1, lighting control
Liriodendron likes to grow in a semi-shady environment, and the requirements for light are not very high. Therefore, after Liriodendron cultivation enters summer, it is necessary to do a good job of shading to provide shade for Liriodendron. When planting in the open air, the shading degree should be kept at about 70%. Don't expose the leaves to the sun to avoid sunburn and reduce the ornamental value of the leaves. There is no need to do shading in winter. If the sunshine is maintained for about 4 hours every day, Liriodendron can grow normally. The light should not be too strong or too weak, otherwise it will reduce the ornamental value of Liriodendron chinense.
2, reasonable watering
Liriodendron requires higher moisture, especially when the temperature is high in summer, because the evaporation of water is relatively large. So water it about once a day to keep the soil full of water. Don't wait until the soil is dry. When it is too dry, in addition to watering, it is necessary to spray water mist around the plants to improve the humidity. Water every 3-4 days in spring and autumn. In winter, it can reduce the amount of watering and promote safe overwintering. The moisture should not be too wet, otherwise it will affect the normal growth of plants and cause undesirable phenomena such as falling leaves.
3. Scientific fertilization
Fertilization is also very important in the growth process of Liriodendron chinense. Generally speaking, the growth period of Liriodendron is from March to September every year. After Liriodendron chinense enters the growth period, it is usually fertilized every half month or so. The fertilizers are mainly compound fertilizer or cake fertilizer and water. When topdressing, the amount of topdressing should be controlled according to the planting varieties, such as mosaic varieties, so you can't topdressing too much. Especially nitrogen fertilizer, otherwise it will easily lead to white growth and excessive green leaves, resulting in the loss of original characteristics of mosaic varieties.
4, plastic pruning
Liriodendron chinense is prone to white long branches, so attention should be paid to regular shaping and pruning during maintenance to maintain a good tree shape for Liriodendron chinense. Pruning in the young tree stage is mainly based on thinning and light pruning, and mainly on shaping Liriodendron chinense. When the plant type is too large, it is necessary to cut off most branches and remove some roots if necessary. Then transplant or change pots to promote plants to grow new leaves.
The above is a brief introduction of how to raise Liriodendron. So much for today's introduction. This article is for reference only, hoping to help everyone.
