Dill is a fast, feathery annual herb that fits the Zone 2 season easily: it matures in 40 to 50 days, tolerates light frost, and self-sows so freely that one year's plants often return as next year's volunteers. Dill is the classic partner for cucumbers, fish, and pickling, and its umbrella-shaped flower heads are also a magnet for beneficial insects. The main Zone 2 challenge is wind — dill grows tall and thin, so give it a sheltered spot or a little support.
This guide covers when to plant dill zone 2 — the sowing and transplanting dates that work in Zone 2, and the soil, spacing, sun, water and care the crop needs. All frost dates below are USDA/NOAA zone averages for Zone 2, not promises for any one garden — check your local extension service, because frost dates vary by microclimate, elevation and year.
Zone 2 at a glance
USDA Zone 2 has average winter lows of −50 to −40°F, an average last spring frost of June 1–15 and an average first autumn frost of August 15–September 1, leaving roughly 60 to 90 frost-free days in an average year. That is one of the shortest growing seasons in the United States, so short-season varieties, indoor starting where the crop allows it, and protection at both ends of the season — a cold frame, cloche or low tunnel — are often the difference between a harvest and an empty bed.

When to plant dill in Zone 2
Sow directly May 4 to June 1, a few weeks before the average last frost of June 1–15 — dill is hardy, so it can handle cool soil and a light frost. With 40–50 days to maturity the harvest falls around June 20–30, comfortably before the average first frost of August 15 to September 1. Frost dates are zone averages — check your local extension service.
The planting calendar hub gives the Zone 2 picture month by month — see June in Zone 2 and July in Zone 2 — and the frost date calculator and seed starting calculator turn your frost averages into sowing dates.
Starting dill in Zone 2
Sow seed directly where it is to grow — dill has a taproot and dislikes transplanting. Sow in mid to late May, once the soil has warmed a little, and keep the seedbed moist until seedlings appear in 7–14 days. Thin to the spacing below and give plants a sheltered spot, because tall dill blows over in a Zone 2 wind. Do not plant dill near carrots or fennel if you can avoid it.
In Zone 2, a raised bed warms earlier than flat ground, and black plastic laid over the bed for a week or two before planting warms the soil further. Harden off indoor-started plants for a week to ten days before they go outside, putting them out for a few hours a day in a sheltered spot and bringing them in if frost is forecast.
Soil, spacing, sun and water
Dill grows best in full sun, in soil with a pH of 5.5–6.5. Test your soil through your local extension service rather than guessing, and dig in well-rotted compost before planting to improve drainage and moisture holding. Space plants 12–18 inches apart — in a short season it is tempting to crowd plants in, but crowded plants stay small and invite disease, so use the plant spacing calculator if you are laying out a bed. Dill needs moderate water: water deeply and less often rather than lightly every day, water at the base in the morning so leaves dry before night, and mulch to keep the soil evenly moist. Check the soil a finger's depth down and water when it feels dry there.
Companion planting
Good companions for dill include tomatoes, peppers, marigolds, cabbage. The companion planting finder can suggest combinations for your whole bed. Avoid planting dill where the same family (Apiaceae) grew last year, and rotate crops each year to reduce soil-borne disease.
Pests and problems
The common pests and problems to watch for with dill are carrot rust fly, aphids, wireworms. Inspect plants regularly, especially the undersides of leaves, and act early: hand-pick larger pests, wash aphids off with a strong jet of water, and remove badly affected leaves rather than waiting for the problem to spread. Healthy plants in the right soil and spacing resist pests better than stressed ones.
Harvest and storage
Pick feathery leaves from about 40 days after sowing, snipping them with scissors. For pickling, cut whole flower heads once the seeds have formed but before they scatter. Dill freezes better than it dries — chop leaves and freeze in ice-cube trays with water. Let a few plants go to seed and they will self-sow for next year. If you dry your harvest, the herb drying calculator helps you work out drying times and yields.

Frequently asked questions
When to plant dill zone 2?
Sow directly May 4 to June 1, a few weeks before the average last frost (June 1–15), for a harvest around June 20–30. These are zone averages — check your local extension service, because frost dates vary by microclimate and year.
Can I grow dill outdoors in Zone 2?
Yes, with the right variety and timing. The frost-free window is roughly 60 to 90 days, so choose short-season varieties and start indoors where the crop allows it. Dill is hardy, so it handles cool weather, but still needs protection from hard frosts.
How long does dill take to grow in Zone 2?
Seeds germinate in 7–14 days, and the crop takes 40–50 days to maturity. In Zone 2, cool soil and cold nights can slow growth, so allow the longer end of the range.
What soil and spacing does dill need in Zone 2?
Dill needs full sun and soil pH 5.5–6.5, spaced 12–18 inches apart. Dig in well-rotted compost, water deeply, mulch, and test your soil through your local extension service.
What pests affect dill in Zone 2?
The main ones are carrot rust fly, aphids, wireworms. Inspect plants regularly and act early, but remember that in Zone 2, cold and wind are usually as big a threat as pests, so keep frost protection ready and choose a sheltered spot.
