I had a cousin who had quite a green thumb. She always lots of plants, and a garden etc. When she had to move to a sr. community, she still had all types of plants jammed in her little flower bed. So, when she passed away a couple of years ago her daughter got a pot of onions she had growing. This summer she gave me a few onions. they are small onions, like you would buy in the grocery store as green onions. I have no idea what variety they are, and the daughters did not know. They just said that she had purchased them in the last few year as they were some like she had when she was growing up. Right now, they are doing well, they are in a big barrel. do these need to all be dug up? will they over winter if I put them in a big pot and take them inside? I don't know what to do since I never had onions at this stage, at this time of year.
