Cambria I am not that familiar with western KY. I've been to Paducah, Owensboro and driven through western KY to get to MO or Arkansas don't know Daviess Co. I am in Fayette County.
Mary Linn my vaginatum is mounted on a tree fern totem and gets watered daily, even when it is gray and ugly outside.
I have two different tingabarinum - one was from Andy and mounted on one of his sticks and I couldn't keep it wet enough. I scraped it off and mounted it on tree fern and it gets watered daily.
The other tinga is the yellow form and I grow it in a net pot in sphag and it gets watered every 2/3 days - both get Catt light.
I had a wendlandianum, notice I said had. It is a Bulbo that needs a much drier winter. I grew it wet except in the winter months and would only give it sips of water on sunny days. I couldn't get it to flower very much for the size of the plant and gave it away.
Since I didn't get it to flower very well I would take my advice with a grain of salt. Hopefully someone else has been successful and give you better advice.
