Cryptocoryne Petch (Cryptocoryne petchii)

Kryptokorina Petch (Cryptocoryne petchii) is an aquarium plant of the Cryptocoryne genus (Cryptocoryne) of the aroid family (Araceae).

Homeland Petz’s cryptocorynes is the island of Sri Lanka.

Kryptokorina Petch It is a loose rosette of brown-olive leaves. Bottom sheet plate is painted in red-purple color and has transverse strokes. In height, the plant reaches 12-15 cm, very rarely grows up to 20 cm.

handsomely Kryptokorina Petch looks in the foreground aquarium. The plant develops evenly throughout the year.

However, Petzp’s cryptocoryn is very demanding on the conditions of detention and therefore not very common among aquarists.

Contain Kryptokorinu Petch possible only in tropical aquarium, in which the water temperature below 24 ° does not fall, because at a temperature below the specified growth of the plant stops. Kryptokorina Petch can grow in both soft and more hard water.

Although very sensitive to fluctuations in pH in water, the hardness of which is below 6 ?. In an acidic environment, cryptocorynous disease develops and the plant sheds leaves. It is recommended to stabilize the weak alkaline reaction by adding a quarter or half teaspoon of sodium bicarbonate (baking soda) with each water change.

It is not necessary to replace the water for the plant, but plant content in relatively hard water, it can be done 2-3 times a month without consequences. Kryptokorina Petch to lighting not demanding. He feels satisfactory in the shadow of other, larger neighbors.

As the illuminators used incandescent lamps, fluorescent lamps, or a combination thereof. To create the optimum lighting, lamps with the power of: for fluorescent lamps – 0.4 W / l and for incandescent lamps – 1.2 W are used.

Also solar diffused light is useful to a plant. As a rule, daylight falling out of a window in combination with artificial lighting is not enough to improve the growth rates of Pöttsch cryptocore. But it is necessary to ensure that the leaves of the plant are not covered with algae, which often occurs with an excess of light, especially natural.

The average duration of daylight hours is about 12 hours, but it can vary depending on the intensity of the light. Soil for growth Petz’s cryptocorynes should be heavily or moderately silted and quite nutritious. Coarse sand or small pebbles is perfectly suited as a substrate.

In the new soil you need to add clay. The plant does not need additional feeding, and natural siltation is sufficient. For normal development of the root system, the soil is laid in the aquarium with a layer about 5 cm thick.

It is necessary to periodically make mineral fertilizers in water, as well as salts of bivalent iron. Without the latter, the leaves of the plant will not acquire such a bright saturated color.

Cryptocorina Petch it can also be kept in a paludarium at a temperature not lower than 24 ° C and bright light, as well as in a nutrient soil. Such conditions are more acceptable for reproduction and growth. But, unfortunately, the decorative properties of the plant in such conditions are lost: the color of its leaves becomes brown, the strokes disappear and the intensity of the color of the underside weakens.

The plant is transferred from the aquarium to the paludarium, gradually reducing the water level in the tank. The transition to the air environment of the cryptocoryn Petch transfers more easily than back.

In the second case, the plant for a long time adapts to the aquatic environment.

In artificial conditions Kryptokorina Petch multiplies only vegetative way. On the creeping root of the plant, the stepchildren are formed, which can be separated after the formation of 4-5 leaflets on them.

Since in soft ground Kryptokorina Petch does not form dense thickets, stepchildren are separated easily.
