The most common aquarium plant among the large Echinodorus family is undoubtedly the chic, large and bright green Echinodorus Bleher, which is often called the “yarrow”, the taxonomic name Echinodorus bleheri. Its bushes grow in large aquariums up to half a meter in height, and large lanceolate wide leaves, with good care, delight amateur aquarists with their lush greenery.
In 1970, the Czech hydrobotanic Karel Ratai made a detailed description of 47 species of Echinodorus growing in Central America, the Antilles and Argentina. It was then that the scientist identified the species Ekhineodorus Bleher, as one of the large-leafed and unpretentious in content, recommended it for aquariums. Since then, Echinodorus Bleher, thanks to the remarkable decorative data, has become popular and loved among aquarists.
Juicy green and lanceolate, large and wide leaves of Echinodorus Bleher form a strong dense bush. In one bush, it can grow up to 30 with a juicy shade of salad of large leaves. The width of the leaves of Echinodorus Bleher reaches 8 cm. Under favorable environmental conditions, the plant blooms profusely, but this phenomenon is rarely observed in home aquariums. The large-leaf Echinodorus Bleher absorbs organic matter well from the aquarium water and saturates the water with oxygen. With good lighting from its leaves, small air bubbles rising to the edge of the water are clearly visible.
This plant propagates rapidly in a vegetative way, namely by dividing a powerful rhizome. Carefully with a sharp knife, you can cut off part of the rhizome with the kidney that appears on it and immediately plant it on the prepared spot. An adult bush at a year and a half age produces long arrows, on which young plants form over time.
The arrows should be fixed with studs or pebbles, and as soon as 3-5 plants appear on young plants, carefully separate them from the fragile arrow and transfer to the right place. If several plants are formed, in order to preserve all the shoots, it is necessary to plant them in a separate tank. It will not be superfluous to remove old and weakened leaves from the mother plant.
Echinodorus Bleher should be planted in a large aquarium 100-150 liters in the center or at the back wall. Its dense bush with wide leaves obscures all the plants that are nearby, so there is no need to experiment, and plant other plants under its leaves, they will not survive.
Optimum temperatures for growing Echinodorus Bleher are +20aboutC - +28aboutC. But every year for 1-2 months you should lower the temperature to +20aboutC - +22aboutC, simulating the presence of winter months, similar to growth in natural conditions. In a general aquarium, it is sometimes difficult to do this, plants are simply planted for this period.
Echinodorus Bleher prefers neutral water or slightly alkaline, but it can grow for a long time in water with high acidity pH 5.5. The stiffness of aquarium water is not critical for growing this plant, it will grow well in water of any hardness. You should also replace up to 1/5 of the volume of aquarium water up to three times a month.
Soil for Echinodorus Bleher should be prepared from finely chopped gravel and put under the roots clumps of clay mixed with boiled peat. The plant is completely undemanding to the soil, grows well on the soil of any silty.
It is possible to illuminate this type of Echinodorus strongly, but it withstands well and shading. If the tank of the aquarium is near the window, then the plant will have enough daylight. The optimal lighting intensity for Echinodorus Bleher ranges from 0.3 W / l with fluorescent lamps to 0.6 W / l for conventional incandescent lamps.
