Why are the fronds on my staghorn fern turning dry and brown. These ferns are outside in a pool cage. I have had them for years, one is 6 ft. across and 4 ft. top to bottom. I water them every other day with my orchids. I live in southwest Florida, so I think the climate would be ok.
It is normal for the flat leaves to turn brown and papery with age.
It is best to water as needed, not on a schedule.
