When you refer to onions are you talking about onion onions the ones you eat or are you talking about psuedobulbs? That onion thing is confusing me.

The new growth will look the same on most Onc alliance (Tolumnia look different overall, usually no visible pbulbs, and fan shaped growths)

Miltoniopsis do like to be moist. Older pbulbs will wrinkle a bit as new growth comes in. If the new growth is coming in smooth (not pleated), your watering is probably ok. Extremely wrinkled, shriveled, and depleted looking pbulbs could be from under or overwatering. Are you able to post pix?

Miltoniopsis like to be evenly moist and grown in a somewhat shaded position. But if you are going to keep them that way you need to provide good air movement. They can be grown in spagnum moss but not tightly packed. They like to be warm but not above 80f and be careful in winter because they do not like to be cold. I have trouble growing them because it is cool and humid here and they rot easily. They grow just like all the oncidium alliance orchids. Your "onions", pseudobulbs, get wrinkly when they are feeding new growth. The starches and sugars stored in them flow to the new growth and they shrink as they do so. It is normal. When the new growth starts elongating, water a little more and do not let the new growth dry out.

I have never heard anyone refer to pbulbs as "my onions". But what really confused me was that the word pbulb was used in one sentence and then a few sentences later pbulbs were referred to as onions.

What I want to surely ID is the new growth here in the second photo Is that in fact a new growth?

I have my MIltoniopsis sitting on my coffee table getting sun from the west window but pulled far back. The only stronger sun it gets is still cool but in the afternoon the sun shines stronger through that window, see as I dont understand the foot candle thing its been responsive to where its at it bloomed quickly. though i want it to re bloom so I can send a full photo of where its at and the light level if necessary. I do have a 2 fans and a ceiling fan going at all times with my Orchids to a point where the leaves sway a bit. My home never exceeds 80 degrees my temp gauge reds 77 degrees to 75 all day. It is in a humidity tray but unfortunately it only has 33 percent humidity at the highest. Im having a rough time with humidity with my Orchids and what to do.

The third photo is just the back of the Milt and i wanted to show the slight wrinkle thats happening.

The fourth is some yellowing Ive always disliked....is that normal? that is the front side of the Milt.

Thank you guys and Ill respond again if I forgot anything.

That is a new growth. As it gets bigger it will turn into a pbulb. The wrinkling is normal if it is one of the older pbulbs. It also could be from the low humidity. If it is a new pbulb, you might not be watering enough or you are watering too much. They both have the same symptoms. You should try and get a humidifier. Humidity is going to be an issue for you since outside where you live is very dry and hot and inside you have air conditioning which also really dries the air. I don't see anything wrong with the 4th picture. It looks normal.

Yes that's new growth, and the pbulbs look fine. I don't see any yellowing ? These are light green, older foliage will yellow after a time, and drop. It will need stronger light to rebloom.

Here are a few more pics that I wanted you to tell me if shes a healthy plant or not. I see blackness and the tips of my foliage are concerning me. It is deflated as if the tissues are burning but I couldn't be giving it too much sun right? I did look at your pics and they are not flawless but they are still healthy granted, it is nature and it is imperfect I just want to make sure...the only thing I do is, in the morning I put it in VERY bright light but my windows are tinted so I always figured it would compensate. Am I burning my plant now?

TiffanyP · #19 06-08-2012, 01:59 PM

sigh* Well I guess that settles it. Would you all suggest maybe some artificial light then? Or maybe an eastern window with more humidity?

WhiteRabbit · #20 06-08-2012, 02:06 PM

oh - if it's in a bright but tinted east facing window, that might be sufficient - I read where you had it on a table. I don't know how tinted the window is tho - but I have rebloomed one that got some morning sun.

Onc alliance are prone to spots on foliage, especially older foliage. Your plant looks great. What type of media is it potted in?
