Cassia, with its unique fragrance and graceful posture, is deeply loved by people. However, during the maintenance of cassia, the problem of yellowing leaves often plagues flower enthusiasts. This article will explore the reasons for the yellowing of cassia leaves and provide some correct fertilization methods.
### Reasons for Cassia Leaf Yellowing
1. ——Improper water management——: Cassia is not tolerant to waterlogging, and excessive water can lead to root hypoxia, which in turn causes leaf yellowing.
2. ——Insufficient light——: Cassia enjoys plenty of sunlight, and insufficient light can affect photosynthesis, leading to leaf yellowing.
3. ——Insufficient or excessive fertilizer——: Lack of fertilizer can lead to slow growth of cassia and leaf yellowing; while excessive fertilizer may burn the roots, also causing leaf yellowing.
4. ——Soil problems——: Soil that is too compact or has poor drainage can affect the breathing and water absorption of cassia roots, leading to leaf yellowing.
5. ——Pests and diseases——: Cassia affected by pests and diseases, such as leaf spot disease and aphids, can also cause leaf yellowing.
6. ——Environmental changes——: Cassia is sensitive to environmental changes, and sudden changes in temperature and humidity can lead to leaf yellowing.
7. ——Deficiency of nutrient elements——: Cassia's lack of certain nutrient elements, such as iron and magnesium, can also cause leaf yellowing.
### How to Fertilize Correctly
1. ——Choose the right fertilizer——: The fertilizer needed for cassia should be mainly organic, such as bone meal, fish meal, and compost, which can provide a variety of nutrients needed by cassia.
2. ——Fertilizing timing——: The timing of fertilizing cassia should be in spring and autumn, as these are the periods of vigorous growth for cassia, when fertilizing can better promote growth.
3. ——Fertilizing amount——: The amount of fertilizer should be determined based on the growth status of cassia and the fertility of the soil, avoiding excessive fertilization.
4. ——Fertilizing method——: When fertilizing, the fertilizer should be evenly spread on the soil around the roots of cassia, avoiding direct contact with the roots to prevent burning.
5. ——Foliar fertilizing——: In addition to root fertilizing, foliar fertilizing can also be carried out, diluting the fertilizer and spraying it on the leaves to quickly replenish nutrients.
6. ——Regular fertilizing——: Cassia needs regular fertilizing to ensure the nutrients needed for its growth, generally fertilizing once every two months is sufficient.
7. ——Pay attention to the proportion of fertilizer——: When fertilizing, attention should be paid to the proportion of elements such as nitrogen, phosphorus, and potassium in the fertilizer to meet the growth needs of cassia.
### Suggestions for Cassia's Daily Maintenance
1. ——Reasonable watering——: Keep the soil slightly moist, avoid waterlogging, and pay attention to drainage, especially in the rainy season.
2. ——Plenty of sunlight——: Ensure that cassia can receive plenty of sunlight to promote photosynthesis.
3. ——Regular pruning——: Prune cassia appropriately to remove weak and diseased branches and leaves, promoting new growth.
4. ——Prevent and treat pests and diseases——: Regularly check if cassia has signs of pests and diseases, and take timely measures for treatment if any.
5. ——Improve the soil——: Keep the soil loose and well-drained, and soil improvement can be carried out if necessary.
6. ——Adjust the environment——: Try to maintain a stable growing environment for cassia, avoiding sudden changes in temperature and humidity.
Through the above analysis and suggestions, flower enthusiasts should be able to better understand the reasons for the yellowing of cassia leaves and take correct fertilizing methods to keep cassia in a healthy growing state and emit a charming fragrance.
The above is a comprehensive introduction to the causes of cassia leaf yellowing and how to fertilize correctly, hoping to bring some plant-related knowledge to green plant enthusiasts.
