Germination
5-7 daysTiny seedlings emerge with cotyledons (seed leaves); first true leaves begin appearing
Keep soil consistently moist but not soggy. Maintain temperatures 60-70°F. Thin seedlings to reduce crowding.
Seedling & Early Growth
2-3 weeksFirst true leaves develop; seedlings establish 2-4 inches of growth with 3-4 leaves visible
Provide 12-14 hours of light daily. Water gently at soil level. Reduce crowding to improve air circulation.
Vegetative Development
2-3 weeksLeaves multiply rapidly; plant forms compact rosette with deeply crinkled foliage characteristic of Wonderland
Maintain consistent moisture and cool temperatures when possible. Apply balanced fertilizer every 2-3 weeks. Mulch to retain soil moisture.
Head Formation
1-2 weeksDense head develops with full, ruffled leaves; plant reaches near-harvest size with vibrant dark green color
Monitor for bolting signals (center leaves elongating, flower buds forming). Provide afternoon shade in heat. Keep soil moist.
Harvest Ready
Ongoing; productive for 2-4 weeks with continued harvestingPlant reaches full size (6-8 inches diameter) with tender, crisp leaves ready for picking
Harvest in morning for crispest leaves. Begin outer leaf harvesting or cut entire head. Water well before harvesting.

Harvest Tips
Begin harvesting outer leaves when plant reaches 4-6 inches (cut-and-come-again method) or wait for full head formation at 6-8 weeks. Harvest in early morning for maximum crispness and water content. Cut leaves 1 inch above soil level to encourage regrowth. Entire heads can be cut at soil level. Harvest before hot temperatures arrive to prevent bolting. Plant continues producing for several weeks with regular harvesting.
Fun Facts
- 🌱 Wonderland lettuce is named for its exceptional performance in challenging growing conditions, remaining productive in heat that would cause most lettuce varieties to bolt and turn bitter.
- 🌱 The deeply crinkled, ruffled leaf structure (called 'savoyed' leaves) not only provides visual appeal but also increases surface area for nutrient absorption and creates natural cups that hold dressing.
- 🌱 Lettuce has been cultivated for over 2,500 years, with ancient Egyptians reportedly using it as a symbol of fertility, while the Romans valued it as a calming food.
