The planted sweet-scented osmanthus trees should be planted with original soil, and the depth of the planted sweet-scented osmanthus trees should be 10 to 15 centimeters higher than the original ground. finally, the tree pits are all filled with sturdiness, cofferdam and support, and watered for the first time.
