The family of kostentsovykh. According to various sources, the genus numbers from several tens to several hundred species. All of them are predominantly herbaceous plants, leading a terrestrial, rocky or epiphytic lifestyle. Leaves can be whole or feathery, the rhizome is either short vertical (in epiphytes) or creeping (in terrestrial ones). Many species are still in question, the names have not been approved and are disputed by biologists for their relation to other genera of ferns.
Asplenium nidus is the most widespread species. This epiphytic fern resembles bromeliads with its leaves collected in a rosette. It has large, wide, light green leaves. Asplenium is a fast growing plant. With good care, its leaves reach 60-100 cm. With age, the plant grows strongly in width, because new leaves are constantly forming from the center of the rosette. Dislikes when leaves are touched.
Also grown in culture is the species Asplenium bulbiferum. This view looks completely different. It has feathery, highly dissected leaves on which numerous babies develop, and its stems are like a wire.
Asplenium - care
Temperature: Aspleniums are thermophilic ferns, it is desirable that the temperature during the growth period was about 20-25 ° C, slightly cooler in winter, but not lower than 18 ° C. Asplenium does not tolerate drafts!
Lighting: The area for the asplenium should be light enough, but shaded from direct sunlight, a north, east and northeast window works well. Do not place the plant in the back of the room - in nature, asplenium grows under the shade of the openwork crown of trees, but not in a gloomy shade.
Watering: Watering plentifully from spring to autumn and moderate in winter. Instead of regular watering, it is recommended to immerse the plant pots in a bowl of water from time to time. Asplenium does not tolerate hard and chlorinated water; for irrigation, use water at room temperature, settled for at least 12 hours (preferably boiled or filtered).
Fertilization: Top dressing is carried out once a month from April to September with a weakly concentrated solution of fertilizers (approximately half the dose for plants such as philodendrons or ficuses).
Air humidity: Aspleniums need humid air, about 60%. In dry air, the leaves of the plant dry out. It is best to place on a wide pallet covered with expanded clay or gravel. They also water the soil in the pot and pour water into the pan. If there is a central heating radiator nearby, it should always be covered with a damp sheet.
Transfer: The soil should have a slightly acidic reaction. The soil is loose: 1 part leaf, 2 pine bark, 0.5 part humus soil and 1 part coconut substrate, high drainage is required at the bottom of the pot. Transplanted annually or every other year. Does not tolerate planting in too large a container and in heavy clay soil. You can use a commercial orchid potting mix. It is very important that the soil of the asplenium dries out quickly, is loose and airy. The roots must breathe! Therefore, small holes can be made in the walls of the pot for epiphytic aspleniums.
Reproduction of asplenium
Asplenium is propagated, like all other ferns at home, by dividing the bush. Remove the plant from the pot, lightly wrap an earthen ball with your hands, then separate the leaf with a small lump of roots from the side of the root ball, cut off with a sharp knife. Plant the cuttings in a small pot in loose soil. Any general purpose primer from the store will do, such as Terra Vita. After planting, the children of the ferns grow slowly, they do not need to be fed, you can only spray them with epin or a weak solution of zircon. But after a month, more active growth begins.
