Wasabi is widely considered to be one of the most difficult plants to grow. It takes two years to mature, requires a humid, temperate environment, and is highly susceptible to disease when grown in large quantities. The reward of growing wasabi outweighs the difficulty, since it has numerous health benefits and a distinctive fresh, sweet flavor, hot, that can’t be matched. If you’re up for a challenge, growing wasabi is possible when you replicate the wild conditions in which wasabi grows best.
