Staghorn woes
Hi everyone,
Posted on plantclinic a while ago because I had no idea this sub existed. Wasn't able to get much advice over there and figured you guys are probably a wealth of information and could help set me on the right track with my fern.
I've had this for a few years now, and while it's never thrived under my care (I expect a combination of poor lighting conditions and infrequent fertilizer), it's never had fronds that have died from the base like this before. This is the second consecutive time it's done this, where it finally gives some new growth only to turn yellow, then brown, then black at the base. They usually fall off shortly after this. What's more worrisome to me is that it's now happening to one of the few large fronds it has, and I fear this is the beginning of the end for one of my favorite plants since I suspect that big frond is going to fall off too and the fern won't have enough surface area left to get the energy it needs to survive in these conditions. Or, it's got root rot, which is even worse.
Last two photos are from about a month ago, when I first asked for advice and she was a bit healthier... I'd love to figure out what's going on and save her, I'm quite fond of this plant.
Notes:
- I suspect I'm overwatering it. I usually leave it until the medium is a bit crunchy, and then soak it in the shower until it's heavy and dripping (usually one good spray for a few minutes, come back and spray it again for about 30 seconds for a good soak) and leave it hanging in the shower to drip the excess. The medium holds a lot of water, more than I remember it holding. It gets a shower about once per week (not on a schedule, just depends on if the medium goes crunchy or not). It used to be that I underwatered it and fronds would die that way, so this is probably overcompensation.
- I realize that the lighting situation is not ideal. It's a little ways from the window, and was growing lopsided (I have no where else it can hang to get "even" lighting), so tried to compensate by adding a grow light to the other side. One of my recent attempts to make it happier was to "filter" the light through a little frosted plastic bag to avoid a direct lighting situation, but if that's not good enough I am open to suggestions.
- It used to have more antler fronds (and wasn't so lopsided), but as far as I am aware, it never had an obvious shield frond. It was purchased that way.
- The temperature and humidity level are kept fairly consistent. It's usually slightly on the humid side and ranges between 21-24c in the house on average. The air vents in the ceiling nearby are kept sealed to prevent cold or hot air from blowing all over the plants. That being said, sometimes I do throw the window open to let fresh air in at night for up to 6 hours at a time, and that can get as cool as 14c or so.
Thank you in advance for any advice you're able to provide!
