Regrow your lettuce and scallions. It really does work!
There are lots of food you can grow this way. If you put celery bottoms in an open jar with a little water, you will have celery. Green onions too. All those chives that are growing in the Alabama soil right now…pull them up & chop off the top, put the bottom in dirt & put the green part in your baked potato with sour cream…i’m hungry.
