Here in the southeast we get an abundance of rain, 5" in one fell swoop is not unusual and in some seasons a downpour every afternoon is routine. My orchids seem to thrive in these drenchings. I guess it is important to learn where it was said not to wet the foliage? While not one of them myself, we do have some real orchid experts here, some professional growers and a few AOS judges also. They know their stuff and you can be confident in their recommendations. .
