Gardeners living in USDA zones 8 through 12 are fortunate to have an ideal environment for growing ginger plants. Growing ginger plants is simple, and the rewards are bountiful. Ginger plants will thrive with little maintenance to produce delicious ginger root. What ginger plants lack in ornamental value they make up for with their fleshy rhizomes that flavor a variety of culinary dishes.
Prepare a partly sunny growing area for planting the ginger plants. Cultivate the soil down to a depth of 4 inches. Add 2 inches of compost to the top of the soil and work the compost into the soil with a garden spade.
Cut apart a ginger root so that each piece has at least two nodes (The nodes resemble the eyes of a potato.)
Plant each piece of ginger root in the soil with the nodes facing up. Space the ginger root pieces 6 inches apart, and cover them with an inch of soil. Firm the soil down gently with your hands to finish planting the ginger roots.
Water the ginger immediately after you finish planting the rhizomes. Water the soil just enough to saturate it. Keep the soil from drying out by watering the plants regularly as they grow. Do not provide so much water that puddles form.
Add 2 inches of shredded mulch around the ginger plants to keep the soil moist and help prevent weeds from encroaching on the plants.
