Overwintering pennesetum setaceum???
I'm new to OG's, but love how they look. I have two pennesetum setaceum rubrum in gallon containers. This OG is for Zone 9, not 5-6 where I live. I plan to bring them in the house when it starts to get below 40 degrees. Should I cut them back now and put them in a cool place or should I leave them tall in a window until next spring? Thanks for any suggestions.
