    :( I purchased this in Oct.'16 from an ebay vendor. It arrived mounted on a piece of tree fern with another plant loose in the package. I potted the loose on in spag. with coconut fiber around the outside in a 2' hydro pot. in Nov.the one on the tree fern developed this and promptly died. The other one has been fine until today. I have never seen this before and don't know what it is. Can anyone help?
    I have a cool to intermediate greenhouse, 50-55 nights and 65-70 days if the sun is shining. I have low light until the sun gets up above the trees on the hill behind my house in mid Jan. I have 80-90% humidity and good air circulation.
    I am attempting to upload two pictures, last week and today. Am not sure that I am doing this right. I can't see the pictures in the post right now but I did select them and they were listed in the selection window. Here goes!

    You've done a wonderful job of carefully potting this up. They don't grow potted. They are twig epiphytes that grow on the tips of outer branches of trees. They get lots of air movement and dry very, very quickly. I grow them on a small piece of hardwood or cork with nothing on the roots. If you had low humidity you might put a bit of moss, but with what you've got, just leave them bare.

    Thanks Marni, is there any way to save this? It looked so good for a while, I thought I had it doing well.

    Marni, If I try again with the P. pusilla what more do I need to do to keep it happy? Are my other growing conditions where they need to be? I have not grown mounted plants before and am on hopefully a quick learning curve. I have a Haraella retrocalla, Den. of unknown name, both mounted and a tiny Neofinetia falcata potted and a Dendrobium lamyaiae potted.

    This is my venture into smaller plants that take up less room and let me grow more different and interesting types of orchids. I have always been drawn to species instead of the big hybrids. Before I found this forum I was flying blind and killed a lot of plants, hope "you all" will help me keep learning. I am astounded at the vast wealth of knowledge that is shared here.

    I have downloaded 4 pictures, don't know if they are here or I am not doing it right. Help with that would be appreciated also.

    I have changed your images from thumbnail attachments to imbedded images so they are easily seen by all. If you do a search for "posting images" searching titles you will come up with 3 that I have posted and probably some from others.

    To answer your question. With your low minimum nights, I don't think Psygmorchis pusilla is not going to do well. I never succeed with them in cool temperatures. If you want to try again, get in in the brightest spot you have and let them dry for a couple of days before watering. They should dry within a few hours of watering.

    Both of your dendrobiums look as if they might benefit from a dry rest this winter. Den lamyaiae definitely needs a dry winter. It depends on how often you water, but I grow Den. lamyaiae in a cool house mounted on cork with almost nothing on the roots once it is established. When I have grown it potted, I have had it in a plastic net pot in a fine bark mix. On treefern with moss and your high humidity it won't dry out between waterings and probably stays wet all winter.

    Your Neofinetia falcata likes a slightly drier winter, but should do well as is. Are there any roots on the Harella and how long have you had it? It looks very stress.

    Hi there,
    Your growing conditions are cold to cool so you can only grow orchid species that can be kept in those conditions.
    Both the Psygmorchis and Haraella are intermediate to warm growing.
    The damage on the Psygmorchis is due to the cold and will not make it I'm afraid. Also this species in nature is very short lived and normally don't live longer than 2 years so I wouldn't recommend it.
    The Haraella on the other hand can be grown easily on the window sill in the house. I grow mine in sphagnum moss, letting it dry before watering again.
    However there's a wide range of orchid species and hybrids that would really do well in cool to cold conditions. Neofinetia is one of them, stays small and is available in many varieties that produce variegated leaves and/or have white, pink or yellow flowers. If you're into Dendrobium, D. moniliforme is a good choice. A compact grower and also available in many varieties as N. falcata. Most are also inexpensive so you can build a nice collection. D. parishii is a compact grower too. All mentioned have very nice fragrant flowers. Then there are many South American species too for your growing area like Masdevallia, Restrepia and Sophronitis species.
    Before buying new orchids, check if your growing conditions are suitable.
    One more tip; Neofinetia needs airflow around the roots so use an open basket for growing them, when moss is used, the center of the pot must be open so air can circulate around the roots and they can dry quickly otherwise the roots will rot. Do not use coconut fiber.

    Thanks for all the info, sorry my pictures were thumbnail.When I do as suggested with the photos I do not get a screen that gives me any options. It is totally different than the one in Marni's post. I get a small black screen with a line that says select a file, that opens my iPhoto where I see my shots and pick one, I have to go back in to pick each one separately. I don't like the thumbnails either and would really like to post full size ones. I don't know maybe I have a weird Mac.
    I'll go in now and see if I get anything different.

    I'm on a Mac too, that isn't the problem. When you want to put an image in your post, put your cursor where you want the image(s) to be inserted. Click and drag the image into the text box and it will change to a box that says "Drop images here" or some such thing. Scroll down until you see the thumbnails below your text box. Click "Full size" to the far right of each image and that will imbed the images in the text where the cursor is.

    You can also do it by going the through the "upload a file" button and then click "Full image" below the text box. You can move more than one image at a time by simply selecting all that you want to move.
