>>> I am always envious of gardens in wetter/cooler climates; the plants are huge compared to many of mine!
Wow do I know that feeling. Due to the dry summer heat in my climate, many of my roses are not quite as full and lush as those gardening in cooler areas. There are exceptions.
On the plus side, once the day temps are above 85F, I don't have any black spot because BS spores are not viable at temps above 85F.
