Use tools such as wooden sticks, bamboo sticks, or metal brazing tools that have a diameter larger than the diameter of the cuttings, and prick holes vertically in the soil surface. L is about W cm deep, and the base of the cuttings is placed in the hole. The latent buds and the base of the leaf shaft are basically horizontal or slightly deeper than the soil surface, but should not be too deep, and the base should be compacted around.
