The invention relates to a planting method of submerged plants. According to the planting method, the submerged plants, planting soil, wrapping materials, ropes and clay are adopted. The planting method comprises the following steps of when the submerged plants are planted, wrapping stems and roots of the submerged plants by using the planting soil, wrapping the bottom of the planting soil by using the clay, and wrapping the outer sides of the planting soil and the clay by using the wrapping materials, wherein the bottoms of root systems of the submerged plants are not wrapped by the wrapping materials; and meanwhile, binding the outer sides of the wrapping materials by using the ropes, and carrying out dispersed planting on the wrapped and bound submerged plants. According to the planting method, as the wrapping materials are adopted, the loss of the planting soil after the plants are subjected to dispersed planting is overcome, so that the floating-up rate of the submerged plants is greatly reduced. As the clay is adopted for bottom sealing, the problem of loss of the planting soil after the plants are subjected to dispersed planting is solved, the defect that the root systems of the plants cannot pass through the wrapping materials is overcome, and therefore the survival rate of the submerged plants is greatly improved. The water-permeable wrapping materials are adopted, and the contact between the root systems of the plants and oxygen in water is enhanced, so that the roots of the plants cannot be rotten due to oxygen deficiency, and therefore the survival rate of the submerged plants is increased.
