Ginger, a tropical plant, thrives in Asia, the Philippines and other hot, humid climates. It also makes an excellent houseplant when grown in adequate conditions. Growing tropical ginger plants, whether indoors or out, provides you with lush, vibrant green foliage, a fresh aroma and a variety of flowers depending on the species of ginger you are growing.
Prepare your garden soil with a mixture of peat moss, kitchen compost and loam soil. Alternatively, you can add these ingredients to a large-sized planter box. Loam soil is comprised of sand, silt and clay, giving it a higher amount of humus than other soils. The nutrients produced by the loam soil, in addition to the peat and compost, allow tropical ginger plants to thrive to their fullest potential.
Mix the soil and enriching ingredients thoroughly with a hand trowel or garden hoe. Evenly disperse the ingredients, chopping at solid chunks if needed.
Dig down into the center of the enriched soil, creating a sort of burrow, measuring approximately 8 inches deep.
Dump the live earthworms into the hole and cover them up with the soil. Pat down the top of the soil to level it.
Insert the tropical ginger root approximately 3 inches beneath the surface of the soil.
Water the area liberally once every four days, administering approximately two gallons of water at a time. Once the tropical ginger plant reaches a foot in height, increase the amount of water to three gallons every four days.
