Arugula Serrated Leaf

Eruca vesicaria subsp. sativa

vegetable

Serrated leaf arugula is a peppery salad green with deeply lobed, saw-toothed leaves that are more ornamental and flavorful than standard arugula varieties. This cool-season crop grows quickly and is ideal for fresh eating, delivering a distinctive spicy bite to salads and dishes. It's a prolific producer that can be harvested repeatedly throughout the growing season.

📅
Days to maturity: 30-50 days from seed to first harvest
🌱
Planting depth: Plant seeds 0.25-0.5 inches deep; direct sow or transplant seedlings

Soil

Type: Well-draining loamy soil rich in organic matter

Growth Stages

1

Germination

5-10 days

Seeds sprout and develop first true leaves; seedlings are delicate and small

Keep soil moist; maintain temperature between 50-65°F; thin seedlings to proper spacing once they develop first true leaves; provide gentle air circulation

2

Seedling/Vegetative Growth

2-3 weeks

Young plants develop characteristic serrated leaves; foliage becomes increasingly distinctive with deep lobing

Water consistently; begin light fertilizing every 2-3 weeks with diluted fertilizer; ensure adequate light to prevent leggy growth; monitor for pests

3

Leaf Development

2-3 weeks

Plant establishes robust leaf rosette with fully serrated, deeply lobed foliage at ideal texture and size for harvest

Continue regular watering; harvest outer leaves to encourage continued growth; remove any yellowing or damaged foliage; maintain consistent moisture to delay bolting

4

Mature/Harvest-Ready

2-4 weeks (can extend with succession planting)

Plant reaches full size with abundant tender leaves ready for cutting; leaves are at peak flavor and texture

Begin regular harvesting of outer leaves; harvest in early morning for best texture; maintain cooler temperatures and consistent moisture to extend harvest window; avoid letting plant fully bolt

5

Bolting/Flowering

1-2 weeks before plant exhaustion

Plant flowers with small white to yellow blooms on elongated stems; leaves become tougher and more peppery

Once bolting begins, quality declines; remove flowering stems to extend leaf harvest briefly; consider replanting with fresh seeds for continuous supply; spent plants can be composted

Common Pests

  • Use row covers on young plants; spray neem oil or insecticidal soap; encourage beneficial insects; trap crops with mustard greens

  • Strong spray of water to dislodge; insecticidal soap; neem oil; encourage natural predators like ladybugs and parasitic wasps

  • Hand-pick caterpillars; Bacillus thuringiensis (Bt) spray; spinosad; row covers to prevent egg-laying

  • and

    Hand-pick early morning or evening; beer traps; diatomaceous earth barriers; copper tape; encourage ground beetles and other predators

  • Yellow sticky traps; strong water spray; insecticidal soap; neem oil; reflective mulches

Harvest Tips

Begin harvesting outer leaves once plant reaches 6-8 inches tall, typically 30-50 days from planting. Use the cut-and-come-again method, removing outer leaves at the base while leaving center to continue growing. Harvest in early morning for crispest, most flavorful leaves. Leaves are best harvested young and tender before flowering; older leaves become tougher and more peppery. Can harvest entire plant at once by cutting 1 inch above soil surface, which may prompt regrowth.

Fun Facts

  • 🌱 Serrated leaf arugula is sometimes called 'Roquette' or 'Rucola' in European cuisines, where it has been cultivated for centuries, particularly around the Mediterranean.
  • 🌱 The spicy, peppery flavor in arugula comes from glucosinolates and isothiocyanates—the same compounds that give mustard and wasabi their characteristic heat.
  • 🌱 Arugula was used in ancient Rome as both a culinary ingredient and an aphrodisiac, valued for its peppery taste and purported romantic properties.
