Ginger

Sowing: Ginger is propagated from rhizome pieces rather than seed, cut into one- to three-inch sections each bearing several healthy buds. The cut surfaces are left to dry and callus for a day or two before planting, then set about an inch deep with a bud pointing upward, spaced roughly six to fifteen inches apart in loose, well-amended, well-drained soil. Sprouting is slow, sometimes taking fifty days or more, so growers often start rhizomes indoors before moving plants outside once night temperatures stay reliably above 50°F.

Care: The plant favors partial shade with only a couple of hours of direct sun, and needs soil kept moist but not wet; watering should stay sparing until new growth appears, to avoid rotting the rhizome, then increase along with regular feeding from slow-release fertilizer or compost supplemented by periodic liquid feed. As rhizomes swell near the soil surface, gardeners mound additional soil around the base one to three times through the season. Being frost tender, container plants must be brought indoors before temperatures drop below 50°F.

Ginger grown in cold or waterlogged soil is prone to root rot, the main problem reported for the crop, so sparing early watering and free-draining soil are used to guard against it. Placing plants in full sun rather than partial shade can scorch the foliage, causing brown-tipped leaves and poor growth. Beyond these conditions, ginger is generally reported to have few significant insect or disease problems.

Harvest: Young or "baby" ginger, valued for its milder, less fibrous flesh, is dug five to eight months after planting, while fully mature rhizomes are left in the ground for nine to twelve months or until the foliage yellows and dies back. Rhizomes are gently dug out, leaving some in the soil if regrowth the following year is wanted, and can be lifted a few at a time so the remaining clump keeps growing.

Storage: Freshly dug rhizomes are dried in the shade before further handling, then kept unpeeled in the refrigerator for a few weeks, or frozen or dried for longer keeping.

Culinary: Fresh or frozen ginger rhizome is used in soups and stir-fries, and its young sprouts are also eaten. It is baked into gingerbread and gingersnaps, and sold commercially in powdered or candied form.

Medicinal: Ginger has long served as a herbal remedy for a wide range of conditions, with Indian and Chinese traditions recording its use as a tonic for thousands of years.

Ginger originates from the tropics of Asia, generally traced to southern China and Southeast Asia, and is considered one of the oldest known cultivated spices. Its name is thought to derive from the ancient Sanskrit word for "horn root," reflecting a long history of use and trade across Asia that carried it into tropical regions worldwide.
