Frequently Asked Questions

What pest or disease issue is most common on Lactuca sativa, and how do I treat it?

On lettuce (Lactuca sativa), aphids and fungal leaf spots are common, especially in warm, humid weather and when plants stay wet. Spray aphids off with a strong water jet, then use insecticidal soap if needed; remove and discard leaves with spotted, spreading lesions and improve airflow between plants. Avoid wetting the foliage during evening watering and water at the base to reduce leaf-spot spread.

How often should I water Lactuca sativa during peak growth to keep it from bolting?

During the main growth phase (roughly weeks 3–6 for most heads/lettuce types), keep the soil consistently evenly moist, not soggy. Water about 1–2 times per week to soak the root zone, then adjust based on heat—target the top 1 inch of soil staying moist. If the soil dries out repeatedly, Lactuca sativa can stress and bolt; mulching helps stabilize moisture.

How can I tell when Lactuca sativa ‘Little Leprechaun’ is ready to harvest?

Harvest at about 50 days from sowing when the rosettes are firm and well-filled, with leaves that hold together when gently squeezed. For best texture, pick in the morning before heat triggers faster growth and bitterness. If leaves start elongating rapidly or the center forms too quickly, harvest immediately to avoid a tougher, more bitter result.
