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

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.
