Tieshu’s habits are suitable for warm and humid, well-drained sandy soil with humus growth. Xi Yang shade, but in the germination period and must have sufficient light, or new leaves grow long and thin, appreciate the value is greatly inferior. In the winter but also pay attention to antifreeze. Tieshu cultivation and management is generally relatively simple, just three to five times a year nitrogen fertilizer, usually buried in the root topsoil crushed iron, potted can put some crushed iron mixed with the topsoil, or fertilizer in a small amount of sulfuric acid Ferrous (about 1%). More iron leaves of the tree, each year when the new branches grow, appropriate to go some of the lower the old leaves (or
