Frequently Asked Questions

What pest or disease most commonly affects Lactuca sativa (lettuce), and what should I do if I see it?

In Lactuca sativa, downy mildew and leaf spots often show up in cool, damp conditions, and slugs also commonly damage tender leaves. Remove and discard infected leaves immediately, improve airflow by spacing plants, and avoid wetting foliage when watering; if mildew persists, use a labeled fungicide suitable for leafy vegetables. For slugs, hand-pick at dusk and use a physical barrier (like copper tape or diatomaceous earth) around beds to protect the bases of plants.

How often should I water Lactuca sativa during the main growing phase?

During the main growth period (from about 2 weeks after transplanting to harvest), keep the soil consistently evenly moist, not waterlogged. Water about 1–2 times per week depending on heat, aiming for roughly 1 inch (2.5 cm) of water each time, and check moisture by pressing a finger into the soil 1 inch down—if it’s dry, water. Avoid frequent light sprinkles; lettuce roots prefer deeper, steady moisture to prevent bitter leaves and stress.

How do I tell when Lactuca sativa ‘ready to harvest’ at around 45 days?

Harvest when leaves are fully sized for a loose-leaf head, with crisp texture and good color; most loose lettuces are ready around 45 days after sowing or transplanting depending on conditions. Start harvesting outer leaves when they’re large enough to eat, or cut the whole plant at the base once the rosette is well developed. If plants start sending up a flowering stalk (bolting) or leaves turn noticeably more bitter, harvest immediately.
