Video: Polyseminated Hygrophila (Hygrophila Polysperma)
Hygrophila polysperma (Dwarf hygrophila, Dwarf hygro, Miramar weed) - herbaceous aquatic plant common in the waters of South East Asia. The root system is poorly developed, the roots are white, filiform.
The stem is smooth, elongated in length, the leaves are oval, light green, elongated, located in pairs opposite each other; adjacent pairs are mutually perpendicular. The plant is very unpretentious, it can grow for a long time in low light, without rooting. It can be used as a spawning substrate for fish.
When kept in an aquarium, the optimum temperature is 24-28 ° C. At temperatures below 22 ° C, growth slows down significantly. Water needs slightly acidic and soft (hardness no more than 8 °). Mineral fertilization is only required if there are a large number of plants in the aquarium with a weekly water change. It requires bright diffused lighting with a day length of at least 12 hours. However, the hygrophila is able to withstand prolonged shading. In case of insufficient light, the stem of the plant stretches out, and the leaves become small. A slightly silted soil of coarse sand or small pebbles is required. In plants floating in the water column without rooting, the leaves become small, and their growth is greatly slowed down.
Propagated by ground shoots and cuttings, which can be immediately planted in the ground. The temperature of the content is 24-28 ° C. At temperatures below 22 ° C, growth is greatly slowed down. Water needs slightly acidic and soft. The plant is planted in soil consisting of a mixture of peat, leafy earth, sand and clay. It requires bright diffused lighting with a day length of at least 12 hours. In case of insufficient light, the stem of the plant stretches out, and the leaves become small.
In the aquarium, they are used as a background vegetation or planted in small groups in the middle. The usual form of polyseed hygrophilia has light green leaves of the same shape. Leaves take on a shade of pink or orange as they get closer to the light source.
The poly-seeded hygrophila is a marsh plant and can be grown in a paludarium or humid greenhouse. In addition to this hygrophil, the aquarium cultivates the guiana hygrophila (Hygrophila guianensis) with narrow-lanceolate green leaves, which, when the shoot reaches the surface, blooms with large white flowers, and the willow hygrophila (Hygrophila salicifolia), whose leaves resemble willow leaves. Growing conditions for all hygrophils are similar.
