How to Fertilize Ginger

Zingiber officinale, otherwise known as edible ginger, has both medicinal and culinary uses. Ginger is easily grown in the ground or in containers with humus-rich soil. Starter rhizomes are available at your local grocery store. Ginger is a heavy feeder with specific nutritional requirements. Proper fertilization before and during growth gives the best results for healthy plants that yield healthy rhizomes.
