How to fertilize Blackstem Spleenwort

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Blackstem Spleenwort after it doubles in size or once a year—whichever comes first.

This is my first birds nest fern what is the most important things I need to know ? I love him. #BirdsNestFern

My poor fern is struggling. Recently the new fronds in the crown have been black, and now there is very little new growth. There are some tiny bugs in the crown, too, but I don't know what they are. Can she be saved?? #BirdsNestFern #help

Looks Dull Any idea what’s going on with my Hurricane Fern? I moved it to my sunroom since it didn’t seem to love the AC blowing on it but now it looks dull and crispy. It’s not crazy hot in here and it only gets 1-2 hours of direct sun.
-
My Birds Nest fern isn’t happy I have moved it out of direct sun, as suggested by the app (it wasn’t getting a lot to begin with), but it’s definitely declining. Leaves are darkening and yellowing a bit, and definitely droopy. I know very little about plants and hate to be harming this one.

Hi everyone! My first ever post on greg,i brought her in March this year and put her with my other plants so she has humidity, how is she doing? (This is my first ever plant of this kind) #BirdsNestFern

New to this behemoth. It is droopy and crispy underneath. We just had a few weeks of heat. It sits outside on a covered porch. How can I help ut bounce back? #BlackSpleenwort

First wall mount! I transferred my birds nest fern from a pot into a sphagnum moss/wall mount situation. I think it came out pretty well and it looks great on the wall! Hopefully watering it for the first time in a week or so doesn't ruin everything....

Just rescued-What does she need? I picked up this bird's nest fern from Lowe's today. She was on clearance. She has wet soil and I notice some yellow bottom leaves and some brown tips up top. Any recommendations on how to get her healthy? (I know to let the soil dry out. What else?)
-
She sits about 3 ft from the window…why does her leaves look like this???

My #BirdsNestFern is in a decline. I haven’t done a repot in a while, I was using Alaskan Fish Fertilizer mixed into her water but stopped that recently and I water as needed with water dosed with Super Thrive. HELP!?! What is the problem and what can I do? I can’t kill another plant that my husband picked out and bought for me all on his own :’(

🧐 Troubleshooting
When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.
Inspect the soil moisture; too dry or too wet soil can cause problems.
Ensure the plant is getting the right amount of light, as too much or too little can stress it.
