Derbennikov family. Homeland - South America. In nature, there are about 200 species of Blehnum.


Blechnum humpbacked Blechnum gibbum - in nature it is a large, palm-like, plant with vays reaching 1.5 m in length. The stem of the fern is a modified rhizome; in old plants in indoor conditions it reaches a height of about 50 cm, covered with brown scales. Vai it is once pinnate-dissected, about 50-60 cm long, light green in color. Sporangia on the underside of the leaf, closer to the edge of the segments.

At home, blehnum, of course, is smaller in size - old specimens are about 100 cm wide and the same height. But this fern is a real home decoration.

How to grow Blehnum

Temperature: Blehnum is a fern of warm rooms. In summer, it is kept at normal temperatures, optimally up to 28 ° C, in the heat of the dry air, the blehnum can dry out. In winter, it is desirable to lower the temperature to 18-20 ° C, at least 16 ° C. Be sure to protect the fern from the hot air of the radiators.

When ventilating, especially in winter, move the plant away from the cold air flow, including the air conditioner.

Lighting: The place should be light enough, but shaded from direct sunlight - bright diffused light or light partial shade. Blehnum grows well in the north and northwest window, well on the east and southeast. You can place the pot near the south window under the shade of a tulle curtain or blinds. It will be hot on the western windowsill in summer. But in winter, from about October to the end of January, the direct sun will not harm the ferns at all.


Watering: Only with warm, settled water that does not contain lime. Blehnum is watered abundantly in spring and summer, well wetting the earthen lump, but only after the top layer of the earth has dried. In winter, watering is moderate, the soil should not dry out completely, to a dusty state.

Fertilizer: In summer, liquid fertilizer for indoor ornamental deciduous plants every two weeks. Blehnum is very sensitive to excess fertilizers, so the dose should be taken 2 times less than the manufacturer's recommended dose. Never fertilize after transplanting for at least 1.5 months.

Humidity: Like many ferns, Blehnum loves humid air, but spraying can ruin the leaves. Therefore, the pots with plants are placed on pallets with wet expanded clay. The batteries are hung with a damp cloth in winter.

Transplant: Transplant is carried out in the spring, when the roots fill the entire pot. The soil should have a slightly acidic reaction. Soil - 2 parts of leafy land, 1 part of peat, 1 part of humus earth and 1 part of sand. You can add chopped pine bark to the substrate. Good drainage at the bottom of the pot and drainage holes are a must.

Reproduction: Mainly by dividing the bush or by spores that form on the back of the leaves. When propagating by dividing the bush, during transplantation, you need to cut off 2-3 leaves with a small part of rhizomes from the edge of the bush with a sharp knife. Place the cut in a pot that is about 2 cm larger than the root ball. Cover with earth and water. The fern grows slowly after transplantation - at first the root system is gaining strength, new roots grow. A noticeable growth can be only one month after transplantation. Do not repot or divide blehnum bushes and other ferns during hot summer months.
