Winterizing: Porcupine Grass
I planted porcupine grass in my deck boxes earlier this summer and they have really thrived- both in height and filling in. They provide great cover for my deck and I was wondering how I should protect it during the chicago winters.
Should I expect it to die back to the ground?
Do I need to wrap the first few feet (bubble wrap?) to give the grass structural support from the snow and wind?
Should I try to water it during the winter?
Thanks for any insight.
