1, potted osmanthus fragrans is to prevent the soil from hardening and stiffness, and the pot soil must be changed every two years. In addition, in order to prevent the disease from getting worse, the roots of osmanthus fragrans trees should be pruned when changing the soil, so as to prevent the disease from getting worse.

2. Potted osmanthus trees like slightly acidic soil, which is loose and fertile, well drained, and the pH value is between 5.5 and 6.5, which is the most suitable for growth. If the soil acidity is too high, the leaves will turn yellow and grow slowly, while if the soil alkalinity is too strong, the leaves will dry up, wilt and even die. When changing pots every spring, it is recommended to use soil (or soil mixed with humus soil), and the garden soil and river sand should be mixed at a ratio of 5:3:2. You can spread some rotten chicken manure on the bottom of the basin as base fertilizer. In the growing period, decomposed alum can be used as fertilizer to avoid soil alkalization.
