Seedling
2-3 weeksTiny, feathery seedlings emerge within 7-10 days; delicate foliage appears needle-like and pale green.
Keep soil consistently moist but not soggy. Thin seedlings to proper spacing once they have 2-3 true leaves. Protect from strong winds.
Vegetative Growth
3-4 weeksPlant develops characteristic fine, feathery leaves in a compact mound; foliage becomes increasingly ornamental and full.
Water regularly and maintain even moisture. Begin harvesting outer leaves once plant is 6 inches tall. Pinch flower buds if you want to extend leaf production.
Flowering
2-3 weeksDelicate, tiny yellow flowers appear in flat-topped umbel clusters atop the fern-like foliage.
Allow flowers to develop if you want seed production. Flowering signals the plant will soon decline. Plants attract beneficial insects, especially pollinators.
Seed Production
3-4 weeksYellow flowers give way to seed pods that transition from green to brown; seeds dry and ripen on the plant.
Stop watering once seeds begin to mature to encourage drying. Harvest seed heads when they turn brown and rattle when shaken.
Maturity/Decline
VariablePlant slows growth, foliage may yellow, and seeds are fully dry and ready for harvest or self-sowing.
Cut seed heads into a paper bag to collect seeds. Allow to air-dry fully before storage. Plants are typically removed after this stage.

Harvest Tips
Harvest leaves anytime after plant is 6 inches tall by pinching or cutting from the outside in; this encourages bushiness. Harvest seed heads when they turn brown and dry, usually 70-90 days after planting. Cut entire seed head and hang in a paper bag to dry further. For best leaf flavor, harvest in the morning after dew dries. Young, tender leaves have superior flavor. Fernleaf dill is excellent for container harvesting, allowing you to cut individual sprigs as needed throughout the season.
