Mustard Germination Information

Mustard Seed Germination How to Sow Mustard:
  • It is a cool season crop that is best sown outdoors when the soil is cool in the spring or fall
  • Sow in early spring and make successive sowings, one 3-4 weeks later; sow again 6-8 weeks before first frost in the fall
  • In Zones 8 and warmer, sow in the fall for winter use
  • Seeds can also be sown indoors at 68-72°
  • Indoors and out, sow at a depth of 4 times the size of the seeds and expect germination in 3-10 days
  • It is about 40 days from sowing to harvesting
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Mustard:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Thin or space 6-8 inches apart in rows spaced 12-15 inches apart

Soil: Site plants in full sun in a rich, moist, well-drained soil. Fertilize prior to planting and again 3 weeks later. Mulch to keep the soil cool and moist

Additional Care: The thinned seedlings can be used as a flavoring. If planted too late in the spring or in warm weather, it will bolt, flower, and quickly go to seed
