Well, they seem so fancy and delicate but believe us that they are equally easy to care for and hardy than most ferns out there. They do well in medium to bright light, but with weekly watering and mainly soaking. Yeah, they do like a good bath.
Weekly, when the potting mix is half dry to dry, about 2" down the pot. When planted on a mount, keep it moist evenly when seems dry. "They love misting"
Well draining potting mix with compost, leaf mould, cocopeat and a little bit of perlite if available to increase the aeration.
If mounting on a mount, you can use moss only.
Wheyou think of ferns, most of them prefer the shady, lush forest floors. You might then think that your stag will appreciate a dark space, but NO Staghorn ferns, on the otherhand, are native to the tropics.
Staghorn ferns need bright, indirect or diffused light to thrive, though they must be protected from the harsh rays of the direct sun.
