Yes, I tried the plugs a couple of years ago on another coop, probably Ella. They all lived and grew except only Tomato Soup overwintered. That said, I don't have any better success with large plants overwintering either. For a while, the plugs didn't make sense anymore when you can get large healthy plants for about the same price in the fall sales. But now, some plants have about doubled in price so I am trying plugs again this year. Also, a lot of the nurseries have cut back on the variety they use to offer. The plugs I got in May are starting to bloom.
