Thanks to my home's previous owner and neighbor having fences in the wrong places, I now have to move 24 sq ft of my 12 ft long garden. This includes well established (I've owned the house for 8 years and they were here when I bought it) poppies, peonies, and naked ladies (a. k. a. Surprise Lilies) I understand that I may not be able to save the plants for blooming this season, but hope to save them for future seasons. I have been trying to dig 18" deep with the Poppies to get as much root as possible. . . I have A LOT of these to dig out and only just started so ANY advice will be GREATLY appreciated!!! ALSO! I found something that I'm confused about. What I found in the middle of where I'm pulling these plants from is a root about 2" dia. close to the top of the soil with small green leaves or leaf-like growths covering the top of it. . . it is VERY sturdy, but NOT like a tree. . . it also goes deeper than the 18" I've been digging. . . Any ideas???
