Rot on Paphiopedilum?

Beautiful leaf pattern on your paph!

Thanks! It would be so disappointing if I would loose it.

Well, nowadays because of Corona, I do spend a lot more time at home than before. So balcony doors and windows are open a lot more than usual. Yeah except when we sleep. But then we have these small narrow windows on top of the regular windows, those are open almost all the time. So yeah there should be fresh air in the house.

Normally too the humidity is not very high here, in fact more dry I would say around 40%.

The only thing that I can think of is maybe water got trapped between the leaves and I didn't look well enough. But it's more likely that I let it dry out a bit too much between watering rather than over watering.

I have however repotted it now, it was the last bit of bark that I had, mostly small bark, and I mixed it with some spaghnum moss and perlite. I think this way it won't dry out as fast, it was in just bark and nothing else.

I had to cut off the entire growth, so now it's only got one growth left (the oldest one) oh and I sprayed it with hydrogen peroxide 3%. I'm going to put some cinnamon on there now.

By the way I do have a problem with mealybugs on my 3 newest orchids, but I don't see any of that on this one. Besides they haven't bean anywhere near this orchid. The other 3 have been separate from all my other plants since I bought them. Unfortunately I think they came with the mealybugs.

That's a real possibility too. Having water trapped between leaves near the stem region could possibly create some kind of effect.

I haven't checked yet, but I'm expecting that cells of leaves need enough oxygen to survive too, just like roots. So maybe water trapped between the leaf regions pressed against the stem (ie. water between leaf and stem .... or leaf against leaf at the stem region) could lead to oxygen starvation or rotting, or unwanted things growing. Maybe in some growing areas, air-movement, nice growing temperature and other conditions helps with avoiding that kind of thing - as in water staying and/or stagnating in certain spots.

Little animals like mealybugs could bring unwanted organisms too maybe - apart from themselves - as in stuck on their bodies. If no mealybugs were seen on the first orchid, then just focus on growing conditions.

Even though my outdoor orchids get bombed by water each early morning ----- all my under-balcony orchids never get their leaves wet - except for cases when it's super rainy and super windy - where rain blows onto the leaves. But nice to report that wind plus rain combination with my orchids potted in airy-enough media has never resulted in health issues. But outside of those kinds of conditions, I just keep the leaves (which includes crown too - as that's leaf area as well) dry.

Anyway - keep us posted! Looking forward to hear of good news later!
