When to Plant Dill for the USDA Zones of the U.S.

Planting Dill ( Anethum graveolens) in the right timeframe is essential for successful growth. Here’s Johnny Butterflyseed’s general guideline for planting dill in USDA zones 3 to 10. Keep in mind that local weather conditions, soil type, and other factors can influence the best planting times.

USDA Zone 3

  • Spring: Late April to early May, after the last frost date.
  • Fall: Not recommended due to a shorter growing season.

USDA Zone 4

  • Spring: Mid to late April, after the last frost date.
  • Fall: Not recommended.

USDA Zone 5

  • Spring: Early to mid-April, after the danger of frost has passed.
  • Fall: Early August for a late harvest.

USDA Zone 6

  • Spring: Late March to early April.
  • Fall: Late July to early August.

USDA Zone 7

  • Spring: Mid to late March.
  • Fall: Mid to late July.

USDA Zone 8

  • Spring: Early to mid-March.
  • Fall: Early to mid-July.

USDA Zone 9

  • Spring: Late February to early March.
  • Fall: Early July.

USDA Zone 10

  • Spring: Mid to late February.
  • Fall: Late June to early July.

Additional Considerations

  • Indoor Planting: In colder zones, starting dill indoors 4-6 weeks before the last expected frost can give plants a head start.
  • Successive Planting: Planting dill every 2-3 weeks during the growing season ensures a continuous supply.

These dates are general guidelines and can vary based on specific local conditions. It’s advisable to consult local gardening centers, cooperative extensions, or online planting calendars tailored to your exact location for the most accurate planting dates for dill.
