"Rhododendrons, for example, are often thought of as acid-loving. In
reality, they love magnesium, which is sometimes more available at a low
pH, and they aren’t particularly fond of calcium. They’ll grow just fine in
a high pH soil if they have sufficient magnesium and lots of organic
matter. I’ve seen huge blueberry harvests on high pH soils."

Is this true?
