Beautiful green it should in our rooms, and please the whole year! And that is exactly why furs as evergreen exotics belong to our absolute favorites. They are not only beautiful to look at but also good for the indoor climate. We give tips for the care of ferns and introduce you to the five most beautiful species.
So grow fern ferns wonderful
In nature, exotic ferns often grow among ferns in rainforests, on river banks, on mossy stones or on tree trunks. In our apartments Zimmerfarne like bright to shady, but spurn direct sunlight. For your ferns, look for high-quality, but nutrient-poor potting soil - with sensitive species, potting soil with sand content is often the best choice. The soil should always be loose, so that the room warm, preferably lime-free irrigation water can go through well. Although ferns love moisture, they are very damaging to waterlogging.
As children of the forest, ferns prefer high humidity. Avoid drafts and dry heating air. You are welcome to spray room ferns with soft water or rainwater. However, with limy water, the fronds get white spots and some species do not like being sprayed at all. These can be placed near small wells or water bowls. As far as the nutritional requirements are concerned, furs are very frugal - a supply of liquid fertilizer is sufficient twice a month. Occasionally, lice appear as pests. Brown spots or streaks under the leaves, on the other hand, are no cause for concern, as these are the so-called spore capsules. In them spores are growing, with the help of which ferns multiply.
The sword fern has been in horticultural culture for almost 200 years. Originally it was at home in the tropical areas of Africa, America and Asia. Its approximately 30 kinds form the family of the Schwertfarngewächse (Nephrolepidaceae), the most well-known kind for the room is the upright sword fern (Nephrolepis exaltata). The light green, feathery leaves grow up to 150 centimeters long. From a rosette, the fronds grow upright to slightly overhanging. The leaflets can be rotated, wavy or curled depending on the variety. Smoother plumage has the tropical corded sword fern (Nephrolepis cordifolia), which is also common as a room fern.
Sword ferns are also suitable for beginners as particularly easy-care room ferns. They tolerate more direct sunlight than most other species
With its long fronds, the ferns, as imposing solitaires, stand out well in traffic lights or on pillars. It forms filiform foothills, on which small children form. To propagate, simply separate them in the summer and put them in small pots. Adult ferns should repot every three years in spring.
bird's nest fern
The nest fern (Aspenium nidus) carries up to a meter long and 15 centimeters wide fronds with dark midrib. They are undivided, elegantly wavy and have a very shiny surface. As they all spring from a central vegetation point, they form a funnel-shaped rosette - the "nest".
The nest fern is a very elegant appearance
Nest ferns are among the ferns that get along with extremely little light. They have a year round warm location with temperatures between 18 and 20 degrees and high humidity. If the tips and edges of the fronds turn brown, this is usually due to too dry air or poor water supply. Nest ferns have a relatively high water requirement - they should be watered several times a week and occasionally dipped. Since the ferns are a little sensitive to lime, they are best poured with tempered rain water.
Shiny, thin, black-brown petioles and countless fine, rounded, fresh green leaves - the maidenhair fern (Adiantum raddianum) is characterized by its delicate and filigree appearance. Its pinnate leaves grow first as upright, later overhanging fronds, which are up to 50 centimeters long. But in addition to its graceful growth, the fern has another interesting peculiarity: water pearls off its pinnate leaves.
The maidenhair fern forms particularly delicate fronds
There are female hairy ferns all over the world: while some species are common in the Alps, others feel comfortable in tropical rainforests. Specimens that are kept as houseplants are among the non-hardy plants. The ideal location for this elegant fern is the bathroom, because it feels right at home in the high humidity.
The Pellefarn (Pellaea rotundifolia), also known as Knopffarn, would probably not necessarily be assigned to the ferns: Instead of filigree fronds it has thick, shiny, leathery pinnules with a reddish bud.Also, he is only about 20 inches high. The dark, simply feathered fronds often crawl flat along the ground in the outer area, the inner fronds also grow barely upright, but spread horizontally.
The Pellefarn is an unusual eye-catcher among the ferns with its shiny leaves. In winter you should pay attention to spider mites
The Pellefarn belongs to the family of the Felzfarngewächse (Sinopteridaceae) and also its characteristics distinguish it from other Zimmerfarnen: Thus it is relatively robust and tolerates even dry heating air and normal tap water. You should always keep it slightly damp - thanks to its leathery foliage, it can withstand even short dry periods. In winter, the temperature may also drop to up to twelve degrees. Put it in a bright place - if it is too dark, it will throw off its leaves.
The antler fern (Platycerium) looks somewhat bizarre and resembles more a sculpture than a plant: its green leaves can be up to a meter long and branch out with age as an antler. On its underside, the Sporenkapseln, which requires the Zimmerfarn for reproduction. They are characterized by unusually large, dark brown to black areas. In addition to these characteristic fronds, the fern also has coat leaves that turn brown and die over time. These should not be removed as they act as humus and water storage.
With its striking fronds, the antler fern is wonderful as a traffic light plant. Their waxy surface always looks a bit dusty - do not wipe the fronds to avoid damaging the protective wax layer
This room fern is native to all tropical rainforests on earth. There it grows as an epiphyte on trunks or in the branch forks of large trees. In our latitudes, the antler fern also feels good in pots and is the ideal traffic light plant. You can also keep it well in heated rooms with dry air. The reason: The leaves have a waxy surface that protects them from excessive evaporation. You should not spray this room fern with water, better put it once a week for 10 to 15 minutes in room-warm water. In winter, a watering is sufficient for about ten days.
