So, originally I was worried that my staghorn wasn't growing any new fronds...and I was told that maybe I was underwatering it. I followed the whole water it often and soak it (I just couldn't bring myself to do it 2x's a day--so it was more like every 4 days). And now its leaves are falling off! Yellowing and browning from the center. Am I overwatering it? Is this something else? It's sort of near a vent so I just moved it. But it was fine before so it makes me think it's the water. Also, the leaves are not rotting, so I don't think that's what's going on below. Sad...because I really love this plant.
Also some background: it was next to a S window, but about 6 feet (diagonally--think triangle) from a vent. I've just moved it to an east window which has various objects between the window and the vent. If the vent was causing any problems, it won't any more. Though I'm inclined to think it wasn't the vent as it was doing well for the first 4 months or so in that location. I got it back in Oct.
