How to Grow Ginger

Growing guide

Overview

Ginger is a tropical perennial grown for its aromatic underground rhizomes, used fresh in Indian, Asian, and Caribbean cooking. Growers love it because it thrives in partial shade and does especially well in containers. It needs rich, well-drained loamy soil, consistent moderate moisture, and a long warm season to size up.

Soil & planting prep

Grow ginger in rich, loamy, well-drained soil with a pH around 5.5-6.5. Work in compost before planting, and space rhizome pieces 8-12 inches apart. Plant them 2-4 inches deep with the buds pointing up.

When to plant

Start ginger rhizomes indoors 8 weeks before your last frost date. Transplant outdoors only after the last frost has passed and the soil has warmed; ginger is frost-tender and is not a fall-planted crop. In warm zones, wait until spring soil temperatures are reliably warm before planting outside.

How to plant

1. Start with fresh, plump organic ginger rhizomes that have visible growth buds or eyes.
2. Soak the rhizomes in water overnight, then cut them into 1-2 inch pieces, each with at least one or two buds.
3. Let the cut surfaces callus over for about a day before planting.
4. Plant each piece 2-4 inches deep in rich, loamy, well-drained soil with the buds pointing up.
5. Space pieces 8-12 inches apart, water them in lightly, and keep the soil evenly moist but not soggy.

5 common mistakes to avoid

• Planting old or treated grocery-store ginger that never sprouts, because some rhizomes are treated with growth inhibitors or stored too long; buy plump organic or seed-ginger rhizomes with visible eyes.
• Setting ginger outside before the soil is warm, which causes rhizomes to rot or sit dormant instead of growing; wait until after the last frost and warm spring soil, or start indoors 8 weeks early.
• Keeping the soil constantly waterlogged, which is the classic cause of ginger rhizome rot; water moderately and grow it in well-drained loamy soil or potting mix.
• Giving ginger hot afternoon sun, which scorches the leaf edges and weakens the plant; place it in partial shade or dappled light rather than full sun.
• Harvesting too early while the leaves are still green, which produces thin, watery rhizomes; wait until the foliage dies back and the plant has grown for 240-300 days.

Harvesting & storage

Harvest the main crop when the leaves turn yellow and die back in fall, typically 240-300 days after planting. Loosen the soil and lift the whole clump, then cut off the rhizomes you need. Store unpeeled fresh ginger in the refrigerator for a few weeks, or freeze the extra rhizomes.

Companion planting

Good companions include turmeric and galangal, which want the same warm, moist, partial-shade conditions. Avoid planting ginger where large, aggressive root crops will compete for underground space; no common culinary companions are strongly antagonistic.

Growing in containers

Ginger grows well in a wide 5-gallon container with drainage holes. Use rich, loamy potting mix, keep the pot in partial shade, and water consistently, since container soil dries out faster than garden beds.

Pro tips

Start indoors 8 weeks before last frost. Soak a fresh ginger rhizome overnight, then plant 2-4 inches deep in rich potting mix. Prefers partial shade (unlike most edibles). Water consistently but do not waterlog. Harvest when foliage dies back in fall.
