Yes, NutC, it had crossed my mind that the new shoots on my cuttings (ever hopeful!) mightn't conform to the original pattern of radial growth - I'll just have to wait and see - perhaps some may prove more 'bidable' than others??? & respond to careful re-pruning.
AlanB, the original bush was about 1 metre high in a fair-sized poly pot - it went into an oversized hole with a goodly supply of well-rotted manure beneath. That sort of cossetting would certainly aid recovery of your tree, plus the staking etc that others have advised. A generous mulch of compost in the spring would reduce moisture loss too. Best of luck!
