Reasons for Osmanthus Tree Leaves Turning Yellow
1. Temperature Reasons
The most suitable temperature for osmanthus trees to grow is between 15 to 25 degrees Celsius. If the temperature exceeds 30 degrees Celsius, its leaves are likely to turn yellow and dry.
2. Light Reasons
Although osmanthus trees are plants that prefer sunlight, exposure to direct sunlight is not recommended. Too much or too little sunlight will affect the normal absorption of the osmanthus tree, and insufficient absorption can lead to drying and yellowing.
3. Water and Fertilizer Reasons
When watering osmanthus trees, be sure to do so in moderation. Too much or too little water will cause the leaves to turn yellow. Fertilization also needs to be carefully measured; too much fertilizer can burn the osmanthus tree, while too little fertilizer means the tree won't get enough nutrition, which can also cause the leaves to turn yellow.
1. Temperature: If the temperature is not suitable, it's best to place it in a cooler and well-ventilated area, and first cut off the dry and yellow leaves. If it's winter, you should first provide it with some insulation.
2. Light: For example, in the summer, it's best to place it in a shady spot or do a good job of shading it. Otherwise, prolonged exposure to the sun will cause the leaves to turn yellow.
3. Water and Fertilizer: If it's caused by improper watering and fertilizing, then you should reduce the amount of fertilizer used. Generally, fertilizing once a month is enough at this time, and you can use diluted organic fertilizer, which is natural and easy to absorb. Watering should only be done when the potting soil is completely dry.
