How to Propagate Romaine Lettuce
Lactuca sativa
| Methods | Water, seed |
| Difficulty | Beginner |
| Best season | Spring & fall |
| Time to root | 1–2 weeks |
| Group | Outdoor / garden |
Another popular kitchen-scrap regrow, though with a similar honest caveat to celery: water regrowth gives a decent second harvest of small leaves, but transplanting to soil is needed for a full new head.
Water propagation
- Cut off the base of a lettuce head, keeping about 2 inches.
- Stand it in a shallow dish of water, cut side up.
- Set in a sunny spot; change water every couple of days.
New leaves sprout from the center within days to a week.
When to propagate
Spring and fall for best outdoor growth; can be started indoors any time.
Common problems
The base rotted. Change water frequently and keep only the bottom submerged.
Questions people ask
Can I get a full head of lettuce this way? Rarely from water alone — transplant to soil after initial regrowth for a fuller result.
