I'm not sure there is much difference between the two sediment materials per definitions, Stone. Both basically calcium carbonate in variant forms. But the quantities layered in the soil here compared to Gause may vary. That's the only thing I can make of the difference in the Beautyberries there and here. Mine here in the city struggle with drought and the limestone. Down there, they suffer the same drought periods as we do, pretty much, yet those Beautyberries look so much greener and healthier. Danged if I can figure it out.
I do hope now that I bought a 12# bag of acid-loving fertilizer that just arrived this week, I can dose my azaleas, gardenias and now, my American beautiberries as well, more often and have healthier plants all 'round.
