So, again, another inquiry into another member of the Oncidinae, or members of the complex Inter-genetic Oncidium group of orchids. This time, I am more interesting in horticultural over taxonomical concerns. My inquiry entails Oncidioda Charlesworthii 'Mishima'

Several times, I have purchased Oncidioda Charlesworthii 'Mishima' only to have it perish rather quickly. I have attributed it to certain ways in which it has treated by myself. Recently, when I did an annotated inventory on the plants in my collection, I included Oncidioda Charlesworthii 'Mishima' because I had just been fooled by beauty once again and thought, perhaps, I could finally, reasonably learn how to grow this orchid.

When I annotated this Oncidinae member, I made a big discover! Whereas I live in a warm-growing climate in Tidewater, VA; Oncidioda Charlesworthii 'Mishima' prefers cool-growing growing conditions with a tolerance of intermediate temperatures. (Does this fit with others' understanding of the plant?) For that seems to be the reason why I have had such difficulty with the plant, I should think?

Now the fresh looking Oncidioda Charlesworthii 'Mishima' that I purchased two weeks ago looks like in bad shape, "a raven at my window with a broken wing," to quote Bob Dylan. The leaves are either dropping totally from the pseudobulbs or darkening at the tips, slowly working down the leaf. The flowers have suffered too. I have seen this before! Is my Oncidioda Charlesworthii 'Mishima' doomed?

Does anyone have any immediate first-aid ideas that could revive the plant? And, if it should live beyond this clearly stressed state, any idea on a long term solution other than not purchasing it again to keep it living?

I know a few tricks for cool-intermediate growing plants that I have learned from cultivating Begonia. For instance, these cool growers should be placed on the bottom shelve rather than the top shelve of my light garden, is one strategy. But really I am at a loss, likely in plant, with what to do for this cool to intermediate growing Oncidioda Charlesworthii 'Mishima'!

Again many thanks for reading!
