Been putting mums in garage at night. One in big container cover it up with big tarp.Not giving up with out a fight.
I was doing the same thing with my geraniums I finally gave up and brought them to the office to overwinter
Lug mums lug them out. I covered my things like that but today I am going to dig them out of their urns and put them in pot in the greenhouse. We figured that we have some plants, that others trash every year, for at least 3 and 4 years now. Barb in Pa.
Told Jerry wish I could put electric blanket on them at night. But will find them a place in garden. And mulch well.And hope they come back next year.
