The ginger root is actually a rhizome. This tuberous stem grows beneath the soil surface. Grow ginger plants by planting the rhizomes in containers. Ginger takes approximately eight to 10 months to mature. If you live in a cooler climate, start your ginger indoors and set the container outside during the warm months. Bring it back indoors if the temperatures drop below 75 degrees F before the ginger is ready to harvest.
Purchase three ginger roots from your local supermarket. Select ginger roots that appear plump and have several buds along the rhizome.
Rinse the ginger root with cool water. Fill a large bowl with water and place the ginger roots in the bowl. Allow the ginger to soak overnight.
Select a container approximately 16 inches in diameter and 12 inches deep. Your container should be either clay or ceramic and have a drainage hole.
Fill the container with well-composted, well-draining soil. Ginger needs to be kept moist while growing, but the roots along the rhizome will become waterlogged if the soil does not drain well.
Place the container in a warm but partly shaded area; a spot that receives early morning sun or late day sun is preferred. The ginger won’t grow if it is exposed to direct, midday sun.
Place the ginger in the container on top of the soil with the buds facing upward. Lay the ginger roots across the surface so they are evenly spaced.
Gently push the ginger into the soil surface so the roots are still exposed but if you were to lift one, the impression would be on the soil. Do not lift the ginger, however.
Water the ginger. Pour the water slowly and allow the soil to gradually soak up the water. Add a thin layer of soil over the ginger. This layer of soil should be just enough to cover the ginger roots.
Water the ginger plants several times a week, but with only enough water to keep the soil moist. Do not let the soil dry out. When you see buds or sprouts break through the thin layer of soil, mist them lightly if you live in a dry climate.
Fertilize the ginger with an organic fertilizer such as fish emulsion. Apply fertilizer once every eight weeks after planting through the warm, summer months.
Stop fertilizing the ginger when the leaves of the plant begin to die back. As the leaves die back, water the ginger less often, allowing the soil to slowly dry out.
Harvest the ginger rhizomes when all the foliage has died back. Dig out the rhizomes from the soil and clean.
