Growing Guide: Mustard Greens

Overview

Mustard greens are fast-growing cool-season leaf crops prized for their vibrant green leaves and peppery flavor. They’re easy to grow, tolerant of light frost, and useful both as tender baby greens and full-size cooking greens. Mustard also pairs well in mixed salad greens for a zesty kick.

Before Planting

Choose fertile, well-drained soil in a sunny site. Mustard grows best when temperatures stay cool — early spring and fall are ideal. Work compost into the planting area to provide nutrient-rich soil.

Planting

Direct sow seeds outdoors once soil temperatures reach 45–50°F. Sow seeds ½ inch deep in rows spaced 12–18 inches apart, with plants 8–12 inches apart within rows. Thin seedlings as they emerge if needed. For early starts, sow indoors 3–4 weeks before transplanting.

Watering

Mustard greens prefer consistent moisture but do not tolerate waterlogged soil. Water deeply once or twice a week depending on rainfall and temperature.

Fertilizing

Incorporate balanced fertilizer or aged compost into soil before planting. A side-dressing of organic fertilizer mid-season can support vigorous leaf growth.

Days to Maturity

Old Fashioned Mustard Greens typically mature in about 40–50 days, depending on conditions and planting date.

Harvesting

Harvest outer leaves when young and tender or cut entire plants at full size. For baby greens, start harvesting when leaves are a few inches long.

Growing Tips

Succession sow every 2–3 weeks for a steady supply. Mulch helps conserve moisture and regulate soil temperatures. Light frost enhances the flavor of mustard greens.
