disturbing a newly planted redbud
I just planted this redbud four to five weeks ago. I would really like to disturb it by repositioning the upward line of the trunk by an inch. The esthetics of this are not appreciated by the single photo and discussion of the position is not the point here but the photo does show the size of the trunk. The tree is an arching 6 feet tall. I would have do dig around the root ball enough to lift it up to slightly change the tilt. This is my question: Is it best to do this in Autumn after leaves have dropped, mid Winter, or late Winter soon before Spring reawakening....or it is very ill advised to disturb it all all?
