Dark spots on cattleya leaves
 
Hi!

I have some very dark spots on a hybrid (L. purpurata werkhauseri x C. whitei coerulea). The plant have just arrived (today) from Germany, wrapped in paper for 1 week in extreme weather (around 37 C during the day). The vendor is a serious one, they work with Floralia in Brazil. I don't want to accuse them of something they can't control (like summer heat...)

Could this spots be the result of the hot weather or lack of air? Can I treated somehow?

The dark area is not mushy, but I really don't know what it is...

The other plant I bought from the same vendor, L. Purpurata werkhauseri (ardosia x ardosia flamea), in the same parcel, looks better, but also have spots. Not so dark and they are different.

Please, a little help! Thank you very much!!!!

Hi Nico
I'm not positive, but to me the last two pix at least look like burned foliage (I have lots of experience with burned foliage unfortunately).
I don't really know about the others - I'm sure more people will chime in

looks like damage from extreme heat during shipping....they will probably recover.....one of the challenges and hazards of shipping this time of year.....gl

I agree with the others about the spots , and you have pretty cockatiels. I have 2 ,did raise them several years ago .

I feel so much better now... :)
I haven't see a lot of burned foliage on my catts, because I keep them indoors (this year I put them on my balcony for the first time). I wasn't sure about the last two pics, but sun/heat burn it was my first guess.

I'll keep my eye on them and hope for a soon recovery. At least for L. Purpurata. :pray:

Thanks a lot!

My cockatiels are pretty and very smart, Gin, but they are savage :evil: Only the chicks (4 until now) have been tamed and now they are happy to live with a friend of mine. :)
