I made a comment in the " Rhododendrons and azaleas need a strong acidic soil" article.. I have had a long experience of loosin Rod., Azaleas, and Pieris as well

It looks that on inorganic acids are appropriate for these acid-loving plants. Can organic acids be safely and easily be used.? I am thinking of vinegar, for example, especially the apple vinegar one, which can have probably a lower pH, I believe.
