should euphorbia mellifera be cut back in autumn?
By Jendick
France 
Fairly exposed position, full sun. Survived very cold snaps and frost last winter & is multiplying of own accord. Flowered profusely from early spring into May. We cut off dead flower stalks at base in June. In mid-Oct, new growth is coming on strongly below mature leaf stalks. Should we cut back the mature growth now. Our autumn thus far has been unusually mild.

I have two of these in my front garden Jendick and i don't ever prune mine (except to deadhead).
I would say unless you want to control the shape or size just leave it alone.
