is ericaceaus compost used for other plants other than stated

Not really no! Presuming you mean Azalea, Rhododendrun and Camilla's? Can you not take it back where you got it and ask for swap?

Nope - you only use for plants needing an acidic compost, take back and get a different compost!

Phew, thanks Moon grower!

Hey lass you know your stuff - don't fret!

Or better still, go buy some acid loving plants. Yay! That's the best plan. :-)
