This article will deeply discuss the reasons why Hosta leaves become crispy and provide corresponding prevention and control measures to help flower friends solve this problem. Reasons why the leaves of Hosta become crispy 1. There is insufficient water. Hosta likes a humid environment. If watering is not timely, it will cause the leaves to become crispy and dry. Too much watering will also cause the roots to rot, which in turn affects the health of the leaves.
2. If you don't have enough light, you prefer a semi-cloudy environment. If you are exposed to direct light for a long time, it will cause the leaves to become brittle and yellowing. Insufficient light will also affect the growth rate of the hairpin.
3. Soil problems The soil is too hardened, poor drainage or insufficient nutrients will cause the leaves of the hairpin to become brittle, and pests and diseases in the soil will also affect the growth of the hairpin.
4. Pests and diseases attack Common pests and diseases include aphids, red spiders, powdery mildew, etc. These pests and diseases will absorb nutrients from the hairpin and cause the leaves to become brittle. Prevention and control measures for the crispness of Hosta leaves 1. Appropriate watering keeps the soil moist, but avoids stagnant water, and adjust the watering frequency in a timely manner according to seasons and climate changes.
2. Place the hairpin in a semi-cloudy environment with appropriate light to avoid direct light. During the period of vigorous growth, the light time can be appropriately increased.
3. Improve the soil by selecting soil with good air permeability and strong drainage, applying fertilizer regularly, and supplementing nutrients. You can choose organic soil such as legular soil and peat soil.
4. Regularly inspect Hosta to prevent and control pests and diseases. If pests and diseases are found, treat them promptly. Pesticides such as pesticides and fungicides can be used for prevention and control. At the same time, pay attention to rotating the use of drugs to avoid resistance to pests and diseases.
5. Trim sick branches and leaves and prune sick branches and leaves in time to keep the plants ventilated and transparent, and reduce the probability of occurrence of pests and diseases.
