Root-pruning would not be prudent.
The only time I root-prune is when I have a large plant in a large pot and the plant is significantly root-bound. If the pot size can't be increased, I might trim back all the top-growth by 1/3 and then trim roots. Since there is 1/3 less branches/leaves, these is less need for the mass of roots. I am simply trying to keep things in proportion.
