Rhododendrons and blueberries seem to have essentially the same
nutrient requirements, hence any results of research with
blueberries will be of great interest to the rhododendron fan. A
report given at the recent meetings of the American Society for
Horticultural Science at Stanford University indicated that
blueberries were unfavorably affected if the nutrient medium
were high in either calcium or phosphorus. So, if our
rhododendrons aren't thriving we might suspect too high pH, too
much nitrate or not enough ammonium, too much calcium or too
much phosphorus. Progress is being made and any research such as
this brings us a step nearer to being able to efficiently
correct unfavorable conditions. Writing in the June 1957, issue
of the Journal of the Royal Horticultural Society, Mr. E. H. M.
Cox has this to say about his recent visit to the northwest. "In
Portland we were much impressed by the new Experimental Garden
of the Rhododendron Society of America. This lies on two
peninsulas in a lake. Apart from its
