Wasabi is a notoriously challenging plant that demands consistently moist, cool conditions, high humidity, and dappled shade to thrive. Grow it in rich, slightly acidic soil with excellent drainage and keep temperatures between 45–70°F for best results. The prized rhizome can take 18–24 months to mature, so patience and careful attention to watering are essential.
