Leaf lettuce
Asteraceae · Direct sow · compact garden planning guide
| Bed spacing | 12 × 12 in (304.8 × 304.8 mm) |
|---|---|
| Minimum sun used | 4 hours per day |
| Root depth used | 150 mm (5.9 in) |
| Container volume used | 5 L |
| Spring preparation | -28 to -14 days from your last frost |
| Maturity estimate | 45–60 days from sowing |
Square bed spacing, root-space thresholds, relative spring offsets and seed quantities are selected planning parameters, not universal cultivar rules. Maturity ranges are planning estimates; follow your packet or nursery label.
Before planting
Avoid heat and bolting; sow only in workable soil.
Establish
Mist the surface gently; small seeds must not be washed away.
Tend and harvest
Check the growing center and take small outer leaves without uprooting the plant. Pick usable outer leaves before bitterness or a flowering stalk develops.

Full-size leaf lettuce plant distance is 10–12 inches. Our 12-inch square cells use an intensive bed layout rather than conventional row aisles.

Sun exposure, drainage, growing media and crop-specific minimum volumes; our thresholds are conservative planning settings.

Cool and warm season establishment; weather and soil readiness matter. Minnesota month dates are not used as global dates.

Maturity is a cultivar-dependent estimate; our extra 14-day fall buffer is an explicit planning assumption.
