Ginger plants grow from an edible rhizome, used as a cooking spice in both its fresh and its dried form. There are also ornamental ginger plants grown for their attractive foliage as well as for their interesting flowers. Grow ginger in most climate areas. If your winters are prone to freezing temperatures, grow ginger in a pot and bring it indoors for winter. Caring for your ginger plant properly ensures it remains healthy and productive for many years, whether you are growing it for its appearance or for its roots.
Plant ginger in a partially-shaded, garden bed that isn't prone to standing water or soggy conditions. Work 2 to 3 inches of compost into the top inches of soil to improve water drainage and soil nutrition prior to planting.
Place pot-grown ginger outside once frost danger is past in spring. Set it in an area protected from wind that receives partial shade throughout the day.
Water throughout the growing season, providing about 1 inch of water a week or enough to keep the soil evenly moist. Water pot-grown ginger every one to two days or when the soil begins to feel dry.
Apply a 1 to 2 inch layer of organic mulch, such as bark, around each plant to help preserve soil moisture. Mulching maintains soil moisture as well as preventing the growth of weeds around the ginger.
Fertilize potted ginger once a month throughout the growing season with a soluble plant food, following label instructions for exact application amounts. Lay a fresh 2-inch layer of compost over the soil in spring for garden-grown ginger to add nutrients to the soil.
Harvest ginger once it is established, usually beginning in the second year after planting. Dig up the roots on the outside of the plant and cut them off cleanly for use. Leave the roots near the center of the ginger clump in place, so the plant continues to grow.
