In November, 2011, I ordered four Pecan Trees from TyTy Nursery that were supposed to 8-9 foot tall. They told me that they would ship in December while they were dorment.
I received them in January and planted them right away (forgetting that they were supposed to be bigger than the 5' +/- trees that I got).
So far only two of the four have showed some signs of life (but not much). I haven't contacted company yet, but based on the these reviews I don't think it is going to do any good; but I plan to.
