Yellow leaves aren’t always a reason to panic, and can be a normal part of a plant’s life cycle. Unless brand new leaves are turning yellow or all the leaves change color at once, it’s likely just your plant retiring old leaves.

What other plant parents say
This plant was a pain in my butt at first but now Im beginning to love her but I’m not fully convinced lmao she was so bushy when I bought her and within a week or so she got dramatic and began crisping up, I just couldn’t keep her alive! I trimmed off her dead leaves and was left with maybe 4 fair sized leaves😅 now she’s sprouting leaves like nuts so keeping her soil drowned with water is working better than having good humidity and following watering recommendations😮💨
Bigleef Smalls has been a great addition to our family. I talk to him everyday. It’s strange, but it seems that he perks up when I talk to him. He gets a shower when it’s time for his feeding. He seems to enjoy that quite a bit. I really enjoy having him in my home.
So I put this plant outside at least a month ago to basically die - no watering and no care. Well it survived and I guess is okay with my northern exposure windows and balcony so I brought it inside watered and placed at my patio window for the rest of this autumn/winter season. I’m told ferns love bright maybe even direct sunlight but this Boston wants to live and is a trooper. Now let’s see if I can get some decent growth.
I have had this plant for two years. It is easy to care for. I have mine positioned in a south facing window. The leaves will brown from time to time, I tend to trim them off. It’s an attractive plant, I like how the fronds uncurl as they grow into new leaves.
