when sowing mustard seeds in well-draining soil kept at 60–70°F with consistent moisture. Pre-soaking and bottom heat can reduce that to just 2–4 days . If nothing appears by day 14, check temperature, moisture, and seed viability. mustard seeds germination time
If no sprouts appear by day 14, germination has likely failed due to temperature, moisture, or seed age issues. : Consistent moisture is critical
