To grow ginger root, plant a smooth root in a container, and place it in an indoor location with a temperature of at least 75 degrees Fahrenheit. Cut and replant the same root year after year.
- Purchase and prepare the ginger root
Purchase a ginger root that has smooth skin, a full appearance and several bumps. If the skin appears extremely wrinkled, the ginger is too old to sprout. Fill a bowl with warm water, and soak the ginger overnight. The next day, cut the wet ginger into sections that have at least two or three bumps on each piece.
- Plant the ginger
Select a pot that has drainage holes on the bottom, and fill it with commercial potting soil or an equal mixture of compost, loam, peat moss and sand. Bury each ginger piece 2 to 5 inches deep.
- Provide water and sunlight
Ginger is a tropical plant that needs humidity and sunlight. Water every other day by misting the plant with a spray bottle. Place the container in an area that receives partial sunlight. Move the container outside during the summer.
- Cut and replant
Once the plant has grown for a year, remove it from the container. Cut off the leaves and fibers, and cut away a portion of the root for your use. Replant the rest of the root for future growth.
