Growing Dill in Zone 4B

Dill is an easy, self-seeding herb essential for pickles, fish, and potato dishes.

Zone 4B has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Direct sow — dill doesn’t transplant well due to its taproot
• Will self-seed and come back year after year
• Harvest leaves (dill weed) before flowers appear for best flavor
• Let some plants flower for seeds and to attract beneficial insects
• Fernleaf variety stays compact and is great for containers

Companion Planting

Good companions: cabbage, onions, lettuce, cucumbers

Avoid planting near: carrots (cross-pollination risk), tomatoes

Harvest Timeline

40-60 days for leaves; 85 days for seed heads
