Q.What’s Wrong With My Fern?

aSingularBee added on June 4, 2020 | Answered

I recently asked a question here 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 it’s usually around 50% humidity where I live. Even though the yellow leaves cleared up a lot, my fern still looks like it’s drying out! It doesn’t look too bad from afar and most of the fronds are alright, but closer up you can see dry greyish leaves and some black tips. I noticed that one of the fronds had dried up leaves that were completely curled into themselves. There are some scars that look like brown indents, but I’m not sure if that’s from my cat or something else. Most of the very young fiddleheads look like they’re doing fine. What’s going on here?

These will be the lasting effects of the powdery mildew. It would be good to prune off any infected tips, and keep treating until the growth come out unaffected. Treat the soil, as well, since spores will be there as well.

Other than this, the plant does look much better than on the last post. Just be sure to let the soil dry out a little, or remain only very slightly moist between waterings. Moist is good, wet is bad. Dry can be bad too, but its better too dry then too wet.
