"The leaves and needles will be the pH of the soil that the roots are in.
Hence some will be acidic and some will be basic."

What?  Is this true?  Because in the south, where you see pine trees you can 
pretty well guess the soil is acid.  In fact, in The South, I think if you 
see a forest, it's on acid soil.  The only places where the soil isn't 
acidic is where humans have hauled in ground lime.  Or river and creek 
bottoms, where gravelly stuff has washed and settled.  Upland, it's all 
acidic.    Donna
