This is an Acer campestre (hedge maple) that I grew in the ground for a few years to thicken. It developed 2 major roots that then divided. There is actually a little space under the trunk as you can see in the detail picture. Any comments on how to handle this?
A. Leave it as a feature and accentuate it during future repots.
B. Root graft seedlings (I have them) to give a more traditionally spread nebari
C. Insert a rock with carving to fit to provide a reason for the roots splitting to either side.
