When to Plant Serviceberry in Washington

Growing Serviceberry in Washington: Complete Guide

Serviceberry (Amelanchier canadensis) is a crop that grows best when sown directly in the garden. In Washington, the right time to direct sow is around Friday, February 6, 2026, once soil temperatures are consistently warm enough for germination.

Because Washington stretches across 9 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b), 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 1095 days to maturity, Serviceberry fits comfortably within Washington's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Serviceberry requires full sun to partial shade and moderate (1 inch/week) moisture. The Pacific Northwest's cool, wet springs delay soil warm-up; raised beds and black plastic mulch help jump-start the season.
