Frequently Asked Questions

What pest or disease most often affects Lactuca sativa (leaf lettuce) like Crispino, and what should I do?

A common problem is downy mildew (especially in cool, damp conditions), which shows as pale yellow patches on leaf tops and fuzzy growth underneath. Remove and discard affected leaves, improve airflow between plants, and water at the base early in the day to keep foliage dry. If it’s spreading, switch to an appropriate labeled fungicide for lettuce/downy mildew and follow label timing at symptom onset.

How often should I water Crispino lettuce during its main growth phase, and how moist should the soil stay?

During the main growth phase, keep soil consistently evenly moist—aim for top 1–2 inches to stay lightly damp, not soggy. Water deeply about 1–2 times per week depending on heat and rainfall, then adjust so the soil never dries out completely; lettuce roots are shallow and will wilt quickly. Avoid frequent light sprinkling that leaves the root zone dry and keeps leaves wet.

How can I tell when Crispino (Lactuca sativa) is ready to harvest?

Harvest when plants reach the specified size and leaf texture is crisp and full, typically around 60 days from sowing. Check daily in the final week—lettuce can turn bitter and bolt as temperatures rise, so harvest promptly once the leaves are at your preferred size. For best quality, cut outer leaves first or harvest the whole head/rosette at crisp maturity rather than waiting for overgrowth.
