Have a sloping area?
You need to dig out a large area where water can drain away from. that is why a sloping area would be better than a flat area.
Also you need to use a more permanent very slow degrade-able substrate, probably a coarse granitic gravel with an addition of pumice (lava rock) if available from a local landscaping materials firm. And to that blend add compost at 2 parts gravel mix to 1 part compost.
Plant the cyp (actually a paphiopedilum) slight above the surface of the substrate, mound some of the gravel around the exposed base of the plant and top-dress the entire area with shredded bark used in walk-ways. Use a fine water breaker to water early in the AM.
Depending upon heat and wind in your area you may want to just mist down the area daily but only water every 3 or 4 days.
The plants can handle some drying provided humidity, given by misting, is sufficient.
Good luck.

That is a real crap shoot. If you have a frost free area with excellent drainage it might survive but I suspect it will be more of a gradual decline.
