Cultivation & Care

Light, soil, water, climate, propagation, containers, feeding and winter protection.

7.Cultivation

FactorPractical guidance
LightPart sun to part shade; bright filtered light is generally suitable.
SoilAdaptable to loam, sand and clay; vigorous growth is favored by fertile, moisture-retentive but adequately drained soil.
WaterRegular moisture; avoid prolonged waterlogging. Established plants show moderate drought tolerance.
ClimateTropical to warm subtropical; humid conditions are generally favorable.
HardinessOften described for approximately USDA zones 9B-11.
Salt tolerancePoor; growth may be reduced in saline soil or irrigation water.

8.Propagation

Rhizome division

One of the most reliable methods. A mature clump can be divided so each section retains viable rhizome tissue and one or more shoots.

Stem cuttings

Healthy stem sections can sometimes be rooted under warm, humid conditions.

Offsets

Young shoots developing near an established plant can be separated once they have adequate roots.

9.Pests and Problems

The plant is generally regarded as relatively resistant to serious disease, but problems can occur.

  • Mites
  • Nematodes
  • Root problems associated with poor drainage or excess moisture
  • Leaf and growth stress from excessive sun, drought, or salinity
