🌿 About Leaf Lettuce
Growing Leaf Lettuce in Utah: Complete Guide
Leaf Lettuce (Lactuca sativa) is a crop that grows best when sown directly in the garden. In Utah, the right time to direct sow is around Saturday, March 28, 2026, once soil temperatures are consistently warm enough for germination.
Because Utah stretches across 9 USDA hardiness zones (4a, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b), 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 Utah'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. Most of Utah receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
