I have a Euphorbia grandicornis (Cow's horn) that is extremely root bound. It belonged to my father and I know that it was in the current pot for at least 4 years. I am attempting to re-pot and I am not exactly sure what the best method is. Trim the roots and re-pot all or cut away from main stem that looks dead and re-pot? (I am most bothered but what to do with all of the roots??)

Thanks for any help!

Hard to get rid of all those roots. Am I correct in the assumption that those roots are mainly attached to the 'dead' main stem?

I am sure these will re-root if you start with the arm cuttings, but it would take time for new root systems to develop which means the arms would sit idle and/or deteriorate...

My approach would be to repot with the roots and see if there is a way of minimizing the appearance of the dead looking main trunk by shortening it to just above the highest alive branch...
It is what it is!

The main stem on these plants sometimes dies back, but the low-down branches will persist... this feature is especially evident in seedlings, where the main stem basically terminates when it branches early on close to ground level. I agree with Thijs' advice. You can restart the arms from cuttings but you may see the same thing happen afterwards to them. This is not a small plant in the ground and it tends to require some space in containers after a few years. I have never tried to trim the roots.
