Steeltrap thank you / and congrats on finding some big roots as well.
Answer to question 1 - You know I had never thought on that,but now that you asked I can not remember finding a realy old root that would still have the shape of a man,,a emperors root,,sure cant,,I do not no why that is..Chieftian may be able to answer that question..
2 - If I was going to transplant some big roots I would wait untill the sap went back down into the main root myself after the stalk is about gone.Also I would dig around the root widely,,,so to speak,,,and create a rootball,sorta like when they transplant a tree from a nursery,,,and then replant the whole ball with the root in it back around the home etc,where you want to place it,main thing,make sure to dig a big clump
I have never had one to die doing it this way.I to love to look at them.
