What's wrong with my stag horn fern?

Asked March 29, 2020, 3:17 PM EDT

I have two French stag horn ferns in my house. They get the same amount of light, same amount of water, etc. But while one looks great (1st pic), the other has saggy fronds and is dropping fronds (2nd pic). There is no sign of infestation on either one. I use a hygrometer to test the soil, and water from the bottom when they are dry. Any suggestions on how to help my sickly stag horn?

I don't personally know a lot about growing a staghorn fern. I see that you have these planted in pots which seems to be a rather nontraditional method for these plants. In my research I found that they need a very fast draining medium. so I would start there. What is the medium you have them in? Even when mounting on boards, if using soil instead of peat moss I see that it is recommended a 1-1 blend of cactus and orchid bark medium. If you are using something other than this it may be too heavy. You did not mention anything about misting the leaves of your staghorn. I know that because these are tropical plants this is an important step in their care. I am attaching a couple of links for you to investigate more about your plants. After reading them you may determine some things that you can do differently for these plants. https://gardeningsolutions.ifas.ufl.edu/plants/ornamentals/staghorn-fern.html
