Brown Spot Eating Through Phalaenopsis Leaf
Default Brown Spot Eating Through Phalaenopsis Leaf

I just noticed a huge deformity in one of the leaves of my phalaenopsis orchid. It's like something just ate through the center of the leaf. It's a huge brown crevice-like spot and it's dryer than the rest of the leaf. Kind of looks like sunburn, or maybe some kind of bacterial/fungal rot? I've seen this before in pictures, but I can't remember what it's called. I think it's pretty common. Please can anyone tell me what this is and how to fix it? Pictures are attached. Luckily, the rest of the orchid looks just fine.

I don't know what it is... but I would keep a very close eye on it and if it spreads at all cut the leaf off ensuring the remove all the affected area.

Use a sterile blade and dab the cut leaf with cinnamon to avoid any infection in the cut.

It may be sun-burn in which case it won't spread but if it spreads it's either fungal or bacterial and needs removing before it affects the rest of the plant.

Brown Spot Eating Through Phalaenopsis Leaf Male

I had a spot very similar to this on one of mine. I have to agree that you should keep a close eye on it. My phal almost died because I didn't realize what was going on - I just thought it was sunburned as well. The good news is that my phal is still alive a year later, struggling, but appears to be pulling through.
