Seedlings : Wasabi Mustard Growing Kit – Includes Seeding Tray

Wasabi mustard grows best in temperatures between 64–72°F (18–22°C). It's heat sensitive and will bolt in hot weather. 

Wasabi mustard prefers well-drained, slightly acidic to neutral soil with a pH of 6.0–6.5.If your soil pH is outside this range, you can add amendments to adjust it. 

Wasabi mustard needs regular watering and about 5 cm of water per week. Keep the soil moist but not wet. 

You can start harvesting single leaves about 25 days after planting, or harvest the whole pod after a month. The flavor of wasabi mustard intensifies as it matures, so the leaves will be more pungent when fully grown. 

In winter, protect wasabi mustard with a cloche or heavy row cover. 

Plant seeds inside or outside, about 2 cm apart, three weeks before the last frost date.After sprouting, thin to 10–15 cm apart. 

Mulch around the plants to help retain soil moisture. 

Prune back any leaves or stems that remain wilted for more than a few days. 

When the seed pods turn from green to brown, collect them before they break open and sow seeds all over the garden. You can use the seeds to make pickles, relishes, dressings, or your own specialty mustard.
