Lettuce problems

Keep the shallow root zone consistently moist but not saturated. Check the upper 1–2 cm frequently and water when it begins to dry, especially in containers and warm, windy weather. In practice, water check daily in warm weather and every 2–3 days in cool weather; water according to soil moisture. Feel the upper 1–2 cm of soil and check below the leaf canopy; water when it is beginning to dry. Increase checks as days warm, but reduce frequency during cool or cloudy periods; dry soil plus heat encourages bolting.

Lettuce needs bright, indirect light for steady indoor growth.

Lettuce is toxic to cats and dogs. Keep out of reach of curious pets and choose pet-safe alternatives for accessible spots.

Propagate Lettuce from healthy stem or root divisions during active growth.

Use organically rich, moisture-retentive but well-drained soil. Lettuce performs best around pH 6.0–6.7. A good mix includes 60% quality potting mix or fertile loam, 25% finished compost, 15% perlite, fine bark, or coarse grit. Moist but freely drained; shallow roots need steady moisture without standing water.

Repot Lettuce usually not repotted after its final transplant; lettuce is a short-lived annual crop, ideally in the locally cool growing season, before persistent heat. Signs it needs a bigger pot: seedling roots fill or circle the starter cell, growth stalls between waterings, the plant has several true leaves and is ready for final spacing.
