Q.Potting Muscari indoors then overwintering the pot in an unheated garage until Spring
I received 10 muscari bulbs (free) from a Vendor recently, and since there is a considerable amount of snowfall already (November 1 in Edmonton, Alberta, Canada) outdoors, namely where I would have planted the bulbs in September/October, I am attempting to start them indoors in a pot. I plan to allow for root development over 2 weeks indoors and then put the pot in my (unheated) garage, where I know the pot will not freeze through as it would if I placed it outdoors. I plan to house the pot in my garage until Spring, when I will place it outdoors. I’d appreciate any feedback about my plan. Thank you. Catherine Nemeth knemeth@shaw.ca

Yes, you can pot up the plants for some early spring enjoyment!
