Frequently Asked Questions
What pest or disease most commonly affects Lactuca sativa (leaf lettuce), and what should I do first?
Watch for downy mildew and aphids, which commonly hit cool-season Lactuca sativa, especially when leaves stay wet. Remove and discard infected leaves early, space plants so air can circulate, and water at the soil line in the morning to keep foliage dry. If aphids appear, rinse them off with a strong stream of water and apply an insecticidal soap directly to the undersides of leaves.
How often should I water Lactuca sativa during its main growing phase (around weeks 3–8)?
Keep the soil consistently evenly moist but not soggy; aim for about 1 inch (2.5 cm) of water per week total, adjusted for rainfall and your soil’s drainage. Water when the top 1 inch of soil feels dry, because lettuce quickly develops bitter flavor and bolting if it dries out. In warm periods, split watering into two shorter sessions to maintain steady moisture without waterlogging.
How can I tell when Lactuca sativa is ready to harvest at ~60 days?
Begin harvesting leaf lettuce when outer leaves are full-size and feel crisp, usually around 60 days from sowing/transplanting depending on conditions. For head types, harvest when the head is firm and leaves are mature; for leaf types, you can use “cut-and-come-again” by taking outer leaves while leaving the center to regrow. Avoid waiting too long past maturity, since overmature plants are more likely to bolt and turn bitter.
