TL;DR
Plant carrots in Anchorage between May 19-June 15 for harvest by September 14. Zone 4b's ultra-short 118-day growing season requires fast-maturing Nantes and Chantenay varieties (65-75 days). Focus on soil warming techniques and succession planting every 2 weeks through June to maximize your harvest window before Alaska's early autumn freeze.
Frequently Asked Questions

When is the latest I can plant carrots in Anchorage?

Plant your final carrot crop by July 5 using ultra-fast varieties like Daucus carota 'Paris Market' that mature in 60 days. This timing allows harvest by September 14 before Alaska's first hard frost. Later plantings risk being caught by freeze before reaching eating size.

Which carrot varieties work best in Anchorage's short season?

Daucus carota 'Scarlet Nantes' and Daucus carota 'Little Finger' perform exceptionally in Zone 4b conditions. Nantes types mature in 65-70 days with excellent cold tolerance, while Little Finger produces baby carrots in just 55 days. Both handle Alaska's temperature fluctuations better than slower varieties.

How do I prevent carrot seeds from failing to germinate in cold Alaska soil?

Pre-warm your planting beds using black plastic sheeting 2 weeks before sowing. Plant seeds 1/4 inch deep and cover rows with boards to maintain consistent soil moisture and temperature. Remove boards immediately when green shoots appear, typically 7-10 days in Anchorage conditions.

Can I grow carrots through winter in Anchorage?

Yes, using in-ground storage techniques. Plant Daucus carota 'Napoli' by early June, allow them to mature by September, then leave in the ground covered with 12 inches of straw mulch and waterproof tarp. Alaska's frozen soil acts as a natural refrigerator, preserving carrots until spring harvest.

What soil preparation is essential for Anchorage carrot success?

Double-dig beds to 12-inch depth and remove all rocks larger than a quarter. Mix in 4 inches of compost and test pH—it should read 6.0-6.8. Alaska's heavy clay soils require this preparation for straight root development. Consider raised beds for improved drainage and faster soil warming.

Tom Erikson

Tom is a lifelong Alaskan who gardens in Anchorage, where the growing season is short but intense. He works for the state cooperative extension service and has spent years figuring out what works in a climate where the ground freezes deep, the growing season starts in late May, and you get 19 hours of daylight in June. Tom grows cold-hardy vegetables, maintains a collection of boreal-adapted perennials, and experiments with season extension using cold frames and row covers. He writes about the realities of northern gardening—the unique advantages (those long summer days produce remarkable growth) and the genuine limitations. Tom's tone is calm and practical, with the quiet humor of someone who's gardened through Alaskan winters for decades.
