Look, between those trees!
It’s a deer! No- it’s a moose! No, it’s-
A staghorn fern, belonging to the genus Platycerium!
You might be surprised by the association of a tropical fern species to animals which usually dwell in more temperate regions. However, the striking semblance of Platycerium foliar fronds to stag antlers allows for a much more transparent delineation. After all, who can oppose the majesty of fronds nearly half of a meter in length?
Platycerium: An Introduction
Platycerium hail from tropical (and some temperate) regions of the globe, including Africa, Australia, South America, Southeast Asia, and in the southernmost portions of the U.S. state, Florida. Presently, there are eighteen identified species of the genus, but, as stated by the University of Florida, many cultivars and hybrids have made their way to the list of all Platycerium. In their natural habitats, these striking specimens can be found lodged within the cracks of rock faces or mounted to the sides of trees; such eccentric- and soil-less, might I add- growth patterns allow the genus’ species to be classified as epiphytes. Within this soil-free lifestyle, specimens survive by extracting water and nutrients from their surroundings, primarily through the basal fronds and root system, which is protected by the fronds’ shield-like structure.
The configuration of Platycerium is intriguing in its own regard, as can be deduced from the basal frond structure and function described in the paragraph above. Aside from their less-ornate and more heavily-structured basal fronds, Platycerium have ornate foliar fronds which protrude from the plant’s hive-like mounting center. Foliar fronds, as their name clearly states, are the foliage portion of the plant intended for reproductive purposes. Fuzzy, wax-like substances coat the foliar fronds of staghorn ferns and spores can be located on their undersides.
Whether they are grown in their humid natural habitat or in the (slightly) more arid confines of a bright-but-indirectly-lit apartment, staghorn ferns can grow to be a full meter in diameter, despite their distant height from the ground. This impressive size make them quite a spectacle to see in any abode (or in nature) and the definitive uniqueness of the plants have caused them to mount onto the hearts of urban junglists across the world.
Care Practices
First and foremost, these specimens are not particular fond of soil, as they are epiphytes. Well-draining soil can be used to plant these ferns, but they genuinely prefer to sink their roots into a well-draining medium like sheet or sphagnum moss. Specimens can be mounted on a plaque (as shown below) or in a pot.
Watering practices are a bit particular if one has selected to mount their fern, but otherwise, watering is not quite so exciting a venture. To water a specimen, (be it mounted or potted) pour water over all parts of the plant, as it is absorbed by each of the front persuasions as well as the root system. This should be done once every week (to week and a half) in hot, sunny weather, but can be toned down to once every two weeks in cool and cloudy weather. It is absolutely essential that you do not over-water any staghorn fern specimen! The University of Florida actually suggests that plants do best when allowed to wilt gently between waterings. Humidity is another water-involving factor which contributes to the overall well-being of specimens, and ferns should be kept in comfortably humid conditions.
In regards to fertilization and nutritional care, a variety of tricks lie in store to keep staghorn fern specimens on their A-game. As per usual, a fifty-percent dilute solution of 20-20-20 fertilizer can be used bi-weekly to properly feed any specimen. Another, slightly more peculiar practice, is to insert a banana peel behind the basal fronds of the plant where debris would collect if the plant were in its natural habitat. This positioning allows specimens to utilize the nutrients found in the decomposing matter, as is natural to their epiphytic nature. Banana peels in particular are used for their high values of phosphorus and potassium. For more information about this fertilization process, read SF Gate‘s article “How to Feed Bananas to Staghorn Ferns.”
The sunlight and temperature needs of Platycerium are very much attributable to their tropical habitat and epiphytic lifestyle. Plants thrive in bright, indirect sunlight, and should really be under these conditions for four to seven hours per day. Regarding temperature conditions, ferns shoud be kept well above freezing in the range between 50 to 90 degrees Fahrenheit, but should be monitored when conditions approach either end of the spectrum.
