Re: Pruning philadelphus (mock orange)

I don't know what the official line on this is, but I cut some rogue branches off mine yesterday. If it is quite small, and all growing how you want, I'm sure you could leave it alone. If it is huge already, it might be worth lopping off some of the bits that are likely to get in the way. My normal routine for shrubs like this (once solidly established) is to take out one third of the stems to the ground, and take a third off the top of another third of the stems and leave the rest alone.
