How to Grow Dill
Dill
Anethum graveolens
herbDill is a delicate, feathery annual herb with thin, hair-like leaves and distinctive flat-topped yellow flower clusters called umbels. It's prized for both its aromatic leaves (fronds) and small seeds, which are used extensively in cooking and pickling. The plant grows tall and slender, typically reaching 24-36 inches in height.

Growth Stages
Germination & Seedling
7-14 days germination; 2-3 weeks to thinning stageTiny seedlings emerge with thread-like cotyledons and first true leaves appearing feathery. Plants are delicate and vulnerable.
Keep soil consistently moist but not soggy. Thin seedlings to 9 inches apart when 2-3 inches tall. Protect from wind if possible. Avoid transplanting.
Vegetative Growth
3-4 weeksPlant develops multiple feathery fronds and grows taller, becoming a sturdy herb plant. Foliage becomes increasingly dense and aromatic.
Water regularly to maintain moist soil. Pinch off flower buds if harvesting only leaves. Stake tall varieties in windy locations. Light fertilization (low-nitrogen) promotes leaf growth.
Flowering
2-3 weeksPlant produces tall, slender flower stems with distinctive flat-topped yellow umbel flower clusters (clusters of tiny yellow flowers). Plant height peaks.
Allow flowers to develop if harvesting seeds. Continue regular watering. Flowers attract beneficial pollinators. Reduce leaf harvesting once flowering begins.
Seed Development & Maturation
3-4 weeksYellow flowers fade and develop into small, flat, oval seeds with characteristic ridges. Seeds gradually change from green to brown and dry down.
Stop watering once seeds begin drying. Allow seeds to mature fully on the plant. Cut seed heads when they turn brown and dry. Hang upside down in paper bags to complete drying.
Harvest Ready
Ready to harvestSeeds are completely dry and brown, separating easily from the seed head. Leaves and stems are fully mature.
Harvest seeds when fully brown and dry. Store in airtight containers. Plant bolts and will decline after seed production; succession plant for continuous leaf harvests.
Common Pests
-
Hand-pick caterpillars in early stages. Allow natural predators like parasitic wasps. Remove affected foliage if infestation is heavy. Netting can prevent adult butterflies from laying eggs.
-
Spray with strong water stream to dislodge. Use insecticidal soap or neem oil if severe. Encourage natural predators like ladybugs and lacewings.
-
Increase humidity by misting plants. Spray with insecticidal soap or horticultural oil. Remove heavily infested leaves.
-
Improve air circulation by spacing plants adequately. Water at soil level, not overhead. Remove infected leaves. Apply sulfur or copper fungicide if severe.

Harvest Tips
For fresh leaves, begin harvesting once plant is 6-8 inches tall by pinching off outer fronds from the top, leaving the center intact. Harvest frequently (every 3-4 days) to promote bushier growth and delay bolting. For seeds, wait until seed heads turn brown and dry (typically 70-90 days), then cut entire seed heads and hang upside down in paper bags to finish drying and catch seeds as they fall. Seeds store well for 2-3 years in airtight containers.
