Brassica juncea, commonly known as brown mustard, Chinese mustard, or oriental mustard, is an annual herbaceous plant of the Brassicaceae family. Native to the Himalayas and widely cultivated in temperate regions, it is grown for its pungent seeds used in condiments, as a leafy vegetable, and as an oilseed crop. The species germinates rapidly with minimal dormancy requirements.

Tips
Seeds germinate best at 15/25°C or 20-25°C temperature alternation. No dormancy or scarification required. Can tolerate temperatures as low as 10°C but germination is slower. Light is beneficial for germination. Sow directly outdoors or indoors 3-4 weeks before transplanting. Soil should be well-draining and fertile. Keep seedbed consistently moist until emergence. Thin seedlings to appropriate spacing based on variety use (baby greens vs mature plants).
