I’m having a ton of trouble with D Regia and I have absolutely no idea what is going wrong. I started it with two medium sized plants about a year ago and have propagated and killed several since then, I’ve tried growing them in a couple different spaces under different conditions and always run into the same problems. The first one I got was growing in a 5” deep pot, 50/50 peat/sand mix, originally from a greenhouse I had it growing in my highland terrarium right next to heliamphora, epiphitic urricularia, and highland nepenthes, all of which are very happy. Humidity 80+ with hourly misting system, temps upper 70s days and lower 60s at night, good airflow throughout the set up, top watered with RODI about once a week along with everything else, fertilized once a month with 25% strength maxsea. It did ok initially, but then started getting smaller and smaller, leaves were flopping over and turning black on the tips as soon as they unfurled, very little dew. After a couple months I repotted into the same mix with a deeper pot and took some root cuttings, it bounced back a few weeks later and started a second growth point, but after another month it looked just as bad as before.
I got another mature plant round then, figured maybe it was the constant misting that was bothering it and kept that one in a different grow space in the basement under bright t5s with some light from red/blue LEDs coming in from the side. 6 inch deep pot, this time with a highland nepenthes LFS/Pearlite/Orchid bark mix, watered weekly, fertilized occasionally with the maxsea, the room stays a little warmer, humidity in the 60s-70s, good airflow, no misting this time, growing along Mexican pings and very happy cephalotus. Same exact thing happened, leaves wouldn’t grow upright, tips turned black and it steadily reduced size. After a while I went away for 10 days and left it under a humidity dome standing in shallow water and came home to find the growth point killed off by mold. Took more cuttings, at this point I also had 5-6 small plants sprouting from the earlier cuttings and had them growing in small plastic condiments containers in sphagnum. I potted those up and they seemed to be doing well for a couple weeks in the same area in my basement, not much dew but they were growing fast and upright, then they started turning black at the tips and a couple died back, they look a little pale and aren’t as upright as before but I haven’t fertilized yet to see if that’s what’s causing all my problems. Now I have the second round of cuttings ready to be potted up and I desperately don’t want to waste them like I have the others. I have them in pretty ideal conditions from everything I’ve read, and I really don’t know what else to change up. Does anyone know what could be blamed for the browning tips and prostrate growth?
