Rescue in need of help?

Hey guys, newbi here. Both to the forum and to Orchids in general.

I recently rescued this Phal(I think) from my grandfather's backyard. It has been neglected for several years. It had some mild root rot that I took care of with some research and a good repotting. I was so excited when I noticed its sad little spike had started to grow, and quickly! but now, it seems to have some brown/black stuff. There was a spot on the leaf that I assumed was sunburn, but now I noticed there is more, possibly spreading. It is possible that I didn't notice/realize what i was looking for before delving into researching orchids more. I'd rather not loose this plant, as it belonged to my grandmother, who passed several years back. If I'd known this poor lil thing was in the yard, I would have saved it sooner!

I'm not sure if this might be crown rot or possibly an infection. Any suggestions would be welcome. I have pulled this plant away from my others and quarantined it in the kitchen. The plant has 5 leaves, two seem to be infected/burnt/icky. Should I trim them off? I won't be doing anything but research till I get some feedback from you guys. Thanks in advance.

It looks like you have a serious case of stem rot. If the rot isn't stopped it will kill your plant.

Pour peroxide or alcohol over the black area to see if you can stop the rot from progressing, repeat several days in a row. I am a firm believer in keeping as many leaves as possible to help feed the plant but some cut them off.

Good luck - Brooke

Thanks brooke! I did as you suggested, w/ peroxide, and a large amount of the black came off one of the leaves, showing just a small amount of actual damage to the leaf. I assume its safe to leave the peroxide on to dry, as it dries faster than water and will be continuing to put air into the rot as it does dry?

I don't mind loosing the one leaf, if need be, but I'm with you on keeping them at all possible, even if they are disfigured at the end of it all

The problem is not the leaf, I want to stop the rot on the main stem. I want the leaf to stay attached as long as possible but if the rot infects the stem it will migrate up into the crown and kill the plant. Stem rot is the same as crown rot except it starts lower.

Repeat the peroxide treatment a couple of times and hope the issue was halted.

I'm wondering, Brooke. Would a dip in Physan help as well? I think if it were mine, I'd want to unpot it and see what else is going on below the surface. Thanks for the tip on the Peroxide, though. Works wonders on a lot of things. Just not sure if Physan might be overkill or might fight with the peroxide.

Oh, Welcome to Orchid Geeks, Chaos!!

...another one bites the dust...

I usually recommend the peroxide because almost everyone has it in their house or can pick it up rather easily. Using Physan is just as good but harder to find. You can also use alcohol on the plant.

Is it too early to tell if its working? Should I expect it to continue to dry up like the one spot? Or is 'less black and icky' good enough? Thanks again guys! I'm hopeful!

From my understanding stem rot spreads very fast. I have personally had experience with crown rot and it is dead in a few days. So if it hasn't gotten worse that is a great sign. I also currently have a phal that has some dried rot on the stem from a previous infection that is stopped. I am very carful when watering to not get water drops there.
