Germination & Seedling
2-3 weeksTiny cotyledons emerge within 7-14 days. Seedlings are delicate with thin stems and first true leaves appearing.
Keep soil consistently moist. Provide cool conditions (50-60°F ideal). Thin seedlings to proper spacing once first true leaves appear. Protect from harsh sun and wind.
Rosette Development
3-4 weeksPlant forms multiple rounded leaves in a tight rosette pattern. Leaves are soft, mild, and begin to thicken slightly.
Thin to final spacing if not done earlier. Maintain consistent moisture and cool temperatures. Mulch around plants to retain moisture and keep soil cool.
Vegetative Growth
2-3 weeksRosette expands with increasing leaf mass. Leaves become larger, more tender, and develop characteristic mild flavor.
Water regularly during dry spells. Remove any damaged or yellowing outer leaves. Monitor for pests, especially in fall. Reduce nitrogen feeding to avoid excess leaf production.
Maturity & Harvest Ready
1-2 weeks (can extend with proper storage in field)Full rosette is 4-6 inches across with tender, succulent leaves ready for cutting or pulling. Plant is ready for harvest.
Mâche maintains quality for extended period in cool weather. Can be harvested at full maturity or thinned/cut progressively. Keep moist for best texture.
Bolting (Cool Season)
1-2 weeks before plant deterioratesIn spring or if temperatures rise, plant may send up a central flowering stem with small white or pale flowers.
Once bolting begins, harvest immediately or leave if seeds are desired. Bolted leaves become bitter and tough. Remove bolted plants to make space for new sowings.

Harvest Tips
Harvest 50-70 days after sowing when rosettes are 4-6 inches across. Pick outer leaves individually for continuous harvest, or cut entire rosette at soil level with scissors. Best flavor in morning after cool night. For salad, harvest when tender and mild. Can be harvested progressively from 30 days onward (baby mâche). In regions with mild winters, fall sowings produce through winter.
Fun Facts
- 🌱 Mâche is called 'corn salad' because it historically grew as a weed among corn crops in European fields and was eventually cultivated as a valued crop.
- 🌱 The 'Piedmont' variety is a French heirloom from the Piedmont region, prized for its cold hardiness and ability to provide fresh greens throughout harsh winters.
- 🌱 Mâche requires no head formation and can be harvested leaf-by-leaf, making it more productive per plant than traditional lettuce over an extended harvest period.
