History & Nutrition

History

Dill (Anethum graveolens) has been cultivated for over 5,000 years, with origins likely in the Mediterranean region and western Asia. Ancient Egyptians used dill medicinally, and the herb appears in the Ebers Papyrus (circa 1500 BCE), one of the oldest surviving medical texts. The Romans considered dill a symbol of good luck, while gladiators rubbed dill oil on their skin before combat believing it would bring victory. The name "dill" derives from the Old Norse "dilla" meaning "to soothe" or "to lull," reflecting the herb's long history as a remedy for digestive complaints and colicky babies—"gripe water," a traditional infant colic remedy, traditionally contained dill. In medieval Europe, dill was believed to have magical properties: it was thought to protect against witchcraft and evil spells when worn or hung in doorways. The herb became particularly important in Scandinavian, German, Polish, and Russian cuisines, where it remains essential to iconic dishes from gravlax to borscht. Jewish dill pickles, developed by Eastern European immigrants in New York City in the late 19th century, became quintessentially American delicatessen fare. Both the feathery leaves (dill weed) and the seeds (dill seed) are used in cooking, with the leaves offering a fresher, grassier flavor while the seeds provide a more concentrated, slightly bitter taste.

Climate & Temperature

Optimal Growing Temp

60°F - 70°F

Dill prefers cool weather and grows best in spring and fall. Hot weather (above 80°F) causes rapid bolting to seed, ending leaf production. In warm climates, grow dill in partial shade or as a fall/winter crop.

Survival Range

50°F - 85°F

Can survive these temperatures

semi hardy
cool Season

Frost Note: Tolerates light frosts (down to 25°F) but is killed by hard freezes. Can overwinter in mild climates (zones 8-10) if planted in late summer/fall.

Best USDA Zones

Zone 3Zone 4Zone 5Zone 6Zone 7Zone 8Zone 9

Humidity

40-60%

Tolerates a wide range of humidity. In very humid climates, ensure good air circulation to prevent fungal issues. Avoid overhead watering.

Plant Size & Growth

Height

24-36 inches

Spread

12-18 inches

Growth Habit

upright

annualRoot Depth: Deep taproot (12-18 inches) makes dill difficult to transplant. Direct sow where plants will grow.
Growth Stages

Germination

7-14 days

Tiny thread-like seedlings emerge. Look delicate but grow quickly once established.

Seedling Stage

Duration: 2-3 weeks

True leaves: First true leaves are feathery and fern-like, distinctly dill-scented when touched.

Transplant ready: Not recommended—taproot makes transplanting difficult. Direct sow instead.

Vegetative Growth

Duration: 4-6 weeks

Rapid growth of feathery foliage. Harvest leaves anytime during this stage for best flavor. Plant stays compact and bushy if kept well-watered and cool.

Flowering

Timing: 6-10 weeks from sowing

Duration: 2-3 weeks

Umbrella-shaped yellow flower clusters attract beneficial insects, swallowtail butterflies, and pollinators. Self-fertile.

Harvest Maturity

Timing: 65-90 days for seed harvest

  • Flower heads turn brown
  • Seeds develop flat, oval shape
  • Plants begin to decline after seed formation
Expected Yield

Per Plant

4-8 ounces of fresh leaves per plant over harvest season; 2-3 tablespoons of seeds per flower head.

Per Square Foot

1-2 plants per square foot for leaf harvest; space wider (1 plant per 1.5 sq ft) for seed production.

Harvest Frequency

Harvest leaves continuously every few days. For seeds, harvest once when seed heads turn brown.

Factors Affecting Yield

  • •Cool weather extends leaf production
  • •Heat triggers rapid bolting
  • •Consistent moisture delays flowering
  • •Succession planting ensures continuous supply
Watering Guide

Seedling Stage

Keep soil consistently moist but not waterlogged. Water gently to avoid displacing delicate seedlings. Mist if surface dries.

Established Plants

Water deeply when top inch of soil is dry—typically every 3-4 days. Consistent moisture prevents premature bolting.

During Fruiting

If growing for seeds, reduce watering slightly once flowering begins to concentrate flavor in seeds.

Preferred Method

Water at soil level to keep feathery foliage dry. Drip irrigation or soaker hoses ideal. Avoid overhead watering which can promote fungal disease.

Pro Tips

  • Morning watering allows foliage to dry before evening
  • Mulch lightly to maintain even soil moisture and cool roots
  • Drought stress triggers immediate bolting
  • In hot climates, water daily to keep plants producing leaves
Fertilizing Guide
light feederRecommended: 5-10-5 or balanced

Feeding Schedule

Planting

Compost or balanced organic fertilizer mixed into soil

Once at planting

Vegetative growth

Light liquid fertilizer or compost tea

Every 3-4 weeks if needed

Flowering/seed production

None—excess nitrogen reduces seed flavor

Stop fertilizing

Organic Options

CompostWorm castingsFish emulsion (diluted)Compost tea

Side-dress with compost or apply diluted liquid fertilizer. Dill needs minimal feeding—overfertilizing produces lush foliage but weak flavor.

Container Growing
âś“ Suitable for containers

Minimum Size

10 inch pot

Recommended Size

12-14 inch pot

Depth Required

At least 12 inches deep for taproot

Best Varieties for Containers

FernleafBouquet

Container Tips

  • Use deep pots to accommodate the taproot
  • Dwarf varieties like "Fernleaf" are more suited to containers
  • Place in cool location; containers heat up quickly in sun
  • Water daily in hot weather to prevent bolting
  • Harvest frequently to delay flowering
Succession Planting

Plant Every

Every 2-3 weeks

Sowings/Season

4-6 plantings for continuous leaf harvest

Duration

Plant from early spring through early summer in cool climates; spring and fall in hot climates

Tips

  • Succession plant for continuous fresh leaves all season
  • First planting bolts quickly; later plantings provide backup
  • In hot climates, stop planting in early summer and resume in late summer
  • Final planting can be allowed to flower and set seed
  • Mark succession plantings to track which is ready to harvest
