01Seed rhizome
Plant a plump, firm piece of rhizome with two or three growth buds, or “eyes”. Cut with a clean knife and let the cut sides dry for a day or two before planting, eyes up.
02Planting
Method
Plant pieces of rhizome with 2–3 eyes, buds up, 5cm deep. Sprouting takes 4–8 weeks, so be patient and keep the soil just moist.
Soil
Rich, loose, moist but free-draining soil with lots of compost. Raised beds and large pots suit it well.
Timing
Plant from September to November once soil is warm. In cool zones, start it in pots under cover.
Source
Buy untreated rhizomes from a nursery or organic grocer; shop ginger is often sprayed to stop sprouting.
Planting timing varies significantly by Australian climate zone. Set your zone above (or use the Find My Climate Zone tool) for guidance tailored to your own area.
03Growing care
- Keep soil evenly moist and mulch deeply to hold moisture and humidity.
- Give morning sun and afternoon shade; full sun scorches the leaves.
- Feed monthly with compost or a balanced organic fertiliser through summer.
- Hill soil over the rhizomes as they emerge, then reduce watering as the leaves yellow.
04Problems
- Frost — tender; leaves blacken and rhizomes can rot in cold, wet soil, so protect or grow in pots.
- Rhizome rot — rhizomes turn soft and smell sour in waterlogged soil; use well-drained beds and do not overwater.
- Root-knot nematodes — knobbly galls on roots and stunted plants, common in sandy soils; rotate and add plenty of compost.
- Slow sprouting — cool soil can delay growth for weeks; plant only when it is warm.
05Harvest & storage
Signs
Leaves yellow and die back, usually 8–10 months after planting. Baby ginger can be dug earlier, at about 4–6 months.
Method
Loosen the soil with a fork and lift the clump, keeping the rhizomes intact. Save a few plump pieces to replant.
Curing
Brush off soil and let skin dry for a day. Baby ginger needs no curing, but does not keep.
Storage
Mature rhizomes keep 3–4 weeks in the fridge, or freeze whole for 6 months or more. Dried and ground ginger keeps longer.
Preserving
See Dehydrating (drying ginger slices for tea and powder) for ways to keep a harvest surplus.

Rotation note
Avoid replanting in the same spot for 2–3 years; other gingers share the same rot and nematode problems.
