Polypodium is a fun little fern that is also called rock polypodium or polypodium vulgare. It is native to America and parts of Asia, with some species from Africa. Polypodia fern prefers moist places with some shade and makes an interesting woodland or coastal specimen in the garden. A common variety of fern, Polypodium is an evergreen plant that forms a mat as it matures.
#Care of polypodium
Polypod ferns are short plants that rarely reach more than a foot (0.3 m) in height with a similar arrangement. As with most outdoor fern care, they don't need much attention as long as they are in an area protected from the sun.
#Light
Most polypodial fern species prefer partial or full shade. Deep shade seems ideal where the plant receives 2 or less hours of direct sunlight per day. They work best as underground plants, protected from the sun by trees or other taller species.
#Water
Although these ferns need well-drained soil, they need constant moisture. In the summer heat, plants in the ground should be watered every day. Those in pots may need to be watered twice a day in the summer.
#Temperature and Humidity
Each species has a different level of resistance. Some are hardy to USDA zone 3, while others, such as P. polypodioides and P. vulgaris, are hardy only to USDA zone 6. They prefer temperate areas and generally cooler temperatures.
#Floor
The health of these ferns requires drainage. Polypodium fern is often found in sandy soils, but humus to almost barren soils are also acceptable. Other pteridophyte that can be grown on logs or even rocks includes Easter fern (P. polypodioides).
#Fertilizer
Established plants do not need top dressing, but respond well to a light spring application of a balanced fertilizer. Potted plants should receive a half-diluted fertilizer in the spring and every month until August.
#Problems, pests and diseases
These ferns have no listed pests or diseases. Even rabbits and deer, they can tolerate.
#Cut off
The only necessary pruning of the polypodium is the removal of dead or damaged leaves. Over time, the lower leaves die back to make room for new growth. But simply cut them off at the top of the head.
#Spread out
To propagate ferns, divide the rhizomes in early spring or fall and plant them in a peat/perlite mixture. As the new plant grows, more roots will be produced, so try keeping the mixture moist. Naturally, plants reproduce by dispersing spores.
#Transplantation
Container-bound plants enjoy well-drained soil with coir and perlite or vermiculite. When transplanting, you must carefully remove the plant and reposition it at the same level as it was before. Settling the soil by transplanting water immediately.
#Types
- Polypodium virginianum: Virginia polypody or rock fern is found wild in rocks, cliffs, rocks and on ledges. It has curved, deeply cut leaves and will ripen in clusters of colonies.
- Polypodium polypodioides: Resurrection fern curls and leaves turn brown in hot weather. Just when you think he is dead, colder weather and rain he will rise like Lazarus. This fern should be exposed to very little sun and in a place where the soil is cool and moist.
- Polypodium appalachianum: Appalachian fern forms a dense mat that retains nutrients and moisture. The leaves are lance shaped with the wide base.
- Polypodium virginianum: This fern is similar to the Appalachian stonewort, having widest leaves in its center. The plant is very drought and sun sensitive. It is an epiphyte, the facility for which is rooted in the air promoting the draw of moisture and nutrients. Inhospitable soil or even rocks are often where ferns are found.
- Polypodium vulgare: Native to Africa and Eurasia, this is one of the less hardy polypodiums. In its native area, it is used to produce nougat and is used as a herbal medicine. The leaves are leathery and lance-shaped with clear edges visible on the upper leaves. This fern is known as the common polypod.
