Growing Olive Tree in Washington: Complete Guide

Olive Tree (Olea europaea) is a crop that grows best when sown directly in the garden. In Washington, the right time to direct sow is around Friday, March 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 1825 days to maturity, Olive Tree 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.

Olive Tree requires full sun (6-8 hours) and low (drought tolerant) moisture. Most of Washington receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
