Do You Fertilize Ferns?

Question

I have southern shield and autumn ferns…I’ve heard that you don’t fertilize any ferns… is that so, or are there some you do feed and some you don’t?

Answer 1

In general, you shouldn't need to fertilize them if you provide rich, organic soil for them to thrive. But it does depend on the fern. Some benefit from a monthly application of a natural fertilizer like fish emulsion. I'm including a University of Georgia publication with an extensive list of ferns and their care:
