I would try to bonsai it.  I wrapped a piece of plastic coated, copper 
wire around the whip from the ground up.  I then promptly forgot about

According to the rabbits that I hired to scar the trunks of my fruit 
tree, scarring induces early fruiting which will slow growth rate.  The 
scarring inhibits the flow of carbohydrates to the roots.  Many authors 
list high Carbohydrate/Nitrogen ratio as one of the things that tips 
maturing buds into fruiting mode.  In time, the effects of the scarring 
will be overcome by the tree and it will resume a more normal growth 
pattern. Then it is time to hire more rabbits.

I think scarring predisposes the trunks to internal rot.  Also, it is 
difficult to enforce quality control with the local strain of rabbits.  
They tend to be much too thorough.
