1, control lighting

The most suitable growing environment of Liriodendron chinense in summer is semi-shady, and it should be kept in the shade during the summer growing season. 70% shading net should be used for outdoor planting to prevent the leaves from being exposed to the hot sun and avoid the leaves from burning and dimming. You don't need shading in winter, you can grow well if you are exposed to direct sunlight for more than 4 hours every day.

Step 2 water properly

The temperature is high in summer, so to ensure a certain amount of water, you can water it once a day to keep the soil moist, and water it in time when it is dry. When the weather is dry, it is also necessary to spray water on plants for humidification, or spray water on leaves, and pay attention to increasing the environmental humidity. Water twice a week in spring and autumn, and control water properly in winter. If the water supply and demand are unbalanced, the soil is too dry or too wet, or it is placed in the shade for a long time, it will easily lead to leaf loss.

3. Fertilize regularly

The growing season is from March to September, and some compound fertilizers or cake fertilizers are applied every 2-3 weeks. It is not suitable to apply too much fertilizer (especially nitrogen fertilizer) to mosaic varieties, 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.
