Germination
1-2 weeksSeeds sprout and first cotyledons (seed leaves) emerge, appearing as thin green shoots.
Keep soil consistently moist but not waterlogged. Maintain warm soil temperature (60-70°F). Germination takes 7-14 days.
Seedling
2-3 weeksTrue leaves develop with characteristic feathery texture; plant becomes recognizable as dill with fine, thread-like foliage.
Provide bright light to prevent leggy growth. Thin seedlings to 12 inches apart. Keep soil moist but not soggy.
Vegetative Growth
3-4 weeksPlant develops full bushy form with dense, fern-like foliage. Compact growth remains 12-18 inches tall.
Pinch off flower buds if harvesting only leaves. Water consistently. Light fertilization with balanced fertilizer monthly.
Flowering
2-3 weeksSmall, delicate yellow flowers appear in umbrella-like clusters (umbels) at stem tips.
Allow flowers to develop if you want seeds. Reduce watering slightly. Flowers attract beneficial pollinators.
Seed Production & Harvest
2-4 weeksFlowers fade and develop into small, flat, ridged seeds that turn brown when mature.
Allow seeds to dry on plant before harvesting. Cut seed heads into paper bags. Seeds are ready when they separate easily from the stem.

Harvest Tips
For fresh foliage: Begin harvesting leaves once plant is 6-8 inches tall, pinching off top growth to encourage bushiness. Harvest in morning after dew dries for best flavor. For seeds: Allow flowers to mature and dry on plant until seeds turn brown (typically 4-6 weeks after flowering). Cut seed heads and hang upside down in a paper bag or over a tray to catch seeds. Seeds are ready when they fall freely from the seed head.
