Frequently Asked Questions

What pest or disease commonly affects Lactuca sativa (leaf lettuce) and how do I treat it?

Watch for lettuce aphids and slugs/snails, which are common in cool, moist lettuce beds and can chew leaves or leave sticky residue. Rinse aphids off with a strong jet of water and remove heavily infested leaves; for slugs, hand-pick at dusk and set copper tape or bait stations labeled for slugs in edible gardens. Also check for downy mildew (yellow-green patches with fuzzy growth underneath leaves) and remove affected leaves early to improve airflow around plants.

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

Keep the root zone evenly moist from transplanting through head/leaf expansion, aiming for soil that stays damp 1–2 inches down but never waterlogged. In most home gardens, this usually means watering about 2–3 times per week during mild weather, increasing to more frequent watering during warm spells. Mulch lightly to reduce surface drying so the plants don’t get stress that triggers bitterness or premature bolting.
