Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout in 5-10 days under cool, moist conditions. Tiny seedlings emerge with cotyledons (seed leaves) followed by the first true leaves.

Keep soil consistently moist but not waterlogged. Provide bright light; thin seedlings to proper spacing once they have 2-3 true leaves. Protect from direct intense heat.

2

Vegetative Growth

3-4 weeks

Plant develops multiple leaves and establishes a rosette shape. Leaves become progressively larger and more ruffled with the characteristic red-tinged edges appearing.

Maintain consistent watering and regular feeding every 2-3 weeks with diluted liquid fertilizer or compost tea. Thin to final spacing if needed. Monitor for early pest damage.

3

Full Leaf Development

1-2 weeks

Plant reaches mature size with full rosette of crispy, ruffled leaves. Red coloration intensifies; leaves are tender and at peak flavor.

Continue consistent watering and maintain cool temperatures if possible. Begin harvesting outer leaves for cut-and-come-again harvesting. Watch for bolting in warm weather.

4

Harvest-Ready to Bolting

Variable; extends 1-3 weeks with proper cool conditions

Lettuce is at peak harvest quality. If temperatures rise or day length increases significantly, plant may begin to send up a central flower stem, causing leaves to become bitter.

Harvest immediately when ready. Provide shade cloth in hot climates to extend harvest window. Once bolting begins, plant quality declines rapidly and should be removed.

Common Pests

  • Spray with strong water stream; use insecticidal soap; introduce ladybugs; neem oil as last resort

  • and

    Hand-pick in early morning; create barriers with crushed eggshells or diatomaceous earth; beer traps; encourage predatory beetles

  • Crop rotation; resistant varieties; remove infested plants immediately; reflective mulch as deterrent

  • Remove affected leaves; row covers to prevent infestation; spinosad spray if severe

  • Yellow sticky traps; strong water spray; neem oil; encourage natural predators

Harvest Tips

Begin harvesting outer leaves once plant is 4-6 inches tall using cut-and-come-again method; harvest in the morning when leaves are crisp and full of moisture. For full-head harvest, cut at soil level. Rominette reaches best quality in cool weather (50-70°F); harvest before temperatures consistently exceed 75°F to avoid bitterness. Plant bolts quickly in heat and long daylight, so succession plant every 2-3 weeks for continuous harvest.

Fun Facts

  • 🌱 Rominette was developed in France and combines the tenderness of loose-leaf varieties with the crispness preferred by commercial growers and consumers.
  • 🌱 The red coloration in Rominette leaves increases when exposed to cooler temperatures and UV light, a natural stress response that actually enhances appearance and may increase antioxidant content.
  • 🌱 Lettuce is one of the oldest cultivated vegetables, with evidence of cultivation dating back to ancient Egypt, and modern crispy varieties like Rominette are relatively recent developments from 20th-century breeding programs.
