What Causes the Withering of Chrysanthemum Leaves
If you want to understand the reasons for the withering of chrysanthemum leaves, let's take a look together!
Chrysanthemum, also known as autumn chrysanthemum, longevity guest, yellow flower, golden flower, etc., is a type of flower that often blooms in autumn. Chrysanthemums have good adaptability, prefer cool environments, and are quite cold-resistant. When cultivated, they like fertile, well-draining acidic soil.
Chrysanthemums come in various shapes and sizes, with many types and uses, and are also great ornamental plants. However, during the maintenance of chrysanthemums, the leaves may turn yellow, which affects their ornamental value.
What Causes the Withering of Chrysanthemum Leaves
1. Insufficient Watering
Chrysanthemums prefer a moist environment. Insufficient watering can cause the leaves to turn yellow, but excessive watering that leads to waterlogging can also cause leaf yellowing.
Therefore, when watering chrysanthemums, it is essential to check the soil in the pot. Water only when the soil is completely dry, and water thoroughly. In the summer, when water evaporates easily, it is okay to water more frequently, but avoid watering at noon.
2. Over-fertilization
Chrysanthemums like fertilizer, but excessive fertilization may cause root burn, affecting the leaves. When fertilizing chrysanthemums, it is best to follow the principle of applying thin fertilizers frequently. For top-dressing, materials like sesame oil residue can be used, applying once every week or so. After the flower buds appear, apply less phosphorus and potassium.
3. Diseases and Pests
Chrysanthemums often suffer from a disease called leaf blight, which causes the leaves to turn yellow and wither. In such cases, it is necessary to cut off the affected leaves and then spray solutions like zinc omethoate or mancozeb, every two weeks until the disease is gone.
4. Unsuitable Soil
Chrysanthemums prefer fertile, well-draining, slightly acidic soil. If the soil is poor, it will affect leaf growth. In such cases, it is necessary to change the soil or use rainwater and rice washing water to irrigate the soil, making it suitable for chrysanthemum growth.
【Summary】
The drying of chrysanthemum leaves may be due to low soil moisture, preventing the plant from growing properly. It may also be due to excessive light intensity, causing the leaves to be scorched by strong sunlight.
Therefore, when maintaining chrysanthemums, it is necessary to repot them every spring to prevent soil compaction, which could affect the normal growth of the roots.
The above explanation of the causes of chrysanthemum leaf withering is shared in hopes of bringing a little help to your life!
