Among many household flower enthusiasts, 旱金莲 is popular for its bright flowers and drought-resistant characteristics. Many flower friends have found that during the maintenance process, the leaves of 旱金莲 turn yellow, which not only affects the plant's appearance but may also endanger its growth. Why do the leaves of 旱金莲 turn yellow? This article will analyze for you.
Reasons for the yellowing of 旱金莲 leaves1. Improper water management
Water is one of the important conditions for plant growth. If watering is excessive or insufficient, it may lead to the yellowing of 旱金莲 leaves. Excessive watering can cause root hypoxia, which in turn affects the plant's respiration and nutrient absorption; insufficient watering will lead to soil dryness, causing the leaves to lack sufficient water and turn yellow.
2. Insufficient sunlight
旱金莲 thrives in environments with abundant sunlight. If kept in a dark place for a long time, it can lead to insufficient photosynthesis in the leaves, resulting in yellowing.
3. Soil problems
Soil quality directly affects plant growth. If the soil is compacted, has poor breathability, or lacks nutrients, the leaves of 旱金莲 are also prone to yellowing.
4. Improper application of fertilizers
Fertilizers are essential for plant growth, but excessive or insufficient application can lead to yellowing of the leaves. Excessive application of fertilizers can cause an accumulation of salts in the soil, preventing the plant from absorbing nutrients normally; while insufficient application can lead to slow plant growth and yellowing of the leaves.
5. Pest and disease infestation
Pests and diseases are also reasons for the yellowing of 旱金莲 leaves. Common pests and diseases include aphids, red spiders, and leaf spot diseases, which can damage the plant leaves, causing them to turn yellow.
Prevention and control methods for the yellowing of 旱金莲 leaves1. Reasonable watering
According to the growth habits of 旱金莲, keep the soil moist, and avoid splashing water on the leaves when watering to prevent leaf rot.
2. Provide sufficient sunlight
Place 旱金莲 in a sunny location to allow it to receive ample sunlight and promote photosynthesis.
3. Improve soil conditions
Regularly loosen the soil to increase breathability and add organic fertilizers to improve soil nutrients.
4. Apply fertilizers appropriately
Apply fertilizers according to the plant's growth stage and soil nutrient status, avoiding excessive application to prevent soil salt accumulation.
5. Prevent pests and diseases
Regularly inspect the plants and take timely measures when pests and diseases are found. Pesticides or biological control methods can be used for prevention and treatment.
There are many reasons for the yellowing of 旱金莲 leaves, and only by identifying the problem can effective prevention and control measures be taken. I hope this article can help you solve the problem of yellowing leaves in 旱金莲 and allow your plants to grow healthily.
