New leaves dying on cattleya

[sperpich]

Hi,
I have a cattleya and the new leaves keep dying. The leaves have been dying for a while so I repotted it into a bigger container about a month ago. It does have some new roots starting. I water/fertilize once a week for 3 weeks and then flush with water the 4th week. It's in a east facing window. Just wondering what is going on and how to fix it.
Thanks

Your Catt seems to be an unifoliate, i.e. with only one leaf per growth. This means that what is drying are sheaths from where the blooms come. Some plants bloom from dry sheaths so...wait and see.

In large bark like that watering once a week is probably not enough. When underwatered, new Cattleya growths frequently turn black and die. The problem is not fungal.

Agree... water more often.

rbarata is talking about the smaller thing with rounded end growing at the top of the pseudobulb. Is that what you meant by what is dying? I was writing about new growths coming from the base.

So was I, and thought you were saying you were losing new leaves. I looked at pictures again and don’t see any dying leaves. So I’ll shut up until there’s an explanation.

WW .......could you please shut up ? Oh ..... you already did! And hear me out. I don't want you to shut-up!!! Because you made a good point. I didn't see any dying leaves too. Ok. I'll shut up here hehe

I marked the spots I was talking about.

sperpich - the pics are a bit small, but those circled portions could be dried or drying sheaths, right?

For the images, see if you can make them around 1024 x 768 pixels (width by height), or even 768 x 1024 (width by height). A little larger.

'sheath' for a cattleya orchid is a sail-like structure that has the appearance of a leaf, but is for covering and protecting (or humidifying) the flower buds and spike that is often produced later within the sheath ----- except for really young orchids, where there can be a sheath, but not necessarily resulting later in flower bud/spike development.

Sorry about that. If you go back to the first post you can see it clearly there. Thanks
