How to Grow Parsley

Parsley (Petroselinum crispum) is a versatile biennial herb grown for its fresh, flavorful leaves. It thrives in full sun to partial shade, moist soil, and cool to moderate temperatures. This guide explains planting, germination, care, harvesting, and climate considerations suitable for all regions.

Where Should You Plant Parsley?

  • Best location: Full sun to partial shade; parsley tolerates lower light better than many herbs.
  • Soil: Moist, well-drained, nutrient-rich soil; pH 6.0–7.0.
  • Moisture: Consistent moisture; parsley prefers evenly damp soil.

When Should You Plant Parsley?

  • Start indoors: Begin seeds 8–10 weeks before transplanting; parsley germinates slowly.
  • Transplanting: Move outdoors once temperatures are mild and frost danger has passed.
  • Direct sow: Plant when soil is warm enough for steady germination.

How Do You Plant Parsley?

  • Depth: Sow seeds ¼ inch deep; germination may take 2–4 weeks.
  • Spacing: Space plants 8–12 inches apart for full leaf production.
  • Quantity: Several plants ensure continuous harvest throughout the season.

Which Plants Grow Well With Parsley?

  • Companions: Tomatoes, peppers, chives, and basil.
  • Avoid: Plants that require very dry soil.
  • Best pairing: Moisture-loving herbs and vegetables that enjoy similar conditions.

How Do You Water and Feed Parsley?

  • Watering: Keep soil evenly moist; parsley wilts quickly in dry conditions.
  • Feeding: Apply compost or balanced fertilizer to support leafy growth.

How Do You Care for Parsley?

  • Support: No support needed; plants form natural clumps.
  • Weeding: Keep beds weed-free to reduce competition and maintain soil moisture.

Can You Grow Parsley in Containers?

  • Container size: Minimum 8–10 inches deep; parsley grows well in pots.
  • Winter growing: Possible indoors with bright light; parsley adapts well to indoor conditions.

What Pests or Diseases Affect Parsley?

  • Pests: Aphids, caterpillars, and spider mites.
  • Diseases: Leaf spot and root rot; ensure good airflow and proper watering.

How Do You Harvest Parsley?

  • Timing: Harvest once plants are well-established; flavor is strongest in cool weather.
  • Leaves: Pick outer stems first; regular harvesting encourages new growth.
  • Seeds: Collect seeds from mature flower heads in the second year.
