Cockleshell Prosthechea indoor care/watering

[itzi]

I've posted before about my "mystery" Prosthechea, which I bought as a fragrans, but may be mislabeled. According to the AOS page for the genus, the "cockleshell" variety, which mine will fall under regardless of exact species, prefers moist but not soggy media year-round. But, visiting other pages, I've seen conflicting information, ranging from keeping them nearly constantly dry during winter, to frequent watering with rapid drying.

I grow mine indoors, where the humidity is around 35%-50%, near a shaded west window with supplemental lighting. I've been watering every 3-4 days by showering it in my sink and then letting it soak for about 10 minutes.

Is this right for my conditions? Have any of you grown these types with success in similar conditions? I'd appreciate any advice as two of the new little growths on the sides of the largest pbulb have started browning and I'm worried I'm watering wrong. I know I'm probably overreacting as I've hardly had this plant for a month, but if I'm doing anything blatantly wrong I'd rather correct it asap.

Thanks ^_^

Mounted or potted? If potted, what medium? New growths turning brown on most Cattleya alliance plants indicates not enough watering. My observation has been Prosthecheas with new growth should not be allowed to become dry. They are different from Cattleya hybrids in this.

In your conditions, if it's potted, I would probably be watering this kind of plant in active growth every 1-2 days. I wouldn't try to grow it mounted in a house. I couldn't water such a mount enough.

Yes it is potted in a mix of mostly orchiata bark with some leca. I'll probably just water it every morning then! I just worry since theres a bit of roots exposed at the surface which always dries out very quickly, but I hope the core of the pot will at least take 24 hours to dry out. I'll soak it right now and check tommorow morning how it looks.

Sorry, this is not an expert answer, but I bought mine (if it's even the same as yours ) in early August because I'd read it would do well in my orchidarium. I mounted mine and it stays at 80%+ humidity and is watered daily. It dries out between waterings. It seems happy so far with lots of new root growth and several new leaves as well.

You don't want your plant in Orchiata and LECA to dry out completely when it's pushing new growth.
