2018 Transplanting My First Tree Peony

P. Rockii Lavender Tree Peony Bud
It was past time to move the first tree peony that I'd like to watch. That peony, a very vigorous pink-lavender P. Rockii peony is featured as the first peony in my recent 2018 Southern Peony Seedlings article. I've never moved a tree peony before, so I wasn't quite sure what to expect. I've always heard that tree peonies don't like to be moved. However I'm hoping this one won't be hurt since it is still a young plant and not fully established in its original location. I was a bit surprised to see that this tree peony still had some green leaves, as almost all of my other tree peonies have already died back. The first thing I did before I tried to dig it was create a planting hole for it. I also added a bit of EcoScraps fertilizer in the hole. I never fertilized the P. rockii tree peony seeds when I planted them. So I'm curious to see what this peony can do with some extra food and more sun. I decided to plant it in a nice, sunny spot right next to my bird feeder.

I tried to be very careful when digging it out, especially since it was very crowded (and I mean very) in original location. I put the original seeds in my peony seedling bed about 2-3 inches apart when I originally planted them. (I know, I know - that is too close, but I wasn't even sure if they would sprout or not since I'd previously not had much luck growing tree peonies from seed.) It's a wonder these tree peonies are able to grow at all, much less bloom with that much competition. However this particularly vigorous seedling was the tallest of all its siblings, and it had pretty much figured out how to beat the system. It had sent out a very long lateral root that was actually taller than the plant itself. The root was growing past all of the other sibling tree peonies out of the peony seedling bed. I tried to get all of it out, but it looks like I still lost a bit of the root at the tip.

The root actually ended up being even longer than the tree peony was tall. The root (what I got of it) was 30" long! So that means it would have been even longer if I hadn't snapped the end off. The tallest stem was 28.5" tall. I'm curious to see how tall this tree peony grows with time. Since the hole I dug for the root was not 3 feet wide (or larger), I decided to dig a trench for the long lateral root next to my planting hole. Maybe that's not the best solution, but that's what I decided to do. I don't really have the time or energy to dig a hole that big anyway! I am really, really excited to see what this tree peony can do next year. I also planted a newly purchased tree peony 'Leda' that I just decided to purchase this fall from Song Sparrow near it. It won the APS Gold Medal in 2014, but I never bought it until now. I am curious to see how these two tree peonies compare as they grow...
