Hello all

In thinking about it, one caution I would make with regard to irrigating any 
plant with a hand-held spray mist or the like, is that it should be done to the 
point of run-off and more, so that accumulated salts on the fronds will be 
dissolved and washed off.

Tap water usually contains dissolved salts to a degree not found in rainwater. 

While I can't actually name any salts found in water that I know are harmful 
to foliage, especially the thin filmy fern fronds, I would do this as a 
precautionary measure.
