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.
I've been growing ginger at home for years, and ginger would have to be a serious contender for the title most neglected plant in my garden. (Which is a shame. Ginger is a beautiful and beautifully scented plant. I really should move it. One day...) I look at my ginger plants exactly once a year, at harvest time. I harvest them, replant them, and then forget about them for another year. I easily grow a year's supply of ginger root from them. I also have plenty left over to give away, both ginger root planting material and ginger for eating.
