Growing Ginger and Turmeric in the South: Tropical Roots in Your Backyard

Ginger and Turmeric: Hidden Gems for Southern Gardeners

Most southern gardeners have never thought about growing their own ginger and turmeric, but both plants thrive in the exact conditions the South offers: heat, humidity, and long warm summers. Once you have tasted freshly harvested ginger root from your own garden, the dried powder from the grocery store will seem like a pale imitation. And homegrown turmeric produces roots with deeper color and more potent flavor than anything commercially available.

Both are also beautiful ornamental plants with large tropical leaves that can enhance any garden area while quietly producing underground treasure all summer long.

When to Plant Ginger and Turmeric in the South

Plant rhizomes in spring after soil warms to at least 65 degrees, usually late March through May in most of the South. In South Florida and the Gulf Coast, you can plant as early as February or March. Both plants prefer filtered shade or morning sun with afternoon shade in the hottest parts of the South, but can tolerate more sun in the Florida and Gulf Coast regions.

In zones 8b and warmer, ginger and turmeric are perennial, dying back to the ground in winter and returning reliably each spring. In zone 8a and cooler, you can grow them as annuals or dig and store the rhizomes over winter in a cool, dry location.

How to Plant Ginger and Turmeric

Purchase fresh, plump rhizomes from a grocery store, farmers market, or garden center. Choose organic rhizomes when possible since some conventionally grown ginger is treated with growth inhibitors. Break rhizomes into pieces 2 to 3 inches long, making sure each piece has at least one growing bud visible as a small, greenish bump.

Plant rhizomes about 2 inches deep in well-amended, well-draining soil with the buds facing up. Space them 8 to 12 inches apart. They will send up shoots within a few weeks. Keep moist but not waterlogged since both plants need moisture but dislike soggy conditions.

Growing and Maintaining Ginger and Turmeric

Both plants are low maintenance once established. Water consistently through the growing season. Mulch heavily to maintain moisture and keep soil temperatures even. A general balanced fertilizer applied every few weeks through summer supports healthy growth and large root development. Both plants grow 3 to 4 feet tall and make attractive additions to any garden border.

Ginger and turmeric are rarely troubled by pests or diseases in home gardens. The biggest threat is overwatering leading to rhizome rot. If leaves yellow and wilt despite adequate water, it may indicate rot. Improve drainage and reduce watering frequency.

Harvesting Ginger and Turmeric

Harvest in fall after the foliage yellows and dies back, usually October through December. Dig carefully with a fork around the outside of the planting, working toward the center. You will find a cluster of plump rhizomes at the center. Wash them, allow to dry briefly, and they are ready to use fresh or store in the refrigerator for several weeks.

For ginger, you can harvest young "baby ginger" starting in midsummer by carefully digging around the edge of the plant and breaking off some new growth without disturbing the main plant. Baby ginger is tender, mild, and does not need to be peeled.
