Management of osmanthus fragrans in northern winter?

Before winter, it is best to wrap the trunk with hemp rope. In addition to heat preservation, the biggest role is to prevent the strong wind from affecting germination in the next spring. Before the end of 10, be sure to pour enough frozen water. After watering, cover the trunk of 1 m2 with plastic film, and then cover it with a thin layer of soil or peat, which is beneficial for the seedlings to overwinter in the same year.
