Hi, Just wondered if anyone could help me please. I have inherited a garden with some lovely old plants and have identified most of them. I have identified one as a Pittosporum which is now quite large about 4 ft wide x 8 ft tall and I thought was an evergreen. It flowers in the summer with little purple flowers with a honey scent. However after looking at it today it appears to be shedding all of its leaves, (it did it last year too but not quite so many). I was going to prune it back a little but now unsure really of what to do with it as I don't want to kill it. Any advice would be most helpful I would add I have only lived in this house for 2 years so the Pittosporum is quite new to me.
