Controlling Wasabi

Flower season comes once a year for Wasabi Japonica, but…. What if we control that process? 

Why people love wasabi

Wasabi has enormous health benefits. It’s good for your heart, and for your liver, it even helps regenerate your hair. Of course, taste and uniqueness come into play as the food service industry’s poster boy for Sushi and Sashimi. Back in the EDO period, Shoguns were scrapping over this beloved Japanese herb. Why? They discovered it prevented food poisoning after they ate raw fish. 

Can it grow outside of Japan? 

Yes that’s right, it can grow outside its homeland of Japan and many of our friends are successful farmers. The horticulture world has been distracted by the perception it could be tricky to grow. But some hydroponic growers are proving it is possible to be commercially successful. Knowledge and experience is the key to the success of this tricky crop that needs a unique controlled environment, whether you grow hydroponically, in soil pots/beds or naturally in streams. But once you upskill, you can grow for both pleasure (it’s a stunning plant in full bloom below, and the smell well that’s indescribable) and local food service. 

Is it economical to grow Wasabi? 

Wasabi may well be a high value crop (up to $250 per kg of rhizome) but long production cycles, circa 2–3 years, make this a niche specialist crop best designated for high-end restaurants. Most growers will supplement yields by selling Japanese accessories or young plants to cover periods between harvests. So you may want to put your marketing hat on and diversify into Japanese culture and food service. 

All that’s left to say is – do you want to start growing? We are here to help. 

Nice cool temps year round, neutral pH, and a high humidity will get you going.
