I'm very much a window-sill gardener, and I like to grow plants and
vegetables that are generally available, such as can be bought in
virtually any supermarket. I'd like to try growing some root ginger,
bought for the princely sum of 33p, and which seems to have a "down"
[with roots] and an "up" [with buds], but I'm not even sure of that !
Any tips as to how I can get it to grow, please ?
