Growing Turmeric & Ginger
Both turmeric and ginger would be considered tender perennials for zone 5. These are both tropical plants. They will grow well in containers though and you could move them outside during the summer months, after there is any chance of frost and then bring them into the house for the winter, again before there is any chance of frost. Indoors they will need a high light area with moderate feed and moisture. Outside they will need partial shade, especially from the hot afternoon sun.
