Red Garnet Mustard Highlights

  • Germination: 2 to 3 days
  • Soak: No need.
  • Harvest: 10 to 12 days; up to 20 days for true leaves.
  • Flavor: Distinct mustard flavor. These microgreens are quite spicy but not overly so.
  • Nutrients: Vitamins A, C, E, K, and antioxidants.

These mustard microgreens can be harvested at an early cotyledon stage or grown as long as possible in a microgreen tray into the true leaf stage.

The leaves are a solid red color with green stems. The color is intense, especially under grow lights. We think these are some of the prettiest microgreens.

The true leaves are very crenulated and green with red veins that will turn red as they mature.

It takes about 10 days for Red Garnet Mustard Seeds to grow to harvestable height. But you can grow them one until the true leaf stage. So the harvest time for these microgreens is between days 10 and 30 days.

These mustard microgreens are great to use fresh in spring rolls, sandwiches, stir fry, or dishes where you want some spice.

The Red Garnet Mustard microgreens will add a zing to your sandwiches and salads.

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

Some people like these red garnet microgreens as they develop true leaves. We prefer to eat them in the cotyledon stage.
