Grey water on Natives - yes

 Use the Planet Ark or Aware brand.  Check them out in your Supermarket.
These have been tested on the Proteacea species.  They are made from plant
oils etc, and are pretty good cleaners.

 

doesn't Don Burke recommend being very careful using greywater on Aussie
native plants? Something about phosphorous?

we are using "aware" atm, they address this by not using any phosphates or
petrochemicals. you'd probably find i think, most brands have been reducing
their phosphates for years but "aware" claims not to contain any "chemical
phosphates" at all.

and if my terrible maths can be relied upon, it seems to be really good
value for money, too. :-) lastly, i've been pleased with its performance -
the last lot of whatever-brand-it-was i was using was just crap.

our washing machine pumps directly out onto the garden... i need to make the
hose longer so i can water more stuff with it as the water is proving not to
be killing anything, but that's my problem - i'll get to it. ;-)

I did a greywater workshop with Ross Mars, and he showed us
a table listing various brands and the correspondign phosphate
and salt levels. He pointed out that the liquid detergents all had
low salt levels, so that is a useful rule of thumb.

 I doubt that Planet Ark would increase salt levels to destroy the
environment.
Most natives, eg Proteacea group, that it has been tested on would not
tolerate increased salt.
