I found a nice size Kimberly Queen at my grocery about a month ago but it was rather leggy. It was only a few dollors so I got it and put it in my plant stand by my door. I gave her one heck of a haircut when she got home. I also gave her a good boost with a ws fert and have been giving her a good soaking regularly. I also have top dressed with spent coffee grounds and frequently pour old coffee dilluted. She has doubled in size already!! Is this fern hardy enough to make it through a winter inside? Should I have repotted into a larger pot, she is still in the original 2 gal black plastic container she came in.
