Dino, welcome to the board, Im kinda new to the board also and alot farther south than you so not sure about you guys season in Minn, I would suppose it still may be early spring there and maybe your ginseng is just starting to grow there, It is true that ginseng, in its early stages 1-2 years will grow to its full height quickly, about 1 1/2 to 2 inches where i live for yearlings. Older plants will generally get bigger thru-out the season. Hope this helps
