Description
Platycerium, commonly known as the staghorn fern, is a genus of epiphytic ferns native to tropical and subtropical regions around the world. These ferns are named for their unique fronds that resemble the antlers of a stag. Platycerium is a popular houseplant and is often used in landscaping due to its striking appearance.

Appearance
Platycerium species can vary in size, but most are medium to large-sized ferns. The unique fronds of Platycerium resemble stag horns, with the fertile fronds appearing like the antlers of a stag. The sterile fronds are flat and often heart-shaped or triangular. Platycerium species are typically gray-green or blue-green in color, with some species producing a brown, fuzzy, protective covering on the underside of the fronds. These ferns are epiphytic, meaning they grow on other plants or trees, and do not require soil to grow.
Care Guide
Platycerium ferns require specific care to thrive. Here are some tips:
Water
Platycerium ferns prefer to be watered thoroughly but infrequently. Water the fern when the top 1-2 inches of soil are dry to the touch. Do not allow the fern to sit in standing water, as this can cause root rot.
Fertilization
Fertilize your Platycerium fern every 4-6 weeks during the growing season with a balanced, water-soluble fertilizer. Do not fertilize during the winter months.
Soil
Platycerium ferns do not require soil to grow. Instead, they should be grown in a well-draining potting mix or mounted on a piece of wood or bark. If grown in a potting mix, use a mix of peat moss, perlite, and orchid bark.
Sunlight
Platycerium ferns prefer bright, indirect sunlight. Direct sunlight can scorch the fronds, while too little light can cause the fern to become leggy and weak.
Hardiness Zones
Platycerium ferns are not cold hardy and should be grown indoors or in a greenhouse in cooler climates. They can be grown outdoors in USDA hardiness zones 9-11.
Common Pests & Diseases
Platycerium ferns are generally pest and disease-free. However, they can be susceptible to mealybugs, spider mites, and scale insects. These pests can be treated with an insecticidal soap or neem oil. Overwatering can also lead to root rot, which can be prevented by ensuring the fern is not sitting in standing water.
Habitat
Platycerium ferns are native to tropical and subtropical regions around the world, including Australia, Southeast Asia, Africa, and South America. They are epiphytic, meaning they grow on other plants or trees, and do not require soil to grow.
