I've tried several varieties, soils, in the ground, out of the ground, lots of water, less water, lots of sun, shade, and everything else I can think of. My petunias always start turning brown, drying out, and dieing. What can I do?
I am in austin texas and it is about 90 degrees here. I read that they like the sun and could tolerate heat.
I just recently read about dead heading and started that. Could that be the reason they die? Do they die after too many flowers?
