Frequently Asked Questions

What pests or diseases commonly hit Lactuca sativa (lettuce) and how can I prevent and treat them?

Watch for aphids and slugs/snails on tender lettuce leaves; they often appear as distorted growth, holes, or sticky residue. Rinse aphids off with a strong stream of water and use insecticidal soap if colonies persist, while hand-picking slugs at dusk and setting beer traps or copper barriers protects young plants. Keep foliage dry with morning watering and spaced plants to reduce downy mildew risk, which shows as yellow patches on top with fuzzy growth underneath.

How do I tell when Flashy Butter Oak lettuce (Lactuca sativa) is ready to harvest?

Harvest when heads are firm (for romaine-type habit) or when leaf clusters are full and reach the typical size for your bed—usually around 50 days from sowing. For the best texture, pick leaves when they’re crisp and tender, before the plant bolts; signs include rapid stem elongation and leaf bitterness. Use scissors to cut outer leaves first (letting the center continue) or harvest the whole plant once it’s fully developed.
