Growing Arugula: Quick, Spicy Greens for Salads & More

Arugula (Eruca vesicaria), also called rocket or roquette, is a fast-growing, cool-season leafy green with a peppery-nutty flavor. Ready in 4 weeks, it’s perfect for beginners and succession planting.

Growing Basics

• Season: Early spring, late summer/fall. Bolts in heat (>75°F).
• Light: 4–5 hours sun; tolerates light shade.
• Soil: Rich, moist, well-drained. pH 6.0–7.0.
• Container: 6+ inches deep; quality potting mix + compost.

Sowing & Establishment

1. Sow seeds ¼ inch deep, 1 inch apart. Rows 6 inches apart.
2. Water gently; keep moist until germination (5–7 days).
3. Thin to 4–6 inches for mature plants; eat thinnings.
4. Mulch lightly to retain moisture, suppress weeds.

Harvest Strategies

• Cut-and-come-again: Snip outer leaves at 2–3 inches; plant regrows.
• Whole plant: Pull at 4–6 weeks before flowering.
• Flavor: Young leaves = mild; older = spicy. Flowers edible, peppery.
• Harvest morning for crispness.

Season Extension

• Shade cloth in late spring delays bolting.
• Row covers in fall extend harvest into winter.
• Succession sow every 2–3 weeks.

Seed Saving

Let a few plants flower. When seed pods dry brown, bag heads, collect seeds. Store cool/dry in labeled jar. Viable 3–5 years.

Pests & Diseases

• Flea beetles: tiny holes. Row covers, diatomaceous earth, neem.
• Bacterial leaf spot: certified seed, rotate, avoid overhead water.
• Downy mildew: spacing, airflow, resistant varieties.
