When to Plant Celery in Alaska

Growing Celery in Alaska: Complete Guide

Celery (Apium graveolens) is a warm-season crop that needs a head start indoors before Alaska's last frost. Most Alaska gardeners begin seeds indoors around Sunday, March 1, 2026 and move transplants outside around Sunday, May 24, 2026, after the risk of frost has passed.

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 130 days to maturity, Celery needs the indoor head start that Alaska's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Celery requires full sun and regular moisture. Alaska's long summer days accelerate growth, but frost can arrive early in August — season extension with row covers is essential.
