The following was received via email: I live in Vancouver, in an apartment with electric heat. I have a small, protected balcony where my asparagus fern has happily hung all summer. I had intended to treat it as an annual and pitch it when the foul weather arrived, as I know bringing it in will simply result in all the tiny leaves turning brown and dropping all over the floor (and they are as resistant to a vacuum cleaner as christmas tree needles!). The plant has surprised me with its lush growth and if there is a way to overwinter it, I would like to do so. Can you advise me how to treat this plant to bring it through the winter?
