When planting, first ripen the soil, then put the saplings in the middle of the pond, and lift them while returning the soil. Don't nest the roots and let them spread. After watering, lift the roots of the seedlings to the level of the pond to avoid covering the joints. After the water completely permeates, cover them with a layer of loose soil to preserve water and improve the survival rate.

Fertile sandy loam is the most suitable for planting, and the indicators such as convenient irrigation and drainage, low water level and deep soil layer are comprehensively considered.
