Frequently Asked Questions
What pest or disease most commonly affects Lactuca sativa (green deer tongue), and how can I manage it?
Lettuce commonly gets downy mildew (often showing pale yellow patches on leaves with a gray-purple growth on the underside). Improve airflow and avoid wetting the foliage, then remove badly infected leaves to slow spread. If you see early symptoms, treat plants promptly with a labeled downy-mildew fungicide and keep spacing so the plant canopy dries quickly after watering.
How often should I water Lactuca sativa during the main growing phase?
Keep the soil evenly moist from first true leaves until harvest—lettuce roots stay shallow, so let the top ~1/2 inch dry slightly but don’t allow the bed to fully dry out. In warm weather, this usually means watering about every 2–3 days, increasing frequency if the surface dries faster. Consistent moisture prevents bitter flavor and helps reduce bolting risk.
How do I know when green deer tongue lettuce is ready to harvest?
Harvest when the heads/rosettes are well-formed and leaves feel tender rather than tough, typically around 45 days from sowing. Check for a full-size rosette and leaf color appropriate for the variety; if leaves are still small, wait a few days. For best texture, harvest in the cool of morning and pick before the plant shows tall center growth (early bolting).
