Germination
7-10 daysTiny seedlings emerge with cotyledons (seed leaves). Seeds germinate in 7-10 days at 60-70°F.
Keep soil consistently moist but not soggy. Provide indirect light. Thin seedlings to proper spacing once true leaves appear.
Seedling to Early Vegetative
2-3 weeksTrue leaves develop; plant shows characteristic red coloring on leaf edges. Height reaches 2-4 inches with 4-6 true leaves.
Maintain consistent moisture and cool temperatures (60-70°F). Remove weaker seedlings. Begin indirect light exposure.
Vegetative Growth
2-3 weeksLeaves expand rapidly with deeper red pigmentation. Plants develop their distinctive frilly, lobed leaf texture. Reaches 6-10 inches tall.
Water regularly; mulch to retain moisture and cool soil. Thin to final spacing if needed. Monitor for pests. Provide afternoon shade in summer.
Maturity/Harvest Ready
Harvest window lasts 2-4 weeksFull-sized rosette with 12-16 inches diameter. Leaves are deeply lobed, frilly, and richly colored in burgundy-red. Compact, dense head ready for harvest.
Begin leaf harvesting when leaves reach full size. Use cut-and-come-again method for prolonged harvest. Cool nighttime temperatures enhance color and flavor.
Senescence/Bolting
Varies with temperature; accelerates above 75°FPlant sends up a flowering stalk as temperatures warm. Leaves become bitter and tougher in texture.
Harvest immediately before bolting occurs. Provide shade and consistent moisture to delay bolting. Remove plant once quality declines.

Harvest Tips
Begin harvesting outer leaves when they reach 4-6 inches long, using the cut-and-come-again method for continuous production over 2-4 weeks. Alternatively, harvest the entire head by cutting 1 inch above soil level when fully mature. Harvest in early morning when leaves are crisp and hydrated. French Red is most tender and flavorful when grown in cool conditions (60-70°F); heat causes bitterness and bolting.
Fun Facts
- 🌱 French Red lettuce gets its distinctive burgundy pigmentation from anthocyanins, the same compounds that give blueberries and red grapes their color, and these pigments actually increase when the plant is exposed to cool temperatures and bright light.
- 🌱 Lettuce is one of the oldest cultivated vegetables, with evidence of cultivation dating back to ancient Egypt around 2,680 BCE, and red leaf varieties like French Red became popular in European gardens during the Renaissance.
- 🌱 French Red lettuce is extremely cold-hardy and can tolerate light frosts (down to 28°F/-2°C), making it one of the best choices for fall gardens and early spring harvests when many other greens have bolted.
