This past spring, I got really aggravated with two of my TPs that were 2 to 3 years old. The herbaceous roots are obvious when they occur. But I waited patiently to differentiate the two. When it was obviously a herbaceous root sprouting, in April, I dug up both TPs, rinsed the roots off with water, and used a saw to cut the majority of the herbaceous root off in one piece. Then replanted the TP and replanted the herbaceous root. Both TP and herbaceous roots survived and bloomed this spring. I guess I am just lucky.
