Why is the leaves of Osmanthus fragrans falling?

1. Lighting issues

This is a very light-loving plant. If there is not enough light, a series of problems may occur. Not only will the leaves fall, but during the flowering period, there may be very few flowers and the fragrance will be weak. Therefore, it is necessary to provide it with sufficient light. Generally speaking, it takes at least four or five hours a day. Also, don’t worry about direct sunlight, it won’t cause any harm.

2. Temperature problem

This aspect is mainly in winter. This plant is not very cold-tolerant and prefers warmer locations. In winter, if special attention is not paid to maintenance and the room temperature is below five degrees Celsius for a long time, it is very likely to cause leaf fall. In this case, it is necessary to move it indoors for maintenance and management. Specifically, the minimum temperature needs to be maintained between five and ten degrees. If conditions permit, it can be kept at around 20 degrees, but it should not be too high, otherwise nutrient consumption will increase.

3. Moisture problem

As we have said above, it is not tolerant to waterlogging. Therefore, if water accumulates, it will inevitably lead to a series of bad consequences. The first thing is root rot, and the second is leaf fall. If this phenomenon is observed, it needs to be remedied in advance. The most important thing is to control the amount of water. If there is no improvement, you need to take out the entire plant, rinse the roots, dry them, and then disinfect and replant them.

4. Normal phenomenon

This situation also mainly occurs in winter. Sometimes, when the temperature is very high in winter, its dormancy will be broken. Then, the leaves will naturally replace the old with the new, the old ones will fall off and the new ones will grow.
