Frequently Asked Questions

What pest or disease most often affects Lactuca sativa (iceberg-type lettuce) and how do I manage it?

Look for aphids and slugs/snails on iceberg lettuce, especially in warm, humid stretches. Spray aphids off with a strong stream of water and use insecticidal soap if they persist, and hand-pick slugs at dusk or set beer traps/diatomaceous barrier around plants. Also watch for downy mildew and botrytis (gray mold) in cool, damp weather—improve airflow by spacing heads properly and water at the soil line, not the leaves.

How often should I water Lactuca sativa during the main growing phase (from transplanting until head set)?

Keep the soil evenly moist but not waterlogged while the plants are forming leaves and tightening into heads—typically about 1 inch (2.5 cm) of water per week, adjusted for heat and wind. Water deeply 1–2 times per week rather than daily misting, and aim for consistently damp soil 1–2 inches down. If the soil swings from dry to wet, iceberg lettuce is more likely to become bitter and develop loose or poorly formed heads.

How can I tell when Lactuca sativa (iceberg-type) is ready to harvest?

Harvest when the head is firm and the leaves are tightly packed, usually around 70–80 days after sowing (about 75 days to maturity for your crop). Check by gently pressing the outside of the head—if it feels springy or loose, wait a few more days. Harvest in the morning when heads are coolest to reduce leaf wilting and maximize crispness.

Crisp as fresh-cut snow, Saharan delivers a dense crisphead with a cool, clean crunch and a gently sweet, green flavor. Its tightly layered leaves form a satisfying, spoonable texture—sturdy enough to hold its bite while staying tender at the core. Grow Saharan for standout salads and elegant platters, or for refreshing wraps and bright, leafy garnishes that stay crisp through serving.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 35°F before moving outdoors. Harden off for 6 days first.

Expert Note

For heat-tolerant crisphead types like this, keep soil evenly moist and transplant only when nights are reliably cool-to-mild to reduce bolting risk.
