When to Plant Bok Choy in Alaska

Growing Bok Choy in Alaska: Complete Guide

Bok Choy (Brassica rapa subsp. chinensis) is a crop that grows best when sown directly in the garden. In Alaska, the right time to direct sow is around Monday, April 12, 2027, once soil temperatures are consistently warm enough for germination.

Because Alaska stretches across 16 USDA hardiness zones (1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 45 days to maturity, Bok Choy fits comfortably within Alaska's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Bok Choy requires partial shade to full sun and regular (consistent moisture) moisture. Alaska's long summer days accelerate growth, but frost can arrive early in August — season extension with row covers is essential.
