Quick Facts:
- Days to harvest: about 50 (often sooner for baby leaves)
- Hardiness: Cool-season, handles light frost
- Light needs: Full sun to part shade
- Water needs: Moderate (consistent moisture keeps the hearts sweet)
Planting:
- Direct sow or transplant.
- Depth: 1/8 in
- Spacing: 10–12 in for mini heads.
- Timing: plant in cool windows. Little Gem is more heat-tolerant than some lettuces, but it still bolts faster once it heats up.
Care:
- Watering: keep it steady. If it dries out, you’ll see bitterness and tip burn sooner.
- Pests: slugs love the tender inner leaves.
- Heat: afternoon shade buys you time.
- Optional move: if you want tighter “mini romaine hearts,” let it size up before harvesting the whole plant.
Harvest:
- Whole heads: harvest when it feels firm in the center and is palm-sized.
- Or harvest outer leaves first if you want a longer harvest window.
- Storage: rinse and dry well, then refrigerate with a paper towel.
