Leaves yellowing from base??

[lauraeli]

Ok this happened almost overnight. This one just got done flowering so I moved it into the other room to be in the east window. It was moved from a dark area of the house. Two days later, THIS! The leaf petioles are turning yellow!

I unpotted it. The roots are healthy, all the way up to the collar of the plant. Not even the roots in the center are showing signs of rot. The collar is alive and firm all the way down to the base. I dont spray or pour water on my phals to water them, I dunk them. So no crown rot.

What should I do? Can the leaves be saved?

Am I worried for nothing? Waiting for opinions before i pot it back up. I dont want to leave it out of the pot forever

I think that leaf is old and time for it to go.

Do old leaves typically yellow from the base outward? There is another leaf next to it with a yellow petiole, as well.

What kind of medium you had this phal planted in? I see some sphag. Check the crow to see if there's anything soft and smelly.

potted in bark. Nothing is soft. I checked up and down the collar and checked the crown as well.

Maybe it is just naturally dying off. Sometimes plants will have a leaf die to enable it to push out new growth, redirect its energy to either another new leaf or root. It is the lower leaf dying , so for me it is okay..I will be more concerned if it is a new leaf in the center that is wilting. Does not really need to be the lowest leaf to first have to go..but it happens.

I hope so. But my understanding is that old leaves die from the tip inwards. This one is dying from the crown out.

You did change the location of your plant, and it will react to that change. Maybe it is accelarating the senescence, combination of factors.

I noticed some other things. In this picture you can see both.

One is, the leaf is already disconnecting from the base of the plant.

The second thing I noticed is that the other leaf petiole has two dark brown spots on it, one on either side of the plant. There is a bump under both. I think it is a root trying to come through. Would that make the petiole turn yellow?
