You basically grow them in fully submerged soil/muck. A kiddie pool or water holding sizable container with 3-5" soil and 1-3" of standing water over the soil. One centrally placed plant in the spring with spread out and overtake the entire container through a summer. Plants will go dormant in the fall nearing winter. Dig out all sizable corms and eat them. Really only need to peel off the outer layer of skin and they are ready to eat raw or cooked. Leave a few to replant in new containers or the same container. They've survived mid teen temps here unprotected even when the surface water completely froze. Wouldn't say they survive that further north than zone 8ish if it were longer than a day or two. They will grow good in the same muck for 2-3 seasons before they won't have whatever necessary nutrients to thrive and therefore not spread as vigorously. So renew the soil every other season or two. Really not at all hard to grow.
