Ferns

Ferns - a very special group of plants, the representatives of which can be called "living fossils" flora.However, not only the antiquity of origin can be considered as something separate and distinct from all other indoor plants: in ferns another not only anatomy, but physiology (to learn the ropes of their physiology is not necessary, but remember that they are different, even at this level, you mustto know that ferns do not look like the rest of house plants!).Even the reproduction of their quite different - Spore;"Fern flower" exist only in legends, instead of flowers on the underside of the leaves formed a special education -sporangii, shape and location of which are important systematic features.In ferns leaves with a special internal structure called vayyami.They look very diverse.

Not surprisingly, the requirements for their content also differs significantly from the requirements for the content of other houseplants.

requirement to moisture: Most ferns are very hygrophilous, they require heavy

watering, do not tolerate drying earthen clod, daily spraying is necessary, in hot weather - twice a day.Water for irrigation and spray should be soft.

Temperature: Most species can not tolerate the temperature drops below 13 ° C.Sharp temperature fluctuations are harmful.He does not tolerate drafts.

Light regime: very shade-tolerant, direct sunlight can not tolerate.Can grow at an artificial light.Optimal northern exposure.

requirement to the ground: for the young plants the optimum ground from peat, leaf and humus land with sand in a ratio of 2: 2: 1: 1;Adult specimens turf ground is added, then the ratio is as follows: 3: 3: 1: 1: 2.For derived from spores prothallia used the third option zemlesmesi: ground sheet, peat, sphagnum-moss pureed and river sand in equal parts.The substrate for sowing spores (easiest option) - peat and leaf ground with sand in a ratio of 2: 1: 1.For epiphytes need to increase the proportion of peat.

In the period of active growth - alternating feeding solutions of mineral and organic fertilizers.

Reproduction: dividing rhizomes, brood buds (in "live-bearing" types), which can break off during the formation together with a piece of fronds and rooting in the loose substrate;spores.For sowing spores using shallow containers such as Petri dishes.The above substrate is compacted and moistened with boiling water, after cooling seeded spores, moistened with a weak solution of potassium permanganate or hinozola and cover glass.After formation prothallia moved past a large capacity low substrate with another embodiment.

Features for the transplant to be removed spoiled roots.
