Magenta

Lettuce

50d to harvest

Velvety leaves unfurl in a vivid magenta blush, tender as spun silk and richly flavored with a pleasantly sweet, leafy snap. “Magenta” loose-leaf lettuce forms an airy rosette of frilled, softly ruffled foliage that stays crisp and bright through harvest, making it a standout for fresh salads and vibrant garnishes. Grow it for its striking color and delicate texture—an elegant, garden-to-table favorite at about 50 days.

Frequently Asked Questions

What pest or disease commonly affects Lactuca sativa (lettuce) like Magenta, and how can I manage it?

A very common issue is downy mildew (often showing as pale yellow patches on the upper leaves with fuzzy growth underneath). Improve airflow with wider spacing, water at the soil line (not on leaves), and remove badly infected leaves to slow spread. If it keeps recurring, rotate beds and avoid planting lettuce in the same spot for at least a season to reduce lingering disease spores.

How often should I water Magenta lettuce during the main growing phase?

During active leaf growth (roughly weeks 2–6), keep the soil evenly moist so it never fully dries out, aiming for about 1 inch of water per week in typical conditions. Water deeply early in the day, and adjust to weather so the top 1 inch of soil stays consistently damp—lettuce that dries then re-wets tends to bolt and becomes bitter.

How can I tell when Magenta lettuce is ready to harvest?

Harvest when leaves are fully sized for the 50-day target and feel crisp rather than floppy, typically once the rosette has reached a usable diameter. For best flavor, pick in the morning and cut leaves just above the crown; if you’re growing loose-leaf lettuce, you can do “cut-and-come-again” harvests by taking outer leaves first.
