How to Grow Dill

Dill (Anethum graveolens) is a fragrant annual herb valued for its feathery foliage, flavorful seeds, and usefulness in pickling. It thrives in full sun, well-drained soil, and adapts easily to a wide range of climates. This guide explains planting, germination, care, harvesting, and climate considerations suitable for all regions.

Where Should You Plant Dill?

  • Best location: Full sun; dill grows tall and produces the most foliage with strong light.
  • Soil: Well-drained, moderately fertile soil; pH 5.5–7.0.
  • Moisture: Moderate moisture; avoid soggy soil to prevent root issues.

When Should You Plant Dill?

  • Start indoors: Optional; dill prefers direct sowing but can be started 2–3 weeks early if needed.
  • Transplanting: Move outdoors once temperatures support steady growth and the risk of cold damage has passed.
  • Direct sow: Plant when soil is workable and warm enough for germination; suitable for repeated sowings.

How Do You Plant Dill?

  • Depth: Sow seeds ¼ inch deep; germination typically occurs within 7–14 days.
  • Spacing: Space plants 12–18 inches apart; dill grows tall and airy.
  • Quantity: Several plants provide continuous foliage and seed production.

Which Plants Grow Well With Dill?

  • Companions: Lettuce, onions, cucumbers, and herbs that enjoy similar moisture levels.
  • Avoid: Carrots and fennel; they may cross-interfere with growth or flavor.
  • Best pairing: Flowers that attract pollinators and beneficial insects.

How Do You Water and Feed Dill?

  • Watering: Maintain steady moisture during early growth; mature plants tolerate brief dryness.
  • Feeding: Apply compost or a light organic fertilizer; excessive fertility may reduce aroma intensity.

How Do You Care for Dill?

  • Support: Tall varieties may require staking in windy conditions.
  • Weeding: Keep beds weed-free to reduce competition and maintain airflow.

Can You Grow Dill in Containers?

  • Container size: Minimum 8–10 inches deep and wide; dill grows well in pots.
  • Winter growing: Grow indoors in bright windows or under lights during cool seasons.

What Pests or Diseases Affect Dill?

  • Pests: Aphids, caterpillars, and leaf miners; monitor foliage and use organic controls if needed.
  • Diseases: Powdery mildew and leaf spot in humid conditions; ensure good airflow and avoid overhead watering.

How Do You Harvest Dill?

  • Timing: Harvest foliage once plants reach 8–12 inches; seeds mature later in the season.
  • Leaves: Snip fresh leaves as needed; regular harvesting encourages new growth.
  • Seeds: Allow flower heads to dry on the plant; collect seeds once umbels turn brown.
