Planting culture soil
Liriodendron has strong adaptability to the environment. When potted at home, you can prepare some culture soil yourself, for example, you can use some humus soil, cinder, garden soil or sand, and mix them evenly to make culture soil.
Avoid watering too much
Liriodendron likes humidity, and water evaporates quickly in summer. Keep the soil moist and water it in time if it is not dry. When the surrounding environment is too dry, it is necessary to spray plants to humidify the environment or spray water on leaves. Water can be reduced appropriately in spring and autumn, and water should be poured every three or so. Plants need less water in winter, so water can be controlled properly. In order to avoid watering too much, the leaves will fall off.
Fertilization and supplementary nutrition
The branches and leaves of Liriodendron chinense grow rapidly, and spring, summer and autumn are the peak seasons of growth, so it is necessary to maintain sufficient nutrients to maintain growth. Liriodendron can apply more decomposed organic fertilizer, such as decomposed bean cake, chicken manure, sheep manure and so on.
For some varieties with striped leaves, we should pay attention to fertilization, not just nitrogen fertilizer, otherwise the leaves will turn green and lose their original stripes. In order to prevent the color of plaque from fading or disappearing, some phosphorus and potassium fertilizers should be applied frequently, for example, some dilute potassium dihydrogen phosphate solution can be poured on the leaves or sprayed.
Dressing and shaping
The long branches of Liriodendron chinense germinate quickly, so attention should be paid to pruning and shaping during its growth to promote the germination of lateral branches and maintain a good tree shape. Generally, only small plants are thinned and lightly cut, and modeling is the main method. Most of the old plants are huge, so when changing pots, you can cut them short once, cut off most branches, and at the same time, you must cut off some roots and plant them again, so that new leaves can sprout and the crown can be full and stylish.
Control lighting
Liriodendron likes to grow in a semi-shady environment. When the light is too strong in summer, it should be kept in a cool and ventilated place. Outdoor maintenance should be carried out in a cool place, protected from the sun, so as to avoid strong light burning the leaves and making them dull. When the light is weak in winter, plants can grow well without shading, and there are more than 4 hours of direct sunlight every day.
cutting
Cutting propagation can be carried out in spring and autumn, or the cut branches can be used as cuttings every time they are pruned. First, the robust branches with the length of 10 ~ 15 cm were cut as cuttings. Then remove the lower blades, leaving only 3-4 blades at the top and cutting the lower end into inclined planes. Then insert the cuttings into wet river sand or perlite, spray water to keep them moist and keep them in a poorly ventilated place. Generally, cutting 1.5 months can take root.
Now is a good season for planting and cutting Liriodendron. You can use this time to plant or cut down some beautiful Liriodendron for viewing.
