Kwiek

Lettuce

45d to harvest

Sunlit, tender leaves unfurl in a loose rosette with a crisp, water-bright snap and a pleasantly mild, sweet-green flavor—never bitter, even as the season warms. Kwiek’s foliage stays supple and clean-looking, making it a joy to gather for fresh salads and vibrant garnishes, as well as for quick tosses into greens-forward dishes and silky sauces. At about 45 days from sowing, it delivers an eager, garden-to-table harvest with an elegant, leafy presence.

Frequently Asked Questions

What pest or disease most commonly affects Lactuca sativa (lettuce/“Kwiek”), and what should I do if I see it?

A common issue is downy mildew (often shown as pale yellow patches on leaf tops with grayish growth underneath). Improve airflow by spacing plants and watering the soil (not the leaves), then remove badly infected leaves right away to stop spread. If it keeps worsening, use a label-appropriate fungicide for lettuce and follow the spray schedule carefully.

During the main growing phase, how often should I water Lactuca sativa, and what soil moisture level is best?

Keep the root zone evenly moist—aim for consistently damp soil, not soggy—especially from about week 2 until harvest (roughly days 15–45). Water deeply when the top 1 inch of soil starts to dry, which is often every 2–4 days depending on your heat and soil; lettuce stress from drying out can trigger bitterness and bolting. Mulch lightly to reduce quick drying, but ensure the bed drains well.

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

Harvest when heads/rosettes reach their expected size and the outer leaves feel firm and fully expanded; for Kwiek plan on about 45 days from sowing. Lettuce is best before it bolts—check daily for a tightening center or flowering stem, and harvest immediately if you see it starting. Cut at the base early in the morning for crisp leaves and minimal wilting.
