Miltonia Andrea has yellow leaves, help

[LisaMarie]

I recently bought a miltonia andrea and it was/is in bloom. I have noticed that the leaves are yellowing, starting at the root and going upward. It started with just one leaf and now it is several. I am a complete newbie with orchids, and all my other ones are different than this. I read and thought maybe it was too dry so I watered it and it seems to be worse. Help I read that these require more water than other orchids. My other ones I water every two weeks and they are doing beautifully! Any help would be appreciated...

I know that many people still call this a Mitlonia when in reality it is now called a Miltoniopsis.

Your plant should actually be called: Miltoniopsis Andrea West

Q: Why is the naming such a big deal?

A: Miltonia have different care requirements than Miltoniopsis do. If you're getting information on the web for Miltonia when you really have a Miltoniopsis, that might be incorrect care information.

Miltoniopsis like it on the cooler side. The temperatures should ideally not be above 80 F - 85 F on the high end. On the low end, they can take it down all the way to 36 F, but I think a much safer low end temperature is about 45 F.

Miltoniopsis grow under moderately bright indirect light.

Miltoniopsis like consistent moisture, however, do not keep these sopping wet. They can rot out if the media is kept sopping wet. The roots need to breathe.

In order to attempt to strike a balance between air and water, firstly, reduce the pot size to one that fits the root mass - not the pseudobulbs or leaves.

Secondly, use a potting media that provides enough air circulation to the roots, but can retain a good amount of water. Small grade wood chips can work or some tree fern fiber. I prefer not to use moss.

Third, use a pot that has plenty of air slots.

You might want to post 4 more times and then post up a photo to show us what condition your specific plant is in.

I suspect your plant is rotting out because it is being grown too wet. When you describe the pseudobulbs and leaves turning yellow or orange, (particularly when this presents itself in a large number of pseudobulbs and leaves over a very brief period of time), those were my clues without having to see the plant at all. It'd still be preferable to see what the plant looks like currently via photo.

You are correct in the name being "milto.. andrea west" and I will try the things you mentioned. Temperature is appropriate, it sits in a window with light filtered through a sheer curtain, but not sure it is getting enough "air slots". I will try that and thank you for your response and the insight you provided, I appreciate it!

If you're not sure what I'm referring to, this is the best example of what I mean:
