Frequently Asked Questions

What pest or disease most commonly affects Lactuca sativa (lettuce) like ‘Olga’, and how can I control it?

Lettuce most often suffers from downy mildew (Peronospora) and powdery mildew, which show up as gray-purple fuzzy growth or pale powdery patches on leaves, especially when leaves stay wet. Remove and discard affected plants, improve airflow, and water at soil level (not onto the foliage). If problems persist, use an appropriate labeled fungicide for lettuce and mildew, applied per label directions.

During the 50-day growing period, how often should I water Lactuca sativa, and what soil moisture level should I maintain?

Keep soil consistently evenly moist for lettuce—don’t let it dry out between waterings, because Lactuca sativa quickly becomes bitter and can bolt. In active growth, aim for roughly 1–2 inches (2.5–5 cm) of water per week total, adjusting for heat and soil type, and water when the top 1 inch (2–3 cm) feels dry. Ensure good drainage so roots don’t sit in waterlogged soil.

How do I know when ‘Olga’ (Lactuca sativa) is ready to harvest?

Harvest at about 50 days from sowing when heads are firm and compact for the variety type, with outer leaves fully expanded and crisp. For best quality, pick in the morning and harvest before the center starts to loosen or stretch upward (early bolting). If you can squeeze the head and it feels tight, it’s ready; if it feels soft, wait a few days and recheck.

Silky, tender leaves unfurl with a cool, fresh crunch—Olga lettuce forms a lush rosette that feels almost velvet to the touch. Its flavor is delicately sweet with a bright, green snap, making it a standout for crisp salads and elegant garnishes. Grow Olga for dependable, 50-day maturity and a beautifully uniform head that stays attractive from garden to table.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 35°F before moving outdoors. Harden off for 6 days first.

Expert Note

Start lettuce for the cool stretch—aim to transplant when nights are reliably above the mid/high 30s and avoid heat to prevent bitterness and bolting.
