Alaska Planting Calendar
Month-by-month planting calendar for Alaska. 143 crops with sow windows for a subarctic, short cool summer, long daylight climate.
Monthly Planting Calendar
Alaska's populated areas (Anchorage and the railbelt, USDA 3-5) have long, cold winters and a short, cool summer of roughly 100-115 frost-free days, but extremely long midsummer daylight that drives fast growth and famously large cool-season vegetables. Hardy crops (brassicas, roots, greens, peas, potatoes) are sown from May once the soil thaws; frost-tender crops like tomatoes go out in June and usually do best in a tunnel or greenhouse. Garlic is planted in fall under mulch. Last frost is typically mid-to-late May and the first fall frost around mid-September. These windows are a first-pass estimate from UAF Cooperative Extension and are being reviewed locally.

What grows well in Alaska?
Cool-season crops shine: cabbage, kale, broccoli, lettuce, carrots, beets, peas and potatoes grow fast and large under the long summer daylight. Sow from May; warm crops need a tunnel.
How short is the season?
Roughly 100-115 frost-free days. Start long-season crops indoors and transplant after the mid-to-late May last frost; most sowing is done by July.
How accurate are these dates?
A careful first pass based on UAF Cooperative Extension guidance, under local review.
