Ginger is a tropical/subtropical rhizome crop that thrives in warm, humid Australian conditions. Queensland's Sunshine Coast (Buderim) has been producing commercial ginger since the 1940s. Home gardeners in warm zones can grow excellent ginger with minimal fuss. In cooler zones, container growing is the way forward. Always source organic rhizomes for planting. Non-organic supermarket ginger is often treated with growth inhibitor.

How to Grow Ginger in Tropical Australia

When to Plant

August to October. Plant at the start of the wet season build-up. Harvest March-June of the following year. Year-round growing is possible but autumn planting misses the critical warm growth period.

Soil
Rich, loose, well-drained soil high in organic matter. Ginger thrives in humus-rich loam that holds moisture but never becomes waterlogged. Raised beds or mounded rows work well. Add generous compost and aged manure before planting.
pH Range
5.5-6.5
Sunlight
Filtered light to part shade (3-6 hours direct sun). Full tropical sun can burn leaves and reduce yield. Ideal position is morning sun with afternoon shade, or dappled light under a tree canopy.
Spacing
25cm apart, 40cm between rows
Watering
Regular, consistent moisture throughout the growing season. Ginger needs a moist (not wet) environment. Water 2-3 times per week in warm weather. Misting foliage in dry conditions benefits growth. Red

Companion plants: Turmeric, Galangal, Banana, Pigeon Pea, Sweet Potato

Avoid planting near: Walnut trees (juglone toxicity)

Harvesting Ginger

When ready: Leaves begin yellowing and drying from tips down, typically 8-10 months after planting. Baby ginger can be harvested from 4-5 months (green stems, pale skin, very tender). Mature ginger has tough, brown skin and more intense flavour.

How to harvest: For baby ginger: carefully dig at edges of clump, snapping off young rhizomes. For full harvest: cut back dead stems, fork out entire clump. Brush off soil. Do not wash if storing.
