Staghorn ferns are an interesting and unique plant for a warm climate garden, houseplant or greenhouse plant. Eventually, a properly planted fern will spread and form a large ball, completely obscuring the basket. Baskets can be hung from trees or patio eaves. Staghorn fern can be grown outdoors during the warm months in cool climates and year-round where it stays above 25 degrees.
Place a layer of sphagnum moss about 2 or 3 inches thick in the bottom of the wire basket.
Remove the juvenile staghorn ferns from their nursery pots they came in and knock the excess soil from the root balls. Leave as much of the roots intact as possible.
Place three of the staghorn ferns around the bottom of the basket turned almost completely upside down so that the fronds hang out of the bottom sides through the wire and the root ball sits on top of the layer of sphagnum moss inside. Make sure that the sterile shield fronds are on the outside of the wire. Fill the basket with sphagnum moss.
Make a depression in the moss in the top of the basket enough to plant the fourth fern upright and gently pack the moss around the roots. Add more moss so it is packed tightly and the ferns hold in place.
Water thoroughly and let the plant drip dry.
