Wisteria Tree Leaning
I have a beautiful wisteria tree. It is pruned into a beautiful umbrella shape. My problem is in its early years it was allowed to lean. So can I cut roots on the opposite side and try to start slowly pulling it back in an upright shape? Also, I call it a tree because it stands alone in the yard and has a trunk at the bottom, 3 or 4 inches in diameter. I have another wisteria on a trellis as a vine. Also, we bought this property some 5 years ago and the plantings were already here.

You can cut the roots some, but you do not need to. To correct the lean, tie a rope around the "tree" trunk and anchor it in the direction you wish the tree to go. Use a piece of garden hose over the rope where it touches the tree to protect the plant. Tighten the rope a little every few weeks to pull it back into the right angle. This will correct it without hurting the tree.
