Growing Blueberry in Oregon: Complete Guide

Blueberry (Vaccinium corymbosum) is a crop that grows best when sown directly in the garden. In Oregon, the right time to direct sow is around Sunday, February 15, 2026, once soil temperatures are consistently warm enough for germination.

Because Oregon 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 730 days to maturity, Blueberry fits comfortably within Oregon's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Blueberry requires full sun and regular moisture. Most of Oregon receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
