When to Plant Olive Tree in Wyoming

Growing Olive Tree in Wyoming: Complete Guide

Olive Tree (Olea europaea) is a crop that grows best when sown directly in the garden. In Wyoming, the right time to direct sow is around Saturday, May 9, 2026, once soil temperatures are consistently warm enough for germination.

Because Wyoming stretches across 4 USDA hardiness zones (4a, 4b, 5a, 5b), planting windows can shift by as much as two to four 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 Wyoming'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. Mountain-state gardens contend with short seasons and intense UV at elevation — cold nights can persist well into June at higher altitudes.
