Re: Shell ginger
If it is shell ginger, Alpinia Zerumbet, you can hardly damage them; especially in your zone. You can dig them up any time. You need to give this ginger plenty of space. Don't plant it next to a fence. The rhizomes get huge and this plant can pull the fence post out of the ground. I repeat, give this ginger plenty of room to roam because it will.
