Frequently Asked Questions

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.

Sowing Tips

Soil Temperature

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

Expert Note

For the sweetest, most crisp heads, keep lettuce cool and transplant into evenly moist soil before summer heat drives bitterness and bolting.
