Thank you Cynthia, but I don't have a green house. Is it still a cause for concern ? My orchids grow outside, so I get all kinds of unwanted weeds in my orchid pots, one in particular is most annoying , the clover..or whatever you call it. It's everywhere , and I have to pick them off my plants everyday !!! I haven't had problems with the fern yet, but I've only had my orchids outside for less than a year. Hope the fern will just sit there and look pretty and not send out too much spores. Thanks for the tips , I'll watch out for little baby ferns..
