Geranium overwintering

Zone V5C 3H6 | vicarious1 added on October 26, 2017 | Answered

Hello I am planning on the upside down overwintering of my Geraniums. When they hang can they stay in the dark. Our garage is very cold so I want to hang them in a Styrofoam box in our basement. The same way I keep our Dalhia bulbs. But its not very pretty so I want to know can the box be closed only with aeration holes around? Thank you Vic Vancouver BC Canada

Styrofoam doesn't breathe so it sounds like perfect breeding for fungus. Read the following article. It mentions the need to water your plant, making fungal problems more likely.
