When going up the pot, you should plant it shallowly, bury the stem plate, and the false bulb should be exposed to the soil, which is beneficial to the root. After watering once, keep it in a semi-shaded place. In the future, spray or add plastic film cover, try to make the air humidity higher, less watering. When the temperature was maintained at about 20 ℃, the growth of lobule was seen. At this time, the new root has been issued and can be transferred to normal water and fertilizer management.

Young plants, the roots are rarely very delicate, such as rotten roots, soon all the roots will rot, the leaves are drooping. When these conditions occur, the plant should be removed from the pot in time, and the residue on the unrotten stem plate should be cleaned, washed, disinfected, and dried on the surface, and then inserted into the plain sandy soil according to the method of cutting.
