My cattleya pseudobulbs are turning purple...

[Erin410s]

Hello OB!

I just noticed my cattleya turning purple on the pseudobulbs. I started researching why this may happen and got freaked out that it may be a fungal infection and to get rid of the plant before it spreads to the rest of my plants. This orchid is very special to me and I don't want to get rid of it. The leaves and pseudobulbs feel firm. Please help me discover what this is!!!

Another picture of the purple you are referring to would be helpful. to me I just see pigmentation from high light exposure. Often orchids get some purple to them if they are in the higher end of their required light exposure.

From the one photo the plant looks a bit dehydrated and lanky. Are the roots good? This has nothing to do with the purple, just wondering.

I also agree it's high light exposure. Not necessarily a bad thing; I like my plants to show a little bronzing and I've had good results. Too much, though, and it will start to burn so watch out!

I got this orchid on a clearance rack after an orchid show had been in town. It barely had roots and leaves looked horrible. It has been watered more frequently now that the temperature/sun is hotter. My cats got ahold of few of the leaves roughly a year ago, thus causing permanent damage.

To me the purple looks like it is due to light exposure, and that is not a bad thing as long as nothing burns.

I think the purple you are concerned about is related to Fusarium wilt. I see no indications of that disease here. You can find out more about Fusarium wilt at Orchid Pests, Orchid Diseases

I'll toss in a little unsolicited advice - I recommend that the next time you repot, consider either a terracotta pot, a plastic net pot, or a lot more inert drainage material (styrofoam, etc) int the bottom of the pot if you must stay with clear plastic. These potting options will help facilitate root drying in between watering - something Cattleya alliance plants really need to keep the roots from rotting.

I would agree. I see white roots with green root tips all of the way to the bottom of the pot-always a good sign.

I see healthy roots too and that is good. But I would recommend maybe slightly more open chunky medium when you re-pot. Best not to re-pot till new roots are just started growing.

Purple in the plant is healthy and the roots look healthy. Keep it up.

Look fine to me. I have some that do this. I put all my Catts when I re-pot into terra cotta pots. Also so a tip on uploading more photos is that I have to upload between every picture. I just hit browse pick my picture upload it the go back hit browse again and so forth. Until you have all the pictures you want then hit post or what ever it says.
