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.
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.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 40°F for reliable germination and early growth.

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.
