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).
