replant in about a month. If it is not sealed with plastic film, it is best to spray water frequently to increase the humidity of the surrounding air, otherwise the cuttings will easily dehydrate and wither, leading to the failure of cuttings.
Because Liriodendron needs to keep warm in the growing season, it is easy to shed leaves in the low temperature period in winter, which leads to the "foot off" of the lower part, which seriously affects the ornamental value. So pruning is very important. Generally, it is cut again after leaving the house in spring to promote multi-branch and lay a good foundation for growing good plant types in summer. In summer and autumn, short branches and long branches are dominant, and plant type is dominant.
In addition, young Liriodendron trees need to be changed once a year, and large trees need to be changed once every 2-3 years. There are fewer pests and diseases, which can be prevented as long as they are properly maintained.
