which vegetables can be regrown?
Cabbage, lettuce, and bok choy can all be regrown from scraps, meaning you can always have salads and delicious Japanese/Chinese meals! Don't throw out the leaves you trimmed off the head, but instead place them in a bowl with less than an inch of water.
Set your dish in a windowsill and wait for the carrot tops to regrow which make a nice addition to salads or use as a decorative garnish. Celery. Cut off the base of the celery and place it in a bowl of water with the stalk tips facing up. Be sure your water only covers the bottom of your celery, not the entire bulb.
