I have a SuperTreat septic system which waters my garden. Some plants
thrive, others don't. I'm wondering if this could be due to
phosphorous in dishwashing and laundry detergents?

Which plants do which?
I used water from laundry to water fruit trees one year when we had a long
dry spell. Killed two mature persimmon trees. I was told by a bloke from the
dpi that phosphorous from the washing powder would do that.
