Wasabi is a plant in the brassica family, which also includes cabbage, broccoli, and horseradish.
The wasabi plant has large, green leaves and a thick, fleshy root. The wasabi root is where the wasabi flavor comes from.
The wasabi plant is native to Japan, where it has been cultivated for centuries. Wasabi was traditionally grown in shaded mountain streams.
Today, wasabi is still grown in these mountain streams, as well as in greenhouses.
So now that we know a little bit about wasabi, let’s answer the question: Is wasabi hard to grow?
Wasabi can be difficult to grow as it requires specific growing conditions and if you cannot meet these then the plant struggles to develop. Wasabi prefers a shady, moist environment with well-drained soil. It also prefers cooler temperatures that don’t fluctuate by much and it cannot tolerate frost.
How do you propagate wasabi?
Wasabi is typically propagated by rhizomes, or wasabi roots.
These wasabi roots can be difficult to find outside of Japan. However, wasabi seeds are available from some specialty seed retailers.
Once you have your wasabi root or seeds, you’ll need to create the perfect growing environment for your wasabi plant.
If you live in an area with the correct climate, you can grow wasabi outdoors.
If you’re interested in trying to grow wasabi, you can also propagate it from cuttings or seed.
To propagate wasabi from cuttings, take a 4-6 inch cutting from a healthy wasabi plant and remove the bottom leaves.
Dip the cutting in rooting hormone and plant it in moist potting mix.
Place the pot in a warm, shady place and keep the soil moist. In 4-6 weeks, the cutting should have rooted and you can then transplant it into a larger pot or into your garden.
To propagate wasabi from seed, sow wasabi seeds in well-draining soil in a shady spot in early spring.
Keep the soil moist but not wet and thin the seedlings so that they are about 6 inches apart.
