Echinodorus cordifolius

Family Alismataceae – Chastukhovye. Central America is the homeland.

A unique plant with exquisitely beautiful hard leaves speckled with gold. can grow to notable proportions. The plant in the aquarium is usually only 20 to 30 cm tall during its first year; later, it develops above-water and floating leaves and grows to a height of 80 cm. It ought to be maintained in a humid greenhouse or a deep aquarium.

The water temperature is preferably within 22 – 26 ° C, however, Echinodorus tolerates a significant (up to 12 ° C) decrease in temperature for 2-3 weeks very well. At water temperatures up to 10 °C, it can shed all its leaves. However, the rhizome remains in the soil, which resumes growth under favorable conditions. The plant tolerates a temperature increase of more than 28 °C as well as a decrease in temperature, but needs a rest at a temperature of 18 – 20 °C twice a year for 1-1.5 months. The plant does not like acidic, very soft water. Optimal conditions for growth are water with a hardness of 8-16 ° with a pH greater than 6.8.

Echinodorus cordifolia needs to be kept in a brightly lit aquarium. The plant does not take well to shadowing. Use 0.4 to 0.5 W of LB type fluorescent lamps for lighting, one lamp for every liter of water. Adding more lighting using incandescent lamps is a good idea. Using only incandescent lights for lighting is very energy-intensive and not recommended for aquariums kept indoors.

A short day (about eight hours) combined with bright lighting enables the plant to store only submerged leaves for an extended period of time. When the day lengthens to eleven or twelve hours, Echinodorus starts to develop aerial leaves and flowers.

There should be a moderate to slight siltation of the soil. Plant roots are susceptible to rotting in extremely humus-rich soil. It is very helpful to add charcoal and clay under the roots to prevent this. Any type of substrate will do, ranging from big pebbles to coarse sand.

In an aquarium, Echinodorus cordifolia typically reproduces vegetatively. Daughter plants are produced on the peduncle following flowering. The flower stalk in this instance needs to be submerged in water. The daughter plants can be separated from the mother bush and moved into the common soil once several leaves and root buds have formed. Even in unfavorable conditions, they typically start growing and developing well very quickly.

You can obtain plant seeds in a humid greenhouse, but germination rates are typically low. When they are mature enough, they should be planted in shallow bowls of water-filled sand under bright enough lighting.

Echinodorus grows much better, reaches a much larger size, and blooms earlier in a paludarium than it does in an aquarium. You can grow it in a greenhouse using garden soil supplemented with peat and sand. Maintaining an air temperature between 24 and 28 °C is preferable.
