How to Grow Awapuhi

Zingiber zerumbet, also known as awapuhi kauhiwi or shampoo ginger, is a tropical, perennial, ginger plant that is winter hardy in U.S. Department of Agriculture plant hardiness zones 8 through 11. Awapuhi boasts green, pinecone-like, bracts that deepen to an attractive red color before opening creamy, yellow blossoms in mid to late summer. Also called pinecone ginger, awapuhi is a low-maintenance addition to tropical gardens and home landscapes.

Things You'll Need

  • Shovel
  • Peat moss
  • Leaf mold
  • Perlite
  • Garden hose
  • Water-soluble ginger fertilizer

Instructions

    • 1

      Grow awapuhi in a full sun location with fertile, moist and well-draining soil. Select a planting site that gets at least six hours of direct sunlight per day to ensure vigorous growth.

    • 2

      Work 3 inches peat moss, 2 inches loam, 2 inches leaf mold and 1 inch perlite into the soil to a depth of 6 inches. Plant awapuhi plants at the same depth they grew in their nursery containers; plant awapuhi rhizomes under 4 inches of soil.

    • 3

      Irrigate awapuhi regularly while it is actively growing. Provide up to 2 inches of supplemental irrigation each week. Maintain evenly-moistened soil, but allow the surface to dry slightly between each irrigation.

      Fertilize awapuhi two times per year with a water-soluble fertilizer that's specially-formulated for use with ginger plants. Apply the first application in the early spring, when the plant is coming out of its dormancy; apply the second application six to eight weeks after the first. Consult the application and rate instructions listed on the fertilizer packaging.
