What's wrong with these geraniums?
Last year I planted a few different kinds of geraniums. Some in the ground , some in pots. They all did great until a couple of weeks ago. regardless of the location and the soil condition their leaves started to curl upwards almost like shrinking.With or without watering didn't make a difference. They eventually stopped flowering. I pulled out the curled leaves but even the new ones came out curled and stayed very small.I can't see any insects or mites on them.
I used to think geraniums were easy to grow but now I'm puzzled. Does anyone have any ideas?
