Phrag. Sedenii browning leaves and media level
A couple questions here...
I bought the plant back in October. I didn't think much when a leaf on the lowest (oldest, I think) fan started dying in December because it already looked a bit sad from the start. However, in the last two or three weeks two other leaves have started browning, one on the same fan as the first and one on the middle fan. The third fan, which has been actively growing, seems OK so far. Is this natural senescence or might it be a cultural problem?
The plant is indoors with indirect sunlight and supplemental artificial light, 65-76° F, 55-70% RH (usually low 60%s), it gets flushed with distilled or sometimes tap water every 3-4 days and I spray the surface with distilled on the off days to keep it moist. It gets fertilized once per month with a 20-10-20 fertilizer at 66 ppm N. Media is small bark and coarse perlite.
My second question is about the level of the medium. The current level is as it was when I bought it, but the bottom of the actively growing fan sits well above the surface. The pot has sufficient room for me to fill it in and just cover it, but I'm not sure if that would bury the older fans too deep. Any thoughts?
