I am one of those persons who like the trees to face the same direction on my farm. Several weeks ago I was editing my farm and noticed something but couldn't remember what...there's a post here somewhere.
Anyhoo...it seems that if you erase your trees while in edit mode, when you place them back on the farm using the handy little paint tool, they'll all be facing one direction. At least this is my experience. I've tried it several times now and it works every time. It's especially handy for those pesky banana plants and orange and peach trees.
(hit send by accident before I was done)
This also works with the honey and other bushes.
Disclaimer: they may not face the direction you want them to initially. I've rotated the first one then used the paint tool and that seemed to work. Let's hope it continues.
It's a pretty good workaround - if you have a little time - until the trees come out in one direction when bought.
