When to Plant Head Lettuce in Kentucky

Growing Head Lettuce in Kentucky: Complete Guide

Head 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 Kentucky falls between March 8, 2027 (Zone 7b) and March 23, 2027 (Zone 6a), once soil temperatures are consistently warm enough for germination.

Because Kentucky stretches across 4 USDA hardiness zones (6a, 6b, 7a, 7b), 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 70 days to maturity, Head Lettuce fits comfortably within Kentucky's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Head Lettuce requires full sun and regular moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
