When to Plant Leaf Lettuce in Oregon

Growing Leaf Lettuce in Oregon: Complete Guide

Leaf Lettuce (Lactuca sativa) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Oregon falls between January 13, 2027 (Zone 9b) and March 28, 2027 (Zone 5b), 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 45 days to maturity, Leaf Lettuce 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.

Leaf Lettuce requires full sun and regular moisture. The Pacific Northwest's cool, wet springs delay soil warm-up; raised beds and black plastic mulch help jump-start the season.
