Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the shrub from the container, gently tease the roots and cut away any circled or tangled roots. If planting from a rhizome, do not plant too deep, as this can cause rot to occur.
Position in prepared hole and backfill with soil, gently firming down. Form a raised or doughnut shaped ring of soil around the outer edge of the plant's root zone. This helps keep water where it's needed. Always water in well after planting to settle the soil around the roots and keep the soil moist for several weeks while the new plant establishes.
Mulch around the base with organic mulch like bark chips, sugarcane or pea straw, keeping it away from the base of the ginger.
Water deeply, once or twice a week during establishment. Keep damp once growing.
Give a big clean up and prune down at the end of summer if required. Fleshy off cuts can be composted and any rhizome divisions replanted.
Gingers work well in tropical gardens. They work well as an undergrowth planting, where the taller trees/garden gives protection to the lower ginger. Mix different gingers together, planting taller varieties to the back and shorter ones to the front of the garden. They also work well with other accent plants like cordylines, alternanthera and coleus.
