Light. Grows in sun or partial shade, but Florida's summer sun stresses it. About 25–40% shade in summer, especially after planting, prevents heat and leaf damage; too much shade cuts rhizome growth.
Water. In summer, established plants need rain or watering about every day. Curled leaves followed by burned tips mean it is too dry. Avoid waterlogged soil.
Soil and feeding. Use well-drained soil or a coarse mix such as Potting Soil; roots are shallow, so 8 in of mix is enough. Feed moderately to heavily while growing, but not in winter. Avoid salty soil.
Size. Grows to about 6 ft.
Problems to watch. Root and rhizome rots are the main problem; discard plants with rotten rhizomes. Insects seldom cause serious damage outdoors.
Good to know. Plant rhizomes in spring, around March in South Florida. For fresh use, harvest about four months after planting; older rhizomes turn very fibrous. It grows best at 70–85°F.
