Hardy gloxinia

I wonder if I should do the same. A few of my tree peonies show some
chlorosis in the last two years. . However, most plants, including azaleas
do very well. I'm puzzled. And Lycoris have done especially well this year,
seed pods on al including squamigera (which may be balloons, even if they're
bigger than usual by different species).

Hi Adam:

I apply soil sulfur for the blueberry bushes in the same bed and yes,
the soils are alkaline. The soil pH ranges somewhere between 7.2 and 7.8
at Chicago Botanic Garden and the soils at my house were derived from
the same environmental factors - probably near the higher end of the
spectrum.

Rhododendrons, Vaccinium and other Ericaceceae plants all exhibit
typical iron chlorosis and foxtailing (magnesium deficiency) if no
effort is made to lower the pH.

Boyce? Why do you top-dress with powdered sulfur? Is your soil
alkaline?
