Growing Dill: A Complete Profile

By Growing Home Greens Team · July 18, 2026

Dill is an easy, low-maintenance herb that mostly takes care of itself once it’s in the ground — the main thing to get right is where you plant it, since mature dill doesn’t get along with one of the garden’s most common root crops.

What to expect

Direct-sow seed about 1/4 inch deep roughly a week before your last frost — dill doesn’t transplant well, thanks to a taproot that resents disturbance. At 4 plants per square foot, it grows quickly, reaching usable size in under two months. Left alone, dill will flower, set seed, and often self-sow for next year, which is a feature if you want a returning patch and a nuisance if you don’t.

Common problems

Dill that bolts almost as soon as it’s established is usually a heat response — like cilantro, dill is a cool-season herb at heart, and hot weather pushes it to flower early at the expense of leaf production. Choosing a slower-to-bolt variety helps but doesn’t eliminate this. Yellowing on lower leaves that spreads upward can be a sign of overly wet soil rather than a nutrient issue.

Where this fits in your garden

Dill attracts beneficial predatory insects that help protect nearby brassicas like cabbage — see the full companion guide for dill. Keep it well away from carrots: mature, flowering dill can inhibit carrot root development and cross-attract shared pests. In the Garden Designer, its self-seeding habit is worth accounting for — a dill patch left to flower will likely come back on its own the following year in the same spot.
