Anyone try to regrow romaine lettuce? You tube has a video showing how it’s done with romaine, carrots, celery and onions. Simply cut about 2” from the bottom of the romaine stalk, place it in 1/2 inch of water (which is changed daily) and it will start to sprout within a few weeks. I am now going to transplant it in the garden as a test.
Yep although the few I have tried that way never seem to take and die off. I don't notice much of a root system before transplanting but maybe I'm doing it wrong.
