However, during the maintenance process, we sometimes find that the leaves of Osmanthus fragrans begin to dry up and fall off. So how to deal with it? Let’s learn more about it below.

1. Soil Problems

Generally speaking, if the soil is too acidic or alkaline, the leaves of Osmanthus fragrans will dry up. Therefore, you can choose slightly acidic soil for growth. For example, you can mix leaf mold, garden soil and sand in a ratio of 5:3:2 and the pH value should be maintained between 5.5 and 6.5.

2. Lighting issues

Osmanthus fragrans likes light but avoids direct sunlight, especially in the seedling stage. In summer or under strong sunlight, appropriate shade should be provided to prevent the leaves from being sunburned and drying out.

3. Temperature problem

If the temperature of Osmanthus fragrans is too high or too low for a long time, the tips of its leaves will dry up. The solution is relatively simple. If the temperature is too high, you can provide shade or spray some water to increase the air humidity. If the temperature is too low, just take some measures to keep warm.

4. Watering problem

Osmanthus fragrans is not tolerant to waterlogging. Excessive water can cause root hypoxia and rot. The soil should be kept slightly moist to avoid waterlogging. When watering, ensure that the soil has a certain degree of air permeability and water permeability, and avoid frequent watering.

5. Nutritional issues

If the roots lack potassium or oxygen, the leaf tips may dry up. Osmanthus fragrans is a plant that likes fertilizer. Therefore, during the germination and bud formation stages, it should be given more dilute nitrogen and phosphorus liquid fertilizers.

6. Pest and disease problems

Some diseases and pests can also cause its leaves to dry out, such as brown spot disease, red spider mites, etc. Therefore, the plants should be checked regularly, diseased leaves should be removed in time, and appropriate pesticides should be used for treatment.

In general, to deal with the problem of Osmanthus fragrans leaves drying and falling, you first need to find out the specific cause. For example, soil, light, watering, temperature, nutrition, pests and diseases, etc., and take corresponding measures to adjust and improve them.
