1. Causes of yellowing leaves
Water issue: Excess or insufficient water can lead to yellowing of banyan bonsai leaves. Too much water can cause root hypoxia and root rot, while too little water will make the leaves turn yellow due to dehydration. Insufficient light: Banyan bonsai requires ample light for photosynthesis. If it is kept in a dark environment for a long time, the leaves cannot perform normal photosynthesis and will turn yellow. Nutrient deficiency: Lack of necessary nutrients, such as nitrogen, phosphorus, potassium, etc., can also cause yellowing of banyan bonsai leaves. Diseases and pests: Infestation by diseases and pests, such as leaf spot disease and red spider mites, can also cause leaves to turn yellow. Environmental changes: High or low temperatures, as well as sudden changes in the environment, can also cause yellowing of banyan bonsai leaves.
2. Fertilization suggestions
Nitrogen fertilizer: Nitrogen is one of the important elements for plant growth, which can promote leaf growth and make the leaves greener. However, excessive use of nitrogen fertilizer can lead to yellowing of the leaves, so it should be used in moderation. Phosphorus fertilizer: Phosphorus fertilizer helps in the development of plant roots and the formation of flowers and fruits, and proper application of phosphorus fertilizer can enhance the disease resistance of banyan bonsai. Potassium fertilizer: Potassium fertilizer can enhance plant resistance to lodging and diseases and pests. Moderate application of potassium fertilizer helps the healthy growth of banyan bonsai. Organic fertilizer: Organic fertilizers like compost and bonemeal can provide comprehensive nutrients, improve soil structure, and promote balanced growth of banyan bonsai.
3. Fertilization methods
Fertilization timing: Fertilization is best done during the peak growing periods of the banyan bonsai, such as spring and autumn. Fertilization amount: Fertilize according to the size and growth condition of the banyan bonsai, avoiding over-fertilization that can cause root burn. Fertilization method: Spread the fertilizer evenly on the surface of the potting soil and then water thoroughly to allow the fertilizer to penetrate into the soil.
4. Preventive measures
Reasonable watering: Water according to the water requirements of the banyan bonsai, avoiding too much or too little water. Light management: Ensure that the banyan bonsai has ample light but also avoid direct strong sunlight to prevent leaf burn.
