Why have my cattleya leaves turned red?

[bhawk3]

Can you tell me why some of my Cattleya leaves have turned red after repotting. I didn't used a lot fertilizer.
Do you have to clean the dried sheaths from the stalks.
Thanks

After repotting you want to put the plant in a shaded area for a week or two. They are putting energy into growing new roots and cannot handle as much sunlight for awhile. Try moving them to a more shaded location for abit.

Wow quickly did this happen after repotting? Does the plant appear healthy otherwise? Wilted? I think we need additional information before any conclusions.

And no, you do not need to remove dry sheaths from the pseudobulbs.

You don't have to remove the dry sheaths, but it does offer bugs or pest a place to hide and cause issues. I always remove the dried sheaths, but I only have 25 plants. I know people who have much larger collections. They only do this once or twice a year. Have Fun,Rich

A picture would help to give you advise. Which of your Cattleyas are getting this change of colors?

[Halloamey]

I agree with everyone, a picture would be helpful, but I think it is the case as Connie suggests follow her advice and everything should be fine.

A pic might change my response, but most the time red in plants is due to them making higher levels of anthocyanins, a class of pigments like chlorophyll or xanthins (yellows). The red absorbs light particularly well and basically acts as self-made sunscreen -- this is why the young leaves of lots of plants are often red. It's a sign the plant is getting a lot of light and may be sensitive to it, and so you may want to give it more shade, but in itself isn't a bad thing. I grow under a grow light in my living room and most my new shoots go through a phase of being pretty red or purplish til they age and firm up.
