Staghorn Fern Care at a Glance
Common name: Staghorn fern, Elkhorn fern Scientific name: Platycerium spp. Soil: Well-draining organic medium Light: Bright, indirect sunlight Water: Medium Food: General-purpose liquid fertilizer Temperature and humidity: 60 to 80 degrees Fahrenheit, 70 percent relative humidity Propagation: Division, pups, or spores Safety: Nontoxic, low allergen
Staghorn Fern Characteristics
Staghorn fern is the generic name for any of 18 fern species in the Platycerium genus. The botanical name is derived from the Greek “platys,” which means “broad,” and “keras,” meaning “horn.” Most are native to Australia, the South Pacific, and Southeast Asia, but a few grow in tropical Africa, Madagascar, and South America as well. The species that Westerners are most familiar with is P. bifurcatum, which is sometimes called Elkhorn fern.
Staghorn ferns, occasionally referred to as “stag head fern,” are so called for their resemblance to antlers. The stag plant is typically mounted to a wooden plaque and displayed by hanging on a wall. The plants grow best in warm, humid conditions, indoors or out.
In the wild, these ferns are either epiphytes (they grow on trees), or lithophytes (they grow on rocks). They attach to tree bark via tufted roots that grow from a rhizome. Shield- or kidney-shaped basal fronds growing from the rhizome laminate against the tree, protecting the fern’s roots from damage and drying out. Fertile fronds jut out from the base, taking on the characteristic antler-like appearance and bearing spores on their lower surface.

Types of Staghorn Ferns
- Elkhorn fern (P. alcicorne) produces domed shield fronds that hug the roots, and slender antler fronds with lots of small branches at the tips.
- American Staghorn fern (P. andinum) displays short, upright, antler-like basal fronds along with longer, slender, drooping fertile fronds, and lots of pups.
- Staghorn fern (P. bifurcatum), the most widely grown species, produces heart-shaped basal fronds and long, arched antler fronds.
- Crown Staghorn (P. coronarium) produces a pronounced upright basal crown-like frond and weeping antler fronds.
- Elephant Ear Staghorn fern (P. elephantotis) displays rounded, almost cabbage-like fronds without the forking seen in other Platycerium species.
- Triangle Staghorn fern (P. stemaria) grows tall, wide, wavy basal fronds and drooping antler fronds that appear like the letter “Y,” with its top reaching for the ground.
- Staghorn fern (P. superbum) produces a large, nest-like basal frond and broad antler fronds.
Selecting Soil for Staghorn Ferns
As epiphytes, staghorn ferns prefer a coarse, well-draining growing medium that is high in organic matter. Instead of growing them as potted plants, most growers mount them on wood planks, or plaques. Cedar makes an excellent staghorn fern mounting board because it is naturally rot resistant. The medium of choice is dried sphagnum moss.
To mount the stag plant on wood, start with a mature fern and a plaque with four or five mounting screws secured on the front. Gently remove the fern from its pot and break up the bottom third of the root ball. Place the plant in the center of the plaque with the antler fronds oriented toward the top.

The Right Light
Like most popular indoor plants, staghorn ferns need bright, indirect sunlight. A good location might be a room with east-, south-, or west-facing windows. Just be sure to protect the plant from direct sunlight, either by shielding it with sheer curtains or by placing it on the opposite side of the room from the windows.
In a north-facing room, it can sit very near the window. To test the light level, hold your hand over the spot where the plant will sit. If your hand casts a shadow, the lighting is adequate.
Watering Staghorn Ferns
Weekly watering is generally adequate for staghorn ferns during summer and every 2 to 3 weeks in winter. This could change with the potting medium, temperature, and humidity of the room, among other factors, so adjust as needed.
Mist the foliage regularly to boost humidity. Stags actually absorb water through their fronds, so mist will extend the time between waterings. When you water, soak the root ball thoroughly. Place potted plants in a bowl of water and let them soak for 15 minutes or so. Place plaques in a sink and run water over the root ball until it is well soaked. Allow plants to drain thoroughly before returning them to their homes.
If staghorn fern brown leaves are a problem, it is probably a watering issue. Stag plants are sensitive to both overwatering and under-watering. When fronds begin to turn dark at the base, it’s a symptom of overwatering. Brown frond tips and wilting are signs of under-watering.
Fertilizing Staghorn Ferns
There is no need to look for a specialized staghorn fern fertilizer. Stags thrive on weak applications of general-purpose liquid plant food during the growing season. Do not fertilize in winter.
Mix a balanced fertilizer, such as 10-10-10 or 20-20-20, at quarter or half strength and apply it during the normal watering schedule. If the manufacturer’s instructions are for monthly feedings, mix the fertilizer at quarter strength for weekly watering, or half strength for biweekly watering.
Setting the Temperature and Humidity
Staghorn ferns grow well in average home temperatures between 60 and 80 degrees. During temperate summers, they appreciate the heat and humidity outdoors, but be sure to avoid direct sunlight. Move them back inside when night temperatures drop into the 50s.
High humidity is vital for good staghorn plant health. Keep the plant away from heat vents, fireplaces, and other arid zones. Mist the fronds daily to boost the ambient humidity. If the fronds begin to brown at the tips, but the root ball is still moist, mist more frequently. Consider moving the plant to a bathroom, or even the shower, for a humidity boost.

Propagating Staghorn Ferns
If you have a mature staghorn fern, you might be able to grow additional plants from it. Staghorn ferns are typically propagated by spores or by division of pups.
Spores are the equivalent of tiny seeds that grow on the undersides of fern fronds. They can be harvested and started in sterilized seed starting mix. There are several ways to do it, but all are somewhat complicated and it takes at least a year before the baby plants are large enough to transplant.
Mature stags may produce pups near their base. Pups are baby plants that grow from the same rhizome as the parent plant. Closely examine the soil area around and between the basal fronds of mature plants. If you find smaller, developing plants, you can carefully separate them to pot up. For a strong staghorn fern colony, thin the pups to allow 3 inches of space between plants.
Staghorn ferns are considered safe plants to grow around children and pets; they exhibit no toxicity to humans, dogs, or cats. They do not flower, so pollen is not a problem. Some individuals might be sensitive to mature spores, which could cause an allergy flare-up.
Potential Pests and Diseases
Stags are resilient plants that exhibit almost no pest or disease problems. If the plant is stressed, typically due to overwatering or under-watering, scale insects could infest a staghorn fern. Also, overwatering can cause root rot. Providing a combination of adequate lighting, temperature, humidity, and water is the best way to avoid these problems.
FAQs About Staghorn Fern Care
Inquisitive gardeners want all the information available. Following are some of the most frequently asked questions about growing staghorn ferns.
Q. Do staghorn ferns need soil?
In their natural habitat, staghorns are epiphytes that grow on the sides of trees without soil. Many gardeners replicate this environment by mounting them on wood plaques.
Q. Can staghorn ferns grow in soil?
Staghorn ferns can grow in pots, but they should not be planted in mineral soil. Instead, use a well-draining planting medium made primarily of organic matter. A 50/50 mixture of orchid bark and cactus potting mix is appropriate.
Q. How do I plant a staghorn fern?
Young plants can grow in pots filled with a mixture of orchid bark and cactus potting mix. Mature plants grow well when mounted on cedar plaques, with their roots covered in moistened sphagnum moss.
Q. Are coffee grounds good for staghorn ferns?
In limited amounts, coffee grounds can help boost soil acidity and organic content of the growing media. But they should not be viewed as a replacement for either proper fertilization or an appropriate planting mix.
Q. Are banana peels good for staghorn ferns?
As with coffee grounds, banana peels may add trace nutrients that staghorn ferns can use, but they cannot replace proper fertilization. Plus, banana peels will attract fruit flies as they decay.
