I have a beautiful kangaroo fern that is in distress and would appreciate any advice that people may have. The older growth develops almost translucent looking/bleached spots. Some of the leaves also have black spots and browning. There is new growth and it looks healthy to me. It's on a shelf about 6 feet away from a large window. It does get bright morning light, never direct light. Not sure if it's not getting enough light? I try to make sure it stays moist, but I also get afraid of overwatering. I live in Southern California and the air is dry, but I do use a humidifier in the room and try to keep it around 60% humidity. I think for about a week however I was running the humidifier too much and the humidity level was much higher. I have only had the plant for about a month and have not fertilized it since bringing it home. New growth seems to have slowed, but there are still new leaves sprouting. Any ideas on what may be going on? Thanks in advance for your help ♥️

Overall your Fern is quite healthy. If conditions are less than perfect, then some of the older leaves will discolor and gradually die back. To a limited extent that is inevitable. However, there are a few things you can do to limit the loss of older leaves.

It is too far off to the side of the window. It does want protection from the direct sun falling directly on it, but otherwise as much light as possible. Move it closer to the window or more in front of it.

Humidity is not an issue as long as you water it properly. As soon as the surface of the soil feels dry, water it thoroughly so some water trickles through the drain holes. Unless you water it multiple times per week, you need not be concerned about over watering it. Too much humidity is never a problem.

No need to fertilize your Fern more than 3 or 4 times per year and then only at half strength. Leaves that are unattractive can be cut off without harm to the plant.

I agree. Very nice plant! Kangaroo ferns aren't always easy to grow indoors and have it be that full!!

The smaller monstera on the floor, is that yellowish or is it just the photo? I'm wondering if that is getting too much light or something of that nature. I lived in southern CA at one point, and sometimes the apartments can act as a greenhouse for plants- good and bad. For example, my monstera is not in front of a window, it's just at the edge of the frame where it gets later day sunlight- and I'm up north.

Thank you both for your help! I have moved the fern slightly and hope I can keep it healthy.

Missy Sue - yes, that plant is a goner I believe. I propagated a cutting from a larger mother plant and it never looked healthy/did well. Thank you for the tip about the light. I'm originally from the Midwest, so still getting used to this California sun.

Oh. I learned how to do that, it can't be a leaf by itself. For monstera, you need a section of the large stem, with at least two leaves coming off the stem. Lay the stem firmly in constantly moist potting mix, then keep it warm and give it light. Roots will grow into the potting mix, but it takes a bit.

What are the bumps on the leaves of my kangaroo fern?

Hi hardersjunk, to the site!

The bumps you are seeing on the fronds of your : Kangaroo Paw Fern (Lecanopteris pustulata subsp. pustulata) may be spores forming. I no longer grow this fern but here are two of my photos in our database showing leaves and spores:
