Growing Tips

  • Lettuce is one of the fastest crops — most varieties are ready in 30–45 days.
  • Harvest outer leaves first (cut-and-come-again method) to extend production for weeks.
  • Plant in partial shade during summer to slow bolting.
  • Sow every 2–3 weeks for continuous harvest through spring and fall.
  • Keep soil consistently moist — dry soil causes bitterness and rapid bolting.

Common Mistakes

  • Planting in full summer heat — lettuce bolts (goes to seed) quickly above 75°F.
  • Planting seeds too deep — lettuce needs light to germinate. Press seeds onto the surface.
  • Not thinning seedlings — crowded plants bolt faster and produce less.
  • Skipping fall planting — fall lettuce is sweeter and slower to bolt than spring.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
