Growing carrots in zone 1
Carrot seed is slow to germinate; keep the bed evenly moist for up to two weeks (a board over the row helps). Thin ruthlessly to 2 inches. Fall carrots left in the ground through frosts get noticeably sweeter.
Zone 1 covers interior and Arctic Alaska — extremely short season — most crops need transplants, season extension, or a greenhouse. Zone dates are medians: frost timing varies within a zone with elevation and terrain, so treat these windows as a solid default and refine them with your own city’s dates below.

These windows use zone 1's typical frost dates (last frost ~Jun 15, first frost ~Aug 25). For windows computed from your frost dates, run the ZIP code frost lookup and open the planting calendar — it remembers your city. The seed starting scheduler turns the whole seed rack into one printable, date-sorted list.
Frequently asked questions
When do I plant carrots in zone 1?
Direct sow May 25 – Jun 15, counted from zone 1's typical last frost around Jun 15. As a hardy crop it tolerates the light frosts on either side of that window.
Can I direct sow carrots in zone 1?
Yes — direct sow May 25 – Jun 15. This crop prefers direct sowing; its roots dislike transplanting.
Can I plant carrots for a fall harvest in zone 1?
Yes — sow Jun 2 – Jun 16, counted back from the typical Aug 25 first frost so plants mature before serious cold. Light fall frosts improve flavor rather than ending the crop.
