Hi Folks Some time ago people were asking about culturing wasabi. It does appear to be one of those plants that are not that ready to be domesticated in a mad rush. I write an e-zine about aquaculture, and I've recently published an interview with Michel Van Mellaerts who (with his wife) have developed a method of growing wasabi in a recirculating system. They spend a great deal of time and effort getting the technique sorted out - but now pretty much are forging ahead producing top grade wasabi. I'd say they are working on a scale way outside the average gardener, but it's interesting to see how they managed never-the-less. They're now exploring the nutraceutical potential of wasabi.
Other than writing the interview I've got no connection with New Zealand Wasabi Ltd, and I suggest if you want more information about growing wasabi for market etc to contact Michel, or at least have a look at their web site
