Because the temperature in my greenhouse can reach 140oF on a sunny summer day, most of my greenhouse plants spend the summer on my patio. Come fall, however, these plants must be moved back into the greenhouse. For them, it’s rather like returning to an indoor home after enjoying summer at the cooler, breezier beach. […]
