I love my asparagus fern, and have had it for many years. It's outside from spring to late summer. It has been having a harder and harder time being happy inside over winter the last few years. I kind of think that they are a little less opinionated when young. So when you put your ferns under shelter at the end of summer, is there any thing you need to do first. It's a good idea, that I and my vacuum cleaner will both appreciate.
