Cash cows are native to Tanzania and can grow well in bright or dark places. In summer, we should maintain a high air humidity and pay attention to shade. In winter, we can maintain a relatively dry environment, but we need bright light. The cultivation medium is fertile and loose, rich in organic matter, good in aeration and strong in water and fertilizer conservation, but the slightly acidic soil without stagnant water is the best, and compound fertilizer is applied once a month during the growing period. Propagation can be carried out by sowing, lobular cutting and tissue culture.
