The reasons why the sweet-scented osmanthus tree does not bloom are unsuitable soil, insufficient light, improper water application, and imbalanced fertilizer ratio.

1. The soil is not suitable

It is more suitable to grow in sandy soil. If the soil is alkaline or hardened, the growth will be restricted, resulting in 3-5 No flowers will bloom within a year. When maintaining it as a potted plant, you can replace it with new pot soil to ensure the supply of nutrients for growth. If you maintain it outside, you can water it with water added with vinegar to alleviate the acidity and alkalinity.

2. Insufficient light

It prefers light when growing. If there is insufficient light for a long time, it will not be exposed to sunlight, and natural flower buds will not be formed, which may result in no flowering. During the growth period or before flower buds form, provide sufficient sunlight to ensure that the flowers bloom and the quality and quantity are guaranteed.

3. Improper application of water

Excessive application of water will cause the long-term growth environment to be very humid, or no water is applied for a long time, which will lead to poor plant growth and affect flowering. Water can be applied appropriately according to growth needs, and excessive waterlogging should not be caused.

4. Imbalanced fertilizer ratio

It likes fertilizer, so more fertilizer needs to be applied. However, if too much nitrogen fertilizer is applied, the branches and leaves will become elongated and flowers will not bloom. Subsequent fertilization requires a coordinated proportion, increasing the application of phosphorus and potassium fertilizers.
