First, the feeding method

1. Soil: osmanthus trees are suitable for growing in loose and fertile soil. It can be made of humus soil, garden soil, sandy soil and cake fertilizer according to the ratio of 2332. This not only has certain nutrition, but also has good drainage. 2. Illumination: osmanthus trees like light. So put it in the sun and get plenty of light. But in summer, shade properly and avoid strong light. Seeing more light before flowering is beneficial to flower bud differentiation. 3. Water: osmanthus trees are very sensitive to water. Generally, after the soil surface is dry, it is necessary to replenish water in time. Water should be poured thoroughly, but there should be no accumulated water. 4. Fertilization: osmanthus trees need to be supplemented with fertilizer during the growth period. Generally, liquid fertilizer is applied once every half month, so that it can grow better. In addition, apply a little phosphorus and potassium fertilizer before and after flowering to supplement nutrients for it.

Second, matters needing attention

1. Proper pruning: The branches of osmanthus trees should be pruned regularly. Cut off all old branches, dead branches and weak branches, and remove the residual flowers after flowering. If the branches and leaves are too dense, which affects the internal ventilation and light transmission, it is also necessary to cut off the branches that are too prosperous, cross branches and overlap branches. 2. Winter in the north: Because osmanthus trees are not suitable for low-temperature growth, we must pay attention to keeping warm in winter in the north. Pay antifreeze before winter, and then wrap the trunk with newspaper. It is no problem to spend the winter outdoors.
