How to Grow Red Giant Mustard from Seed

Mustard plant is a cool-hardy favorite best sown direct 4-6 weeks before the final frost date or can be started indoors for transplants. Sow 3-4 seeds .5" deep and 2-3" apart in fertile, well-drained soil in full sun to part shade. Seeds germinate in 4-7 days, thinning to 1 plant every 12-18" in the garden once true leaves establish. Harvest large outer leaves, allowing smaller leaves to continue to mature. Provide midsummer shade in warmer climates. It can also be grown for the microgreen and baby leaf stages.

Your mustard crop will give off a peppery scent and spicy flavor with hints of tang. Similar to kale, Mustard continues growing leafy greens through the season. As the warm temperature rises, Red Giant Mustard will bloom yellow flowers before setting seed.

Although tolerant to diseases, monitor regularly for aphids, flea beetles, slugs, and caterpillars.

Mustard leaf features a wide selection of color, flavor, and leaf types such as classic broadleaf, curly, and mizuna. As a cover crop, mustard is sown in the fall to repair and replenish depleted and hardened soils, only to be mulched back into the spring garden as an all-natural Organic "“green" fertilizer.

Harvesting Red Giant Mustard

Most varieties of mustard are ready for harvest about 80 days from sowing. Like other Brassicas such as kale, broccoli, and collards, mustard leaf is a "“cut and come again" crop able to produce well into the frost. Carefully cut outermost leaves from the stem while leaving rest of the plant intact.

Mustard can be left in the garden to easily reseed for next season. Sow mustard in the fall to overwinter and till back into the soil for a springtime nitrogen-rich Organic fertilizer.

Mustard greens may be harvested throughout the season, as long as they are sprouting. As a rule of thumb, it is important to never harvest more than 1/3 to 2/3 of the plant at one time, so that it will continue to grow. If you want to continue growing leaves longer, pluck off the flowers as they come in. Once the flowers blossom, the leaves will no longer grow.
