Platycerium Hillii

A Comprehensive Guide to Growing and Caring for Platycerium Hillii (Hill's Staghorn Fern) Including Propagation and Common Problems

Platycerium hillii, commonly known as Hill's staghorn fern, is a unique and beautiful plant that belongs to the Platycerium genus of ferns. This epiphytic fern is native to the rainforests of Australia, where it grows on tree trunks and branches. Hill's staghorn fern has distinctive fronds that resemble antlers, giving it a distinctive appearance that makes it a popular choice for indoor and outdoor gardens. In this guide, we will provide a detailed overview of Platycerium hillii, including its care requirements, propagation, and other important information.


Platycerium hillii is a large fern with two types of fronds: basal fronds and sterile fronds. The basal fronds are shaped like a shield and are brown in color. They attach the plant to the tree trunk or branch and absorb nutrients and water from the surrounding environment. The sterile fronds, on the other hand, are the distinctive antler-shaped fronds that give the plant its common name. These fronds can grow up to 1 meter (3.3 feet) in length and 30 centimeters (1 foot) in width. They are light green in color and have a rough texture.

Platycerium hillii is an epiphytic fern, which means that it grows on other plants but does not harm them. In the wild, it attaches itself to the bark of trees and absorbs nutrients and water from the surrounding environment. It is important to note that Hill's staghorn fern is not a parasitic plant, and it does not harm the host plant in any way.

Growing Conditions

Platycerium hillii is a hardy plant that is relatively easy to grow. It thrives in warm, humid environments and requires plenty of bright, indirect light. Here are the ideal growing conditions for Hill's staghorn fern:

Light: Platycerium hillii requires bright, indirect light to thrive. It should not be exposed to direct sunlight, as this can damage the fronds. The best location for Hill's staghorn fern is near a north-facing window, where it can receive plenty of indirect light.

Temperature: Hill's staghorn fern prefers warm temperatures between 18-27°C (64-81°F). It can tolerate slightly cooler temperatures, but it should not be exposed to temperatures below 10°C (50°F).

Humidity: Platycerium hillii requires high humidity levels to thrive. The ideal humidity range for this plant is between 60-80%. If the air in your home is dry, you can increase humidity levels by placing a humidifier near the plant or by misting the fronds with water.

Soil: Hill's staghorn fern is an epiphytic plant and does not require soil to grow. Instead, it attaches itself to other plants or objects, such as a wooden plaque or a wire basket. You can use a mixture of sphagnum moss and coconut coir to attach the plant to its support.

Watering: Platycerium hillii requires regular watering to stay healthy. It is important to keep the basal fronds moist at all times, as they absorb water and nutrients from the surrounding environment. You can water the plant by misting the fronds with water or by soaking the basal fronds in water for several hours. Be sure to allow the fronds to dry completely before watering again.

Fertilizer: Hill's staghorn fern requires regular fertilization to stay healthy. You can use a liquid fertilizer that is designed for epiphytic plants, such as a bromeliad or orchid fertilizer. Apply the fertilizer to the basal fronds every 4-6 weeks during the growing season (spring and summer) and reduce fertilizer application during the winter months.


Platycerium hillii can be propagated through spores or by dividing the plant. Here are the steps for propagating Hill's staghorn fern:

Propagation by Spores:

Step 1: Wait for the spores to mature: Mature spores will be brown in color and can be found on the underside of the sterile fronds.

Step 2: Collect the spores: Cut off a mature frond and place it in a paper bag. Shake the bag gently to collect the spores.

Step 3: Prepare a growing medium: Mix equal parts of peat moss, sand, and perlite to create a well-draining growing medium.

Step 4: Sow the spores: Sprinkle the spores onto the growing medium and mist lightly with water.

Step 5: Cover the container: Cover the container with plastic wrap to create a humid environment.

Step 6: Wait for the spores to germinate: The spores will germinate in 2-3 weeks. Once they have germinated, remove the plastic wrap and place the container in a bright, indirect light.

Step 7: Transplant the seedlings: When the seedlings have grown several fronds, you can transplant them into their own containers.

Propagation by Division:

Step 1: Choose a mature plant: Choose a mature Hill's staghorn fern with multiple fronds.

Step 2: Remove the plant from its support: Gently remove the plant from its support and remove any dead fronds.

Step 3: Divide the plant: Use a sharp knife to divide the plant into several smaller sections. Each section should have at least one basal frond and one sterile frond.

Step 4: Attach the divisions to their own support: Attach each division to its own support, such as a wooden plaque or wire basket.

Step 5: Water the divisions: Water the divisions thoroughly and keep them in a bright, indirect light.

Common Problems

Platycerium hillii is a relatively low-maintenance plant, but it can be susceptible to a few common problems. Here are some issues you may encounter when growing Hill's staghorn fern:

Dry or Brown Fronds: If the fronds of your Hill's staghorn fern are dry or turning brown, it may be a sign that the plant is not receiving enough water. Try misting the fronds more often or soaking the basal fronds in water for longer periods.

Yellowing Fronds: If the fronds of your Hill's staghorn fern are turning yellow, it may be a sign that the plant is receiving too much direct sunlight. Move the plant to a shadier location to prevent further damage.

Pest Infestations: Hill's staghorn fern can be susceptible to pest infestations, such as mealybugs or scale insects. You can treat these pests by spraying the plant with a mixture of water and dish soap or by using an insecticidal soap.


Platycerium hillii is a unique and beautiful plant that is relatively easy to care for. With the right growing conditions and proper care, Hill's staghorn fern can thrive indoors or outdoors and add a unique touch to any garden. Remember to provide plenty of bright, indirect light, high humidity levels, and regular watering and fertilization. With these tips, you can enjoy the beauty of this unusual plant for years to come.
