Liriodendron chinensis leaves have many causes of yellowing, and adjustments should be made according to the reasons. Barren soil, unsuitable light and moisture, and insufficient fertilizer are important reasons for yellowing Liriodendron leaves. If the yellowing of plant leaves occurs, soil needs to be replaced according to related reasons, and light, watering and appropriate amount should be given. Fertilize.
If the barren soil causes yellow leaves of the tulip tree, the soil needs to be replaced in time. Drain the barren soil, clean and disinfect the flower pots, install loose, ventilated, and well-drained organic fertilizer soil. After fertilizing the soil properly, move the plants to the flower pots and replant them. During transplanting, try to protect the roots of the plants.
If the leaves of the tulip tree are yellow due to lack of light or hot sun, the plants need to be placed on a sunny or warm and airy balcony or window sill. Shade work should be done in summer to ensure that its growth temperature is below 30 degrees, and choose to illuminate after sunrise or afternoon. Before winter comes, keep it indoors and move it outdoors in warm, sunny weather.
If too much water or lack of water causes yellow leaves of Liriodendron vines, you need to make adjustments and water appropriately. Water the pot soil after it has dried, and follow the edge of the pot. Do not over-water the water. Do not directly water the roots or water the leaves. Pay attention to the weather in a timely manner and move the plants to a more ventilated location before it rains to avoid exposing the plants to rain.
If the fertilizer is not enough, and the leaves of Liriodendron vines turn yellow, topdressing should be done in time. It is suitable for fertilizing at night. After fertilizing, the plant is placed on the window sill in a ventilated position, and watered the next morning to prevent the root of the plant from being burned. Plants need to be fertilized about once every 20 days during growth. Plants dormant in winter and stop fertilizing.
