Q.What’s Wrong With My Fern?
I’ve asked a question here before about my Kimberly Queen Fern; it had a case of powdery mildew which is now being treated organically. I no longer mist it as often because the humidity where I live is usually around 50%. The yellow leaves have cleared up after clipping them, but my fern still looks like it’s drying up on the edges! It doesn’t look too bad from afar, but close up you can see either black or dry and grey/brown leaves, and some yellowing fronds. I noticed one frond that had leaves which were curling into themselves. What’s going on here?

You will, still, need to treat the soil with a fungicide, as well. None of the old or dead growth will recover, but new growth should come out clean when treatment is working.
If this is still happening with the new growth, then keep treating with fungicide until no new instances occur.
Here are some articles on fungicide use:
