Chrysanthemum, as a traditional famous flower in our country, is deeply loved by people for its unique temperament and beautiful flowers. In the process of maintenance, many flower friends will encounter the problem of drying and yellowing of chrysanthemum leaves. This article will analyze the reasons for the drying and yellowing of chrysanthemum leaves in detail and provide corresponding prevention and control methods to help you raise healthy and beautiful chrysanthemums.
Reasons for the drying and yellowing of chrysanthemum leaves1. Improper water management
Chrysanthemum has a high demand for water, but excessive watering can lead to root hypoxia, causing the leaves to turn yellow at the tip. Uneven watering can also cause some leaves to turn yellow.
2. Insufficient sunlight
Chrysanthemum requires sufficient sunlight. If it is kept in a dark environment for a long time, the leaves tend to show yellowing at the tip.
3. Soil problems
Soil that is too wet, too dry, or compacted can affect the growth of chrysanthemum, leading to drying and yellowing of leaves.
4. Pest and disease attacks
Chrysanthemum is prone to attacks by pests such as aphids and red spiders. These pests extract nutrients from the chrysanthemum, causing the leaves to turn yellow at the tip.
5. Improper application of fertilizers
Excessive application of fertilizers, especially nitrogenous fertilizers, can cause excessive growth of chrysanthemum and yellowing of leaves at the tip. Improper fertilization may also lead to soil salinization and alkalinization, affecting the growth of chrysanthemum.
Prevention and control methods for drying and yellowing of chrysanthemum leaves1. Timely watering
Timely watering is the key according to the growth habits of chrysanthemum. Generally, watering 1-2 times a day to keep the soil moist is sufficient. When watering, avoid pouring water directly on the leaves to prevent diseases.
2. Appropriate increase in sunlight
Place the chrysanthemum in a place with sufficient sunlight, ensuring at least 4 hours of direct sunlight every day. If sunlight is insufficient, artificial lighting can be used as a solution.
3. Improving the soil
Choose loose, breathable, and well-drained soil, and regularly carry out soil loosening, aeration, and fertilization to improve the soil environment.
4. Preventing and controlling pests and diseases
Regularly inspect the chrysanthemum and deal with pests and diseases in a timely manner. Pesticides and fungicides can be used for prevention and control. It is also important to rotate medications to prevent pests and diseases from developing resistance.
5. Rational fertilization
Apply fertilizers according to the growth needs of chrysanthemum. During the period of vigorous growth, an appropriate increase in phosphorus and potassium fertilizers can promote the formation of flower buds and the opening of flowers.
Drying and yellowing of chrysanthemum leaves is a common problem in the maintenance of chrysanthemum. Understanding the causes and prevention methods can help us better care for chrysanthemum. It is hoped that this article can provide assistance to the majority of flower friends, allowing your chrysanthemum to grow robustly and bloom beautifully.
