Elkhorn ferns are epiphytic plants (they grow on trees) that obtain water and nutrients from the air rather than the soil. They get their name because the fronds supposedly resemble the forked antlers of male deer or elk. These guys are unusually big and impressive - 110 cm wide and in 21cm pot!! They can be grown in a pot, in a wire basket but most people grow them on a piece of wood, they prefer to grow this way because it allows for maximum air circulation.
Elkhorn ferns need bright, indirect light to thrive, they must be protected from the harsh rays of the direct sun. Put your Elkhorn in the brightest spot in your home that does not get direct sun.
Elkhorn ferns are from tropical rainforests, to mimic this environment use a spray-bottle that emits a fine, ambient mist, such as a brass mister. They absorb water through their fronds, as well as their roots. Mist the entire plant, focusing on the underside of the antler fronds and the shield fronds.
Dunk your staghorn fern in a sink or basin of water for about a minute, or until the plant's roots are fully saturated then drip dry before re-hanging. do this once a week in the summer and every 3 weeks in the winter, roots should never completely dry out.
