I planted several petunias. It’s October and they’re dying. Do I pull them out of the ground and start over next year, or can I
trim them and leave them for next year? I've always thought they are annuals but I've heard otherwise. It gets cold here, with a n occasional snow. Seattle area

Petunias are annuals. They can take a light frost but will not withstand continued cold or frosts. You can start fresh next spring or try to overwinter them indoors.
