I have twelve potted hydrangeas, but this year, i was not able to enjoy their blooms, i know i'm doing something that is not right.
recently, i have noticed this brown spots on their leaves
and finally, when they bloom, it was almost a size of a 10 peso coin...
i decided to transplant them, and this is what i saw... they are root-bound... poor hydrangeas, there isn't enough room for them to grow
