Southern Giant Curled Mustard Seed Highlights

  • Germination: 2 to 4 days
  • Soak: No need.
  • Harvest: 10 to 14 days for microgreens in the cotyledon stage, or wait a few more days until the first true leaves form. The microgreens will be a bit spicier at this stage. Try them at both stages to see which you like better.
  • Flavor: Spicy, bold mustard flavor.
  • Nutrients: High in Vitamins A, C, and K, calcium, copper, iron, magnesium, manganese, and potassium.

Southern Giant Curled Mustard seed is super easy to grow.

The microgreens have a red tinge along the edges of the cotyledons and true leaves. However, the red color doesn’t appear until the plants are larger.

These microgreens pack some spiciness but aren’t hot like the Wasabi Mustard microgreens.

Harvest these microgreens between days 7 and 18 for a zing on sandwiches or salads.

Control the spicy flavor by adjusting how many microgreens you add to your dish.

We use Southern Giant Curled Mustard seed in our Intensely Flavorful mix.

Seeding Density

Seeding Density for Southern Giant Curled Mustard Seed

By Weight

Home Microgreens Tray: 1.8 grams

1010 Tray: 4.5 grams

By Measuring Spoon

Home Microgreens Tray: 0.5 teaspoons

1010 Tray: 1.4 teaspoons

1020 Tray: 2.8 teaspoons

All volumetric measurements are level, not heaping spoons.

I use these vertical-sided measuring spoons because the seeds are easier to level with the straight sides.

These are my recommended seeding densities to produce a great-looking tray of Southern Giant Curled Mustard microgreens.

I like to allow microgreen leaves to develop to a larger size as they provide more nutrition & flavor than producing smaller leaves and stems.

Microgreen density depends on many environmental factors and seed germination percentages.

You may prefer to modify the seeding density, but my seeding densities are a great starting point if nothing else.

Check out the Home Microgreens Seed Density Course if you have a different size tray.


28.35 grams equals 1 ounce.

Three teaspoons equal 1 Tablespoon
