Large holes in pseudobulb
Default Large holes in pseudobulb

Hello, this is my first time posting and very new to growing orchids and really plants in general. This one I've had for about 1 1/2 years and not sure what kind it is. I went by the "one ice cube a week" rule of thumb and almost killed it. I researched and found out that rule isn't the greatest and learned some basic orchid care tips. I re-potted it, and started watering and fertilizing regularly and it got better. I was not sure if I should cut off the old spikes? Anway, I decided to put it in the wooden hanging planter outside and new growth quickly started but now there are some holes in a pseudobulb and a couple of leaves with holes. I brought it back inside and put cinnamon paste in the holes. I'm not sure if it's bugs, fungus or virus. I tried a castile soap recipe from online and also physan 20 but seems to be worsening and there are some small dimples starting on other leaves. I would hate to lose it since it was my first orchid. Any help would be greatly appreciated.

Welcome to the Orchid Board!

This appears to be a Dendrobium. There are many different kinds from different climates. Did it have a name tag?

I can't see enough detail to see the damage to the pseudobulbs. What are your ambient temperatures and humidity? Approximately where do you live? Dens generally can't take full hot sun. Viruses don't cause holes.

The person that gave it to me said they got it from a friend that grows them and that it wasn't a species that is sold in supermarkets, that is the only info I received. I live in Florida so it's pretty humid, around 70%. It's been in the 80's for a few weeks and before that mid to low 90's. I had it hanging under a pergola on my back porch, which faces West so it got afternoon sunlight but pretty much indirectly.

I couldn’t be certain, but based on the look of it, it really looks like a Den. nobile hybrid (similar to the kind you’d get from Yamamoto orchids).

Unfortunately, I can’t see the holes in the photos. I think we might need a close up of them.

Unless the old canes are specifically rotting, I wouldn’t cut them off.

Here is another picture, it was a bit of a challenge to get one with enough detail that was also a small enough file size to attach.
I checked around in the media for bugs and fungus but looks good and no funky smell

Let's hope it is not a rodent issue!

Looks like something has been chewing on it. A friend here on OB grows outside in Florida and has a lot of issues with curly tail lizards or iguana. Could it be that?

I've never noticed either of those species of lizard here. I'm in Central Florida and see mostly house geckos and anoles. That would be kind of nice if it was a lizard, I'd know my orchid would be safe from further damage for now since I've got it inside. I'm not positive I believe the holes aren't getting any bigger now. The area looks a bit dried out from the cinnmon, alcohol and what not that I used to treat it.

Whether lizard or insect, etc, it definitely looks like mechanical damage of some sort. I've not seen a fungus, bacteria, or virus that looked like that. Then again, I'm no botanist.

I totally agree... I'm not a botanist either, but that looks munched.
