These rhizomes have been tenderly raised and harvested by us in the strictest organic method, in our very own hand-crafted soil. Soil that is supplemented with beneficial bacteria from compost tea, bat guano, worm castings, and naturally occurring minerals; we even add volcanic ash from an active volcano. Your rhizomes are top-of-the-line premium.
Zones 8a to 7b, mulch heavily (at least 6-8 inches thick) in the winter and you shouldn’t have to dig up and overwinter indoors. If doing this in these zones, it helps to cover the site with mulch after the soil is dry, then a layer of plastic for waterproofing, then another layer of mulch – it doesn’t like cold and wet – cold and dry wins. When planting outdoors in these zones, and you intend to overwinter in place, be sure to plant at the top of a slope or mound.
Common name: Ginger
Botanical name: Zingiber spp
Type: Herbaceous perennial in tropical zones
Scarification/Stratification: Ideally, soak rhizome in room temperature kelp water for 12 hours before sowing, it helps speed things up.
Hardiness: The foliage is not frost tolerant but as long as a heavy mulch is laid, root may overwinter in temperate gardens of zone 7b or higher, but it is safer to overwinter indoors in a dark, cool place then replant in the spring.
Sun requirements: Moderate light for germination (temperature is more important than light). In front of an indoor window is sufficient. If direct-sown, in a place with morning sun. After germination, the leaves will wilt in the hottest hours if in full sun, but springs back beautifully after shade hits it.
Water requirements: For germination, slightly damp soil. The rhizome has plenty of its own water. Once established, still moderate water.
Sow temp/season: If in zone 7b or higher, direct-sow in the container or garden bed it will grow in, in soils of 72-85F. This makes a bigger root system than transplanting. Some growers direct-sow plugs and lay down clear plastic to raise soil temperature.
Sow depth/spacing: Sow plugs two inches deep at 18 inch spacing, with the eyes pointing upward.
Germination time: 2-4 weeks depending on temperature and conditions. Sometimes longer, do not give up!! Temperature is key here.
Final spacing: 18 inches to 2 feet
Final height/spread: We’ve had a plant reach five feet tall and two feet wide in one growing season.
