Frequently Asked Questions

What pest or disease most often affects Lactuca sativa (leaf lettuce), and how can I control it?

Leaf lettuce (Lactuca sativa) commonly suffers from downy mildew and aphid outbreaks, especially in cool, damp weather. Improve airflow and water at soil level, then remove badly affected leaves; if aphids appear, spray the undersides with a strong jet of water and use insecticidal soap only if needed. Keep beds weed-free because weeds host aphids and mildew spores.

How often should I water Lactuca sativa during the main growing phase (around weeks 3–6)?

During the main growth period, keep the root zone evenly moist—typically about 1 inch (2.5 cm) of water per week, split into smaller soakings if it’s hot or windy. Lettuce signals stress quickly: if leaves start to feel dry or get bitter/tight, increase watering frequency while avoiding soggy soil that promotes mildew. Aim for consistently damp soil, not waterlogged ground.

How do I tell when Lactuca sativa is ready to harvest at about 60 days?

Harvest when leaves reach the size you want: for loose-leaf types, you can start picking outer leaves as soon as plants form a usable rosette, usually well before 60 days. For full heads (if you’re growing heading types), wait until the head feels firm when gently squeezed; if it feels loose or starts stretching upward, it’s likely approaching bolting and should be harvested immediately. Morning harvesting gives the crispest leaves.
