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

Appearance and Use:

These 10-12 inch tall plants grow as basal rosettes of leaves and look much like spinach. They have a peppery tang and are cooked as winter greens. Brassica juncea var. crispifolia, Mustard, has cut, curled, crisp, and pungent-tasting leaves. Brassica rapa, Perviridis Group, Tendergreen or Spinach Mustard, has smooth, thick, glossy, dark green leaves that are less pungent. Harvest the outer leaves as they mature, but when they are still tender. They should be 3-4 inches long
