I found a good big nice wasabi plant in a local nursery and could not resist.....
Now how to grow that? It is winter here and it could still go to -5C.
I probably have two oprions: first I grow it and hook it up to a sprinkler system or misting system (maybe the one I use for cuttings which goes on for 10 seconds per hour).
The other one would be we have a creek in the backyard but it does not flow much at all. Somewhere at this creek bank either in a big pot or in the ground.
Who grows wasabi?
