I planted this for the first time this year - in Zone 5A. We have had a hot summer and so I have been watering this Bobo by sprinkler (I know, not ideal) overhead every day around 20 min. It receives morning shade and mostly afternoon sun. It is starting to show yellow leaves that keep falling, suggesting I am watering it too much. However, the flowers also show signs of sun-scorch (brown spots) so it has been very difficult to adjust watering time appropriately. I don't know if it is lacking iron, but I fertilized it early on when I had first planted it (May). Seems to be a fussy plant this year or maybe I am doing too many things wrong.
