To breed:

Spring onions are propagated in separate plants in potted plants. before germination in early spring, root blocks are poured out and divided into sections from 2 to 3 sections. a large basin with a diameter of 40 cm without drainage holes is filled with loose and fertile loam, and a little foot pad is used as base fertilizer. Several segments of rhizomes are evenly planted to keep the plant growth dense and moderate, plump and pleasing to the eye. The soil of the basin is filled to the depth of the basin by 2 to 3. The first planting keeps the potted soil moist and opens the place with strong scenery. As the temperature rises, the plants grow and gradually fill the basin with water. It is appropriate to put a sparse shade environment in the middle of summer to keep the plants green. Dormant in winter, cut off the withered stem and store in the cold room.
