Its time to put some of our purchased Camellias into larger plots.

Would mixing half my garden soil (which i'm told is fairly neutral) and
half ericaceous compost be about right as a mix?

Also i have access to some rotted down pine needles below a big pine
tree and i understand this is fairly acidic.

Would there be any advantage in using the pine needle compost over the
purchased ericaceous compost of might it be too strong?

Thanks for any advice.
