Asplenium Plant Care

The decorative-deciduous plant Asplenium belongs to the Kostentsovye family and is a fern. It is quite popular with flower growers. This fern is native to Southeast Asia, Australia, and Malaysia. Asplenium feels great both outdoors and at home. If favorable conditions are created for the bush, it will grow thick and rather large: width and height vary from 0.3 to 0.9 m. The foliage has a bright green color, it can be pinnately dissected or simple.

Experts have found about 650 species of Asplenium, but only a small part is raised at home. If a plant is properly cared for, it can live for about 10 years. This fern does not form flowers, but it has very beautiful leaves. It is grown not only in indoor conditions but also in offices, as well as in various administrative institutions and premises.

Asplenium has an average growth rate. It is a perennial and can live 4-10 years in indoor conditions. There is nothing difficult in caring for such a fern, so it is perfect for novice florists.

Brief description of cultivation


  1. Temperature conditions . This fern loves warmth. However, in winter, he needs to provide cool content (from 12 to 14 degrees).
  2. Air humidity . Requires high humidity. In this regard, the bush must be systematically moistened from a spray bottle, and it is also recommended to put it on a deep pallet filled with wet expanded clay.
  3. Illumination . The plant thrives best in shade, a northern windowsill is perfect. At the same time, you cannot put it in an excessively sunny place.
  4. Watering . In the spring and summer period, watering should be regular and frequent (2 or 3 times a week). Keep the potting soil moist at all times. In winter, watering should be reduced to once every 7 days.
  5. Land mixture . It must be loose and breathable well. You can use a ready-made commercial soil mixture for ferns. To prepare the substrate with your own hands, combine leafy and sod soil, peat, and sand in equal parts.
  6. Fertilizer . They are fed with a purchased mineral complex while using ½ part of the dosage recommended by the manufacturer.
  7. Transplant . The root system grows quite quickly, so the fern needs annual replanting. In this case, each time you need to replace the pot with a larger one.
  8. Reproduction . Most often propagated by dividing the rhizome or bush.
  9. Features of care . In order for the plant to feel comfortable in indoor conditions, it is impossible to allow direct sunlight to hit its foliage, and it is also necessary to maintain high humidity in the room.

Home care for Asplenium


It is quite simple to care for a room Asplenium. But if you want the plant to be spectacular and thick, then try to provide it with the most favorable conditions. Remember to water it regularly and often, and choose a shaded spot for it. However, make sure that no liquid stagnation is observed in the substrate, as this can lead to rot on the root system.


Asplenium, like most ferns, does not form flowers. Over time, spores appear on the seamy surface of the leaf plates, from which, if desired, new ferns can be grown. At the same time, the disputes do not represent any decorative value.



The plant has an unusual ability – it can adapt to different air temperatures, typical for a particular room. However, sharp changes in temperature should not be allowed, as this can harm the bush. At a temperature of 12-22 degrees, the plant feels quite comfortable.

Air humidity

Requires high humidity. In spring and summer, foliage must be moistened with a spray bottle at least once every 2 or 3 days. If this is not done, then specks of brown or yellow hue may form on the surface of the leaf plates. The plant responds well to regular warm showers.

To maintain a high level of humidity, experienced florists recommend taking a deep pallet and filling it with wet expanded clay. A pot is placed on top. Do not forget to regularly moisten expanded clay.



An overly sunny place is not suitable for indoor Asplenium. The fact is that in natural conditions, the plant is hidden from the scorching rays of the sun by foliage and branches of trees, as well as larger plants.

The plant will feel best in the northwest or north window. You can choose another place that will be reliably protected from the direct rays of the sun.


In order for the fern to grow well, it needs regular, abundant watering. To do this, use soft water, which must settle for several days.

After some time after watering, be sure to drain the water from the sump. In winter, the plant is watered once a week, while do not allow the clod of earth in the pot to dry out completely.

Pot selection


The root system of the bush grows very quickly. In this regard, it is necessary to choose a fairly capacious container for the fern, but it should not be too large. If the pot is too voluminous, then the Asplenium will begin to actively grow roots to the detriment of the development and growth of foliage. In addition, in a very large pot, there is a high probability of rot on the root system.

Soil mixture

For home Asplenium, a loose, slightly acidic, and well-drained soil mixture is best suited. If desired, a ready-made fern potting soil can be purchased at the flower shop. You can also make the substrate with your own hands: combine sand, peat, leafy, and soddy soil (1: 1: 1: 1).


The plant needs regular feeding. For this, a mineral complex fertilizer is suitable, in which potassium must be present. Topdressing is combined with watering the plant and is carried out once every 4 weeks. In this case, the dosage of fertilizer must be reduced by half from the recommended on the package.

Asplenium transplant


The root system of the Asplenium grows rather quickly. If the bush is not transplanted in time, then you can see how the roots grow into the drainage holes or appear on the surface of the substrate. This suggests that the plant needs to be transplanted into a new, larger pot as soon as possible. An urgent transplant is also necessary if the fern grows very slowly or does not want to grow at all.

While the bush is young, it is transplanted every year and done in autumn or spring. An older Asplenium is subjected to this procedure once every 2 or 3 years.



The foliage of this plant is cut not only to make it look neater but also to improve the growth and development of young leaf plates. The fact is that excessively large foliage interferes with the development of young shoots. The foliage is cut once every couple of years, for this, they use a pruner or a very sharp knife. The cut should be done directly at the base of the bush.

Dormant period

The beginning of the dormant period in Asplenium falls on the last days of November, while it lasts until the first days of March. At this time, the bush is removed in a cool place, which should be located away from working heating appliances. Particular attention should be paid to watering during the dormant period. It is carried out, as a rule, 1 time in 7 days (or less often), but make sure that the lump of earth in the pot does not dry out completely.

Going on vacation

An indoor Asplenium can survive one to two weeks without water. If you will be away from home for a short time, then before you leave, water the bush abundantly, after which it is placed on a pallet filled with wet brick chips or expanded clay. The pot must be placed so that its bottom does not come into contact with the liquid.

Reproduction methods

Growing Asplenium from spores


Like any other ferns, Asplenium instead of seeds, spores form on the seamy surface of the leaf plates. If necessary, they can be removed from the bush and sown. To do this, use a bowl filled with a moist soil mixture. Spores are simply spread over the surface of the substrate, and they cannot be sprinkled on top. Be sure to cover the bowl with transparent glass or film. Provide the crops with daily ventilation, and do not forget to moisten them in time with warm water from a sprayer.

The first seedlings should appear approximately 6 weeks after sowing. After the seedlings reach 20-25 mm in length, they must be thinned out, while the most powerful shoots should remain. After the seedlings grow up, they must be cut into individual pots. This fern breeding method is quite long, while young plants need to be constantly monitored. In this regard, it is not very popular with flower growers.

Dividing the bush


For reproduction, plants use another easier method – dividing the bush. An adult bush with many layering is suitable for this. Remove it from the pot and carefully divide it into pieces. Please note that each division must have at least 7-10 growth points.

Excessively small divisions do not take root well and may die. In this regard, the division should be strong enough and there should be a sufficient number of growth points on it for normal rooting. The plank should be planted in the substrate to a depth of 20 to 25 mm. Do not deepen the cut too much, because because of this, it may never start growing and will die after a while.

Possible problems


If the houseplant is not properly looked after, then this can lead to the following problems:

  1. The foliage turns brown . The plant feels a lack of moisture. Water is more often.
  2. Drying of the tips of the leaf plates . Excessively low air humidity. Moisten foliage with a sprayer more frequently.
  3. The foliage has lost its turgor, but does not dry out . The room is very cold.
  4. The foliage becomes faded and loses its shine . Move the fern to an area with less intense lighting.
  5. Brown specks appear on the leaf plates . The plant is too hot. Move it to a cooler place, away from working heaters.
  6. The foliage turns yellow and brown spots form on it . This is a sign of the onset of sporulation.
  7. Brown dots form on the seamy surface of the sheet plates . An excessively sunny place was chosen for the plant.
  8. Pests . Most often, scabies and spider mites settle on the Asplenium.

Types of Asplenium with a photo

Asplenium nidus


This type of Asplenium is most popular in indoor culture. Quite wide leaf plates in length can reach about 150 cm. The powerful root system consists of many tangled roots. The plant looks more decorative due to the fact that a strip of purple hue is located in the middle of each leaf plate.

Asplenium viviparum


A rather narrow rosette consists of large wavy leaf plates painted in a greenish tint. Each of the shoots has a large number of narrow small segments that reach no more than 10 mm in length. In an adult bush, brood buds are formed on the edge of the leaf plates.

Asplenium bulbiferum


This plant is highly decorative. Longleaf plates (about 1.2 m) hang dramatically along the edges of the pot, resulting in a beautiful thick head. The segments of the leaf plates are rather wide. A newly planted bush takes root very quickly. The species belongs to fast-growing plants.

Asplenium dimorphum


This type is very popular with flower growers. It is used to decorate shaded rooms and is also cultivated in conservatories and greenhouses. Dissected large leaf plates reach about 100 cm in length.

Beneficial features

Asplenium is able to decorate any room, moreover, it is a useful plant. The large green foliage of the fern absorbs harmful impurities in the air, thereby purifying it. It is able to absorb both chemical compounds and gases that can harm a person.
