Growing Plum Tree in Oregon: Complete Guide
Plum Tree (Prunus domestica) is a crop that grows best when sown directly in the garden. In Oregon, the right time to direct sow is around Sunday, February 1, 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 1460 days to maturity, Plum Tree 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.
Plum Tree requires full sun (6-8 hours) and moderate (1 inch/week) 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.
