Growing Info

• When to Plant: Direct sow outdoors in spring after the danger of severe frost has passed and soil can be worked. Dill generally performs best when direct sown because its long taproot dislikes transplanting.
• Planting Depth: Sow approximately ¼ inch deep.
• Spacing: Thin seedlings to approximately 8–12 inches apart once established.
• Row Spacing: Allow approximately 18–24 inches between rows.
• Sunlight: Plant in full sun, ideally receiving at least 6 hours of direct sunlight daily.
• Soil: Grow in loose, fertile, well-draining soil. Avoid overly wet locations.
• Watering: Keep soil consistently moist while seeds germinate and plants establish. Mature plants prefer even moisture without waterlogged soil.
• Succession Planting: Sow small batches every few weeks during suitable weather to maintain a longer supply of fresh dill foliage.
• Harvesting Leaves: Snip fresh foliage as needed once plants are well established.
• Harvesting Flower Heads: Cut mature flower heads for pickling when flowers are fully developed.
• Harvesting Seeds: Allow flower heads to mature and dry on the plant before collecting the aromatic seeds.
