How to prevent Hosta leaves from withering and yellowing?

In the process of Hosta cultivation, the leaves are often withered and yellow. Preventive measures mainly include the following aspects:

1. Shady and wet cultivation environment. Jade hairpin should be planted in a shady and humid environment without direct sunlight. Potted hairpins should be placed in more than 80% shade in summer. Otherwise, due to the strong light, the leaves will become thinner and the color of the leaves will change from green to yellowish white; if it is heavy, the leaves will turn yellow and the leaf edges will become scorched.

2. The cultivation substrate is well drained and rich in organic matter. The sandy loam with deep soil layer and good drainage should be selected when planting in the open field, and the loose and fertile soil should be selected when potted. Poor drainage of the middle finger matrix will cause stagnant water, resulting in root rot and yellowing of leaves.

3. Appropriate amount of watering and fertilization. During the growth period of Hosta should not be overwatered, just keep the soil moist. The temperature is high in summer, watering should be timely, and when the air is dry, it is necessary to spray water on the leaves to avoid dry coke at the tip and edge of the leaves. Spray wine and water after each fertilization to prevent liquid fertilizer from sticking to the branches and leaves.

The withered and yellow leaves often appear in the cultivation of Hosta. Preventive measures: ① cultivation environment. Jade hairpin should be planted in a shady and dry environment without direct sunlight. Potted plants should be placed in more than 80% shade in summer. Otherwise, due to the strong light, the leaves will become thinner and the color of the leaves will change from green to yellow-white; if they are heavy, the leaves will turn yellow and the leaf edges will become scorched. ② culture medium. When planting in open field, sandy loam with deep soil layer and good drainage should be selected, or mixed with culture soil, and loose and fertile culture soil should be selected for pot cultivation. Poor drainage of the planting substrate will cause stagnant water, resulting in root rot and yellowing leaves. Appropriate amount of ③ watering and fertilization. The Hosta should not be overwatered during the growth period to keep the soil moist. The temperature is high in summer, watering should be timely, and when the air is dry, it is necessary to spray water on the leaves to avoid the phenomenon of dry coke at the tip and edge of the leaves. Spray water once after each fertilization to prevent liquid fertilizer from sticking to the branches and leaves.
