Growing Details

Zone Performance
Dill grows as a fast-cycling annual throughout its full Zone 3-11 range, so zone mainly determines timing and number of successions possible: cold Zone 3-5 gardens get one or two plantings before frost ends the season, while warm Zone 9-11 gardens can direct-sow dill in fall and winter as well as spring, since it bolts quickly once summer heat arrives everywhere.
Companions & Wildlife
🦌 Deer Resistance
seldom damaged
Dill's pungent, feathery foliage is generally passed over by deer in favor of more palatable garden plants.
🐝 Pollinator Value
high
Dill's flat-topped yellow flower umbels attract hoverflies, parasitic wasps, ladybugs, and are a favored host plant for black swallowtail butterfly caterpillars.
Good Companions
Broccoli — Dill's flowers attract parasitic wasps and other predatory insects that prey on cabbage worms and other brassica pests.
Cabbage — Dill's flowers attract parasitic wasps and other predatory insects that prey on cabbage worms and other brassica pests.
Kale — Dill's flowers attract parasitic wasps and other predatory insects that prey on brassica pests.
Troubleshooting
⚠️ Bolting to seed quickly in hot weather, ending leaf production
Succession sow every 3-4 weeks through the cool season and harvest leaves promptly before flower heads form.
⚠️ Toppling over in wind or rain due to tall, hollow stems
Plant in a sheltered spot or stake tall varieties, and avoid overly rich soil that produces excessively soft, weak growth.
⚠️ Parsleyworm (black swallowtail caterpillar) defoliating plants
Tolerate moderate feeding to support butterfly populations, or plant extra dill specifically as a sacrificial host plant.
⚠️ Transplant shock and bolting when started indoors and moved outside
Direct sow dill whenever possible, since its taproot resents disturbance and disturbed seedlings often bolt prematurely.
