Ludisia discolor division propagtion can be done in spring and autumn, and usually every three years. Any plant with a high density of pseudobulbs can be separated, and at least 5 pseudobulbs that are joined together should be kept in each cluster. Before planting to reduce irrigation, so that the basin soil then. After plant separation, cover the bottom hole of the basin with broken tiles, then spread rough stones, occupying 1/5 to 1/4 of the depth of the basin, then put coarse-grained soil and a small amount of fine soil, and then plant with sandy loam rich in humus. The depth of planting was to put the fake bulb into the soil just now. The edge of the basin was left at 2cm along with the mouth and covered with green cloud grass or fine stones. Finally, water was poured into the shade for 10-15 days to keep the soil moist.
The seed of Ludisia discolor is very fine. There is only one embryo with incomplete development inside the seed, germinating force is very low, together with seed skin it is not easy to absorb water. Sow with the conventional method cannot germinate, and we need to use orchid fungus or artificial medium to supply nutrient, ability germinates. Planting fruit had better choose not cracking, surface with 75% alcohol after sterilization, remove the seeds, soaking with 10% sodium hypochlorite for 5-10 minutes, take out three times with sterile water rinse again can play in the cultivation of the bottle containing medium, and dark in the pure, the temperature about 25 c, stirring and then moved to the light that can form the original bulb. From sowing to transplanting, it takes half a year to a year. Tissue culture has been successful and can be propagated in this way if conditions permit.
