Again, I think you missed my point on planting depth. If the case I will
repeat with this address for proper planting depth. The tree should be
planted at the depth the roots are coming off the trunk. Any deeper and
they are too deep. Just prepare your planting site to the depth you would
like to plant. Any deeper and adding fill will more or less sink and the
trees will be planted too deep. Do not fertilize or prune until the second
growing season. Proper mulching would be a good idea which I suggest as
well. Please see proper mulching. Also if you properly prepare a planting
site and not just dig a hole you may have to stake if your trees will blow
over in a mild wind. For the most part I do not deal with products or
promote them. However, it has been rightfully suggest not to use wire in a
hose and use broad belt-like flexible material that will allow the tree to
sway. No body would make them for me so I make my own. We sell the as
well. The are called CAMB GUARDS. Please do not use wire in a hose. No
matter how big the hose the pressure is still localized. I tell you these
things because I care for you and the trees. If you decide you would like
to stake and use CAMB GUARDS I will make you a good deal.
