Thanks, Planto. I may try outdoor if I can find some suitable spot in my patio.
Thanks, Lin. I don't see "yellowing fronds", but lot "dark, nearly black" leaves hanging and shedding. Is it sign of over-watering? Since the ferns are kind of huge covering from top, side around, to bottom of their pots, I have no way to check the soil in pots. (I guess my hands are not used to handling plants especially the delicate, fragile ones like BF.) I tried to avoid direct sunlight, but really struggle with our extreme high heat in summer. Cranking ac may help a bit to lower temp, but cause even higher dryness losing more humidity and may reversely affect other indoor plants... I only hope they can hold until it becomes cooler later...
