Platycerium bifurcatum (plat-i-SEE-ri-um bi-fur-KAH-tum)

Staghorn fern, Stag’s horn fern

Staghorn fern, like many of its fern relatives, is an epiphyte, meaning that, in its natural state, it typically grows on tree trunks, branches and rocks and absorbs nutrients and water from the air. Multiple Platycerium species exist today, including numerous hybrids, but P. bifurcatum is the most common and easiest to grow. It exhibits large, dark-green fronds that fork, causing them to bear a striking resemblance to antlers. For display in the home, the large plants are typically mounted on wood or attached to wire baskets with sphagnum moss or other organic medium covering the root balls. A compact hybrid is also available.

With proper care, these plants can last for several years.

Staghorn ferns are most widely available in spring and summer, but in mild climates, they can be found year-round.

in-store and consumer care
LIGHT Moderate light to partial shade is ideal for this forest-floor dweller. Full sun is likely to burn the plant’s waxy leaves; however, too little light may cause the fern to grow slowly and make it more susceptible to disease.
WATER Regular light waterings, using water at room temperature, are recommended. Because these plants are extremely susceptible to damage from excess watering, some experts suggest that it’s better to allow the plants to show slight wilting before they are watered. Plants will revive quickly once watered, but excess watering is likely to bring a quick end to staghorn fern plants.
TEMPERATUE Some Platycerium species can tolerate cool temperatures, including staghorn fern. Temperatures in excess of 50 F are recommended, and warmer temperatures, from 60 F to 80 F, are ideal.
HUMIDITY Staghorn ferns require high humidity, but they don’t care to be misted. Instead, indirect humidity, from a humidifier or other source, is ideal.
FERTILIZER During warm weather months, from midspring through summer, monthly applications of a balanced plant food, mixed at half strength, can help support new growth.
PROPOGATION Offsets, sometimes called “pups,” can be removed with their root systems intact and then re-established in damp sphagnum moss, but success with these may be difficult. The plants’ fertile fronds (some fronds are sterile) also produce spores, but propagation from these is unlikely for all but the most experienced specialists.
PRUNING No pruning is required, but damaged leaves could be snipped off with sharp scissors. The rounded basal leaves should never be removed, even after they have died, because they provide humus as they decompose.
REPOTTING Replace the sphagnum moss or other organic medium annually.

PESTS AND PROBLEMS Mealybugs and scale insects occasionally infest staghorn ferns. Insecticides are typically effective but can damage the plants, so take care when using these and opt for insecticides that are not oil based. The most common challenge, however, is with excessive watering, which can lead to fungal disease and root rot.
LEAF CONCERNS Black spots on the basal leaves typically indicate a fungus that often results from overwatering. To reduce the damage, suspend watering and reduce humidity. Chemical products to treat the fungal disease are also available.
