🌱 Sow with Confidence—One-Year Seed Guarantee

Mizuna is a Japanese mustard green with feathery, deeply cut leaves and a mild peppery bite. The plants grow quickly in cool weather, forming loose rosettes of tender greens that bring texture and movement to salad mixes without overwhelming the bowl.

Harvest young for baby greens or cut larger leaves for stir-fries, soups, and quick sautés. Mizuna is well suited to cut-and-come-again picking and fall plantings, offering a bright, clean flavor when the garden shifts back toward cool-season crops.

Mustard Green Growing Basics

Mustard greens bring a lively edge to the cool-season garden, their broad leaves carrying flavors that range from gently peppery to bold and bracing. Grown for centuries across Asia, Africa, and Europe, they remain one of the quickest ways to turn a handful of seed into a generous harvest.

Varieties may be smooth, curled, deeply frilled, green, red, or purple. Mustard grows rapidly in cool weather, offering tender baby leaves first and fuller, more strongly flavored greens as the plants mature.

Direct sow mustard greens about 3–5 weeks before the expected last spring frost, once the soil can be worked. Seeds germinate readily in cool soil, and many varieties are ready for baby-leaf harvest in only a few weeks.

Make small sowings every 1–2 weeks while weather remains mild. Sow again in late summer for fall harvest. Mustard tolerates light frost, but sustained heat encourages bolting and gives the leaves a sharper flavor.

Sow seeds about ¼–½ inch deep and keep the seedbed evenly moist until seedlings emerge. Thin plants to 4–6 inches apart for mature leaves, or leave them closer for baby greens.

Mustard is usually best direct sown because it grows quickly and establishes easily. Use the thinnings in salads rather than allowing crowded seedlings to compete.

Choose a site with full sun during cool weather. Light afternoon shade can help extend the harvest as spring temperatures rise.

Grow mustard in fertile, well-drained soil enriched with finished compost. Keep moisture steady so leaves remain tender and growth does not stall. Mulch lightly once plants are established to cool the soil, reduce weeds, and protect soil structure.

Harvest baby leaves once they are large enough to use. For mature plants, pick the largest outer leaves and leave the center growing, or cut the entire plant just above soil level.

Young leaves are mildest and most tender. Harvest promptly as flower stalks begin to rise, since the leaves become tougher and more pungent once plants bolt.
