Just found this thread! as a local again I'm blown it exists :D
I'm only recent back to brisvegas after being up north for nearly 4 years and my established garden had to be gut wrenchingly left behind. So many people up there now with my morengas, hbwr, woolemis (yes survive up there), aristolochias and a whole lot of oddball herbs. Anyway would be keen to keep up the green thumb. Would anyone be keen on a kombucha mushroom? It's not quiet gardening but its still a living thing XD.
Years ago, I dumped a heap of acacia longifolias around my suburb green ways but it seems none :'| survived.
