What causes osmanthus to drop leaves?

The osmanthus tree is a plant planted in many people's homes. It has a beautiful shape and a strong fragrance when it blooms. If the sweet osmanthus planted by me is losing its leaves, what is the reason? Let’s learn more about it below.

1. Soil compaction

The reason why osmanthus leaves fall off may be that the soil has solidified into lumps, making it impossible for the plant roots to absorb fertilizer . At this time, you can loosen the soil to make it loose, or you can directly change the soil and add base fertilizer to the soil. The pot can be changed every 1-2 years with loose, breathable and well-drained soil.

2. Too much water

Osmanthus needs reasonable watering during its growth process. It is afraid of waterlogging. If you do not pay attention to the control of water volume in daily life, or the frequency of watering is too frequent, it may cause damage to the roots, affecting the absorption and transportation functions and causing leaves to fall. At this time, you can loosen the soil and place it in a well-ventilated place to promote water evaporation so that the plant can recover as soon as possible. Osmanthus needs to be watered reasonably. The soil in the pot should be kept slightly moist during each watering, and the principle of not watering unless the soil is dry and watering thoroughly when watering is adhered to.

3. Too much fertilizer

Osmanthus needs nutrients to grow, but applying fertilizer without considering its growth needs may result in a large excess of nutrients, which will accumulate at the roots and be difficult to absorb, causing root burn and causing the osmanthus to lose leaves. Normally, light fertilizer should be applied. During the growing season, decomposed liquid fertilizer can be applied once every half a month, and 0.02% potassium dihydrogen phosphate foliar fertilizer can be added. If you accidentally apply too much fertilizer, you can water more to promote fertilizer excretion.

4. Lighting issues

If osmanthus is exposed to excessive light or darkness for a long time, it will cause leaves to fall off. Therefore, it must receive sufficient sunlight, such as 6-8 hours of sunlight in spring and autumn.

5. Pest and disease control

The strong fragrance of osmanthus flowers can easily attract pests and diseases, which can cause the leaves to fall off. Therefore, during the maintenance process, the osmanthus flowers need to be ventilated and air circulation maintained. When pests and diseases are found on the branches and leaves of osmanthus flowers, they must be removed immediately.

That’s it
