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
