Bump! To throw some light over your way Jesse from here in winter England Uk, to battle the frost keep moisture levels reduced. Some plant tropics can overwinter outside here if kept a lot dryer but will sustain some degree of damage which will affect the aesthetic value at the very least but not kill it and as favourable weather conditions return new growth hides the old. More specifically for orchids, many tropical ones wouldnt survive very long at all unless its our hardy natives. Tree fern stumps, palms, some banana sp are wrapped in straw (hay), newspaper, bubble wrap to act as insulation. We use specialist fleece, atype of synthtic fibre woven fabric.
Moving to shelter/ garage/ shed or house is unfortunately the only solution for some and a make do temporary enclosure improvised with tools and household stuff lying about. My cymbidiums have never experienced frost but have tolerate cold temps but above the frozen mark.
