Q.transplanting
I have a potato bush tree that I want to transplant. Any tips for a healthy transplant?

May, June and July is a good time to move the Potato Bush, they are still fairly dormant and the sap is very slow.
Mark the direction that your shrub is facing, so that you situate it in the new planting location the same way.
Dig as much of the root ball as possible and move the tree to the new planting hole quickly.
Water well in the first 2 weeks, then taper off.
