Growing Tips

  • Arugula is ready in 30–40 days — one of the fastest salad greens.
  • Young leaves are mild; older leaves become peppery — harvest young for salads.
  • Direct sow in cool weather — spring and fall are ideal.
  • Partial shade in summer slows bolting significantly.
  • Let a plant flower and go to seed — arugula self-sows readily.

Common Mistakes

  • Planting in summer heat — bolts within days above 75°F.
  • Letting plants get too big before harvesting — peppery bitterness intensifies.
  • Not succession planting — sow every 2–3 weeks through spring and fall.
  • Transplanting — direct sow only for best results.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
