Rot on Paphiopedilum?

[Roberta]

The oldest growths on Paphs die back like that, so I don't think that there is a particular problem on that count (Others who do more with Paphs please jump in... ) The lack of roots (related to old, bad medium) is much more concerning. Repot for sure. Because they like to stay on the damp side, Paphs need repotting more frequently than most orchids, two years probably ideal, can be stretched if the bark is high quality. But better to err on the side of "more often". Paphs can be repotted any time. With luck, you'll get a new growth - and new roots. But the new roots may emerge a year or two after the growth, so don't panic if it seems nothing much is happening.

Without roots, you'll need to stabilize the plant after potting. I have found that two wood skewers, one on each side of the plant, works quite well, since there is really nothing on the plant itself that can be a good anchor point for a tie of any sort..

I know that it's normal for older leaves and older growths to turn brown. But that is exactly the problem! It's the latest growth that is browning. I do think i'ts rot because it's soft, not dried out.

See the growth that's starting to rot is the one with the current peduncle and flower.
