Osmanthus is a popular flower to grow, as it has beautiful blooms. However, many people encounter the problem of osmanthus leaves falling off. Why do osmanthus leaves fall off so easily? Let's find out the reasons below.
1. Overwatering
Osmanthus needs proper watering during its growth. It is susceptible to waterlogging. If the amount of water is not carefully controlled or the watering frequency is too frequent, the roots may be damaged, affecting their absorption and transport functions. In this case, place the plant in a well-ventilated area to promote water evaporation and help the plant recover as quickly as possible.
2. Insufficient light
Osmanthus is a sun-loving plant. Insufficient sunlight will prevent it from photosynthesizing properly and cause it to drop leaves. It should be moved to a sunny location in time to get more sun.
3. Strong sunlight
Osmanthus trees need sunlight to grow, but too much sunlight can scorch the leaves, causing them to turn yellow and fall off. You can quickly move the osmanthus to a shady spot and allow it to recover on its own.
4. Nutrient excess
Osmanthus trees need nutrients to grow, but fertilizing without considering their needs can lead to nutrient excess, which accumulates at the roots and becomes difficult to absorb, causing root burn and leaf drop. Regularly apply diluted fertilizer. If too much fertilizer is accidentally applied, add water to promote fertilizer drainage.
5. Temperature effect
Osmanthus trees prefer a temperature of around 23℃. Excessively high temperatures in summer and freezing temperatures in winter can cause osmanthus leaves to fall off. Therefore, it is important to take measures to prevent heatstroke or cold damage depending on the season to avoid adverse growth conditions.
6. Pest and disease infection
In summer, the air is often hot and humid, making proper circulation difficult and potentially leading to the growth of pests and diseases, as well as causing leaves to fall off. Therefore, it's essential to ensure good ventilation. If pests or diseases infest the plant, prune the affected branches and treat with appropriate pesticides.
