I have four grafted trees planted in my yard and three seedlings of Mahachanok planted out as well. I would describe the growth habit of my trees as medium to perhaps just under medium....but definitely not Pickering-esque. On a 10 point scale, if 10 were the fastest growing and 1 was the slowest, I would put the Maha growth rate at about a 4. The seedlings, by the way seem to display similar vigor and growth habit.
