Does Flora(l) abuse exist?

Or, do you think that it exists?
Manipulating plants to grow a certain direction, slowing down or speeding up a plants’ growth?
Pruning hedges or Bonsais?
(Probably) plants and flowers and trees don’t have souls, so that could be a reason for some to trim away unconcerned.
But do plants feel pain (or is their metabolism changed when we cut their branches)?
You personally, do you feel bothered when you knot a tree?
When you see juices come from a wounded branch, does it remind you of a bloody flesh wound?
