I've planted these "All Americans" 160 days ago on Oct 26 in a 2 year old established 10" raised bed. It's been a very harsh winter, as far as North Texas is concerned. The foliage is beautiful, but when I feel the tops, they are only about 1" in diameter. I dug 1 up and it was extremely long(about 12"). Should I leave them in or dig'em up?
