What can you grow from veggies bought at the store?
I have sweet potatoes growing in my garden this year (saved from the ones that I planted last year, which were in turn purchased from the produce counter at the local store), and got to wondering, what else could be planted and harvested from supermarket produce? I know about garlic and non sweet potatoes, but can you grow anything else like that? Celery perhaps, or onions? And how would you do it?
