Yeah, down here where those gingers grow wonderfully outdoors, they are water and fertilizer hogs and mine get some morning sun. I haven't grown culinary ginger for years just because so many others bloom and are prettier, but the clump I had at our other house grew to well over 7ft. one summer. Big fat rhizomes, too. They were under a gutter that overflowed on a regular basis all summer when it rained which is pretty often. They got timed-release pelleted fert at double the recommended rate and ate it all up.
