So every year I get my ferns out early on the patio, some little bird decides to nest in one of them. One year I didn't discover it until it was too late and she'd already laid eggs. We had cute baby birds, but my fern was messy and kind of died off on that one side. Does anyone else have this problem? Have you found a way to prevent it? So far, I just try to keep a lookout and take the fern down if I spot a bird flying in and out of it. Not a very good solution.
