LIkewise, here. I took wildgrown up on their 10lbs of 2YO roots last fall, and they have done great. Wish I'd gotten 20 pounds... that has to be the motto of sang farmers in the spring: I wish I had planted more. Of course, transplaing that many roots (over 1000) took a while... and the dry fall followed by a quick freeze left me with maybe a 2 week window to get 'em all transplanted, after sitting in the fridge almost a month due to the drought. Considering that impediment, I'm delighted with the results.
So far, it's about evenly divided between 2 and 3 prong, and one four prong. Varying degrees of size, some small, some huge. Some deformed leaves, but the plants don't seem to be decaying. Some in the last round of planting are taking their sweet time coming up, I'm still finding a few new ones.
Quite a contrast from last year when I put out 100 3YO roots in the spring, and three came up.
