What Is Wasabi?
Wasabi (Wasabia japonica) is a root-based vegetable native to Japan. The root is typically grated and historically served with raw fish dishes. Wasabi’s spiciness is delicious and its aroma is unique. It’s often sold as a powder, but its genuine flavor comes from the freshly peeled and grated root.
Pick The Right Plant
Before getting started, it’s important to select the right plant. Wasabi plants are cold- and damp-loving types of horseradish. While some other horseradish species can be grown in similar environments, they won’t give the same flavor as wasabi.
Furthermore, just like other types of vegetables, wasabi plants are available in numerous varieties. Look for plants with the scientific name “Wasabia japonica” to be sure of a wasabi flavor.
Create The Right Environment
Wasabi grows best in partial shade with temperatures between 62 and 68 degrees Fahrenheit during the day. However, it’s important not to let the temperature drop below 45 degrees Fahrenheit—the plant will become dormant and can die if exposed to freezing temperatures for too long.
As for humidity, wasabi loves moisture but cannot handle being in standing water. You’ll need to keep a steady but not excessive amount of moisture in the soil. The soil should stay damp but not soggy.
If your garden experiences long, dry summers, make sure to water regularly. You can also place a shelter over the plant to hold in moisture.
Plant The Wasabi
Wasabi prefers soils that are high in organic matter, with a pH of 6.5 to 7. Plant individual rhizomes a few inches in the ground and about 6-8 inches apart. In colder soils, you may need to wait until after the last frost to plant.
Regular fertilizing is essential for successful wasabi cultivation. You should apply a balanced fertilizer in early spring and then alongside four times a year—following the directions on the packaging.
Wasabi takes several months to mature and ready for harvest. Depending on the variety and the soil, it can take anywhere from nine months to two years for the rhizomes to reach the right size. The ideal size is two inches in diameter and a few inches in length.
Once you’ve harvested the rhizomes, you can grate them for the freshest wasabi flavor. Collect all of the leaves, too, so long as there are no signs of disease or damage. Wasabi greens can be eaten on their own or used in salads and other cooked dishes.
Growing wasabi at home requires patience and a little know-how. And it’ll be worth it in the end for its delicious flavor, pleasing aroma, and numerous uses in various dishes.
