With the arrival of winter, many flower friends will find that the leaves of their cassia trees have a phenomenon of drying at the tip, which not only affects the appearance of the cassia trees but may also affect their growth. What are the reasons for the drying of the tip of cassia leaves in winter? How should we prevent and control it? This article will provide you with detailed answers.
Reasons for the drying of the tip of cassia leaves in winter1. Water deficiency
In winter, the temperature is low, and the air is dry. The rate of water evaporation from cassia trees slows down, but the moisture in the soil is easily lost. If watering is not timely, the cassia tree will have dry leaves due to water deficiency.
2. Soil compaction
Long-term failure to loosen the soil, improper fertilization, or uneven watering can all lead to soil compaction, affecting the cassia tree's absorption of water and nutrients, and thus causing the leaves to dry at the tip.
3. Diseases and pests
In winter, the temperature is low, and the occurrence of diseases and pests is relatively rare, but it still exists. Diseases such as cassia leaf blight and powdery mildew can cause the leaves to dry at the tip.
4. Insufficient sunlight
In winter, the day is short, and the intensity of sunlight is weakened. The photosynthesis of cassia trees is affected, leading to insufficient nutrient supply and dry leaves at the tip.
Prevention and control measures for the drying of the tip of cassia leaves in winter1. Reasonable watering
Watering in winter should follow the principle of "watering when dry and keeping the soil moist but not too wet." When the temperature is low, the frequency of watering can be appropriately reduced to prevent the soil from freezing.
2. Improve the soil
Regularly loosen the soil to increase soil aeration, which is beneficial for the cassia tree's roots to absorb water and nutrients. Reasonable fertilization can replenish soil nutrients.
3. Prevent diseases and pests
In winter, the temperature is low, and the occurrence of diseases and pests is relatively rare. However, prevention should still be strengthened. Regularly inspect the cassia trees, and take timely measures when diseases and pests are found, such as pruning diseased branches and spraying pesticides.
4. Appropriate shading
In winter, the intensity of sunlight is weakened, and appropriate shading can reduce the sunlight stress on the cassia trees, which is beneficial for their growth. Materials such as shading nets can be used for shading.
5. Pruning branches
In winter, pruning the cassia trees can reduce the number of branches, lower water evaporation, and also help with ventilation and lighting, improving the growth quality of the cassia trees.
There are many reasons for the drying of the tip of cassia leaves in winter, but as long as we master the prevention and control methods, we can effectively improve this phenomenon. It is hoped that this article can be helpful to many flower friends.
