My young Daphne tangutica is looking sad. I planted it about 2 months ago in a nice big planter box. It seems to be doing well until recently. The leaves are have brown spots and even the new leaves are kind of soft and slightly curled. Any idea what is happening to it? At first I thought it was the famous sudden death of daphne; however a closer look reveals several new buds. I wonder if it's bugs or fungus? Our winter raining season is starting.
