Mature ginger rhizomes (as sold in the grocery store) will generally be ready to be harvested in about 10-12 months, or after the leaves die back in the fall/winter. When harvesting, you can choose to harvest the entire plant or you can just cut off what you need and allow the plant to continue growing.
Most herbs can be harvested throughout the growing season, but turmeric root is best if harvested all at once when mature. Dig up the rhizomes and save a few pieces to plant for the following season. When planting in the spring in cooler climates, you can harvest before the first frost of the fall but will not yield much ginger.
