Jericho

Lettuce

60d to harvest

Jericho lettuce brings a crisp, cool crunch with a delicate, sweet-green flavor and a tender bite that stays pleasantly snappy. At maturity, heads form with a softly ruffled texture and a fresh, clean finish—ideal for gardeners who want a reliable, garden-fresh centerpiece for everyday salads and bright garnishes. Grow Jericho for a satisfying harvest window around 60 days, when the leaves are at their most luminous and crisp.

Frequently Asked Questions

How often should I water Lactuca sativa during its main growth phase to prevent bitter or stressed heads?

During the ~3–6 weeks of active leaf growth (leading up to harvest), keep soil evenly moist—not soggy—so the root zone stays consistently damp. Water deeply about 2–3 times per week depending on heat, aiming for roughly 1 inch per week total, and adjust to more frequent watering during hot spells. If you let the soil dry out and then soak again, lettuce can turn bitter and bolt more readily.

How do I tell when Jericho (Lactuca sativa) is ready to harvest?

Harvest when heads/leaf rosettes are firm and reach the expected size for your spacing, typically around 60 days from sowing. For best flavor, pick in the morning when leaves are crisp, and avoid waiting until plants look overgrown or start stretching upward (a sign of bolting). If it’s heading, harvest just as the outer leaves fit snugly; if it’s loose-leaf type, cut outer leaves once they’re fully sized while the center continues growing.
