Ludwig Creeping (Ludwigia repens or Ludwigia natans)

Ludwig Creeping (Ludwigia repens or Ludwigia natans) – aquarium plant of the family Onicriaceae (Onagraceae).

Ludwig Creeping in natural conditions found in silted marshy water bodies of Central and North America.

Due to its unpretentiousness and gorgeous appearance creeping people became the most popular and common aquarium plant. Her variegated openwork thickets neatly scattered around the perimeter aquarium, give it extraordinary decorativeness, visual volume, relief and depth.

Under good conditions plant content takes part in the circulation of substances in a closed pond: it is well saturated with water aquarium life-giving oxygen and cleans it, feeds on organic residues, and also serves as some aquarium fish as feed. Thickets creeping people They are an excellent refuge for fry and weakened fish, as well as a favorite place where many species of fish spawn.

Ludwig Creeping – It is a marsh plant that takes root in the ground. The root system of the plant is poorly developed, fibrous, formed by the roots that develop on the lower parts of the shoot. Stems creeping people herbaceous, intensely branched, relatively low and grow to 30-40 cm, and with regular feeding and good aquarium lighting can reach a length of up to 50-60 cm.

In the water column, they are erect, but rising to the water surface, they are transformed into super-creeping ones. The leaves on the shoots are located opposite, and each pair of leaves is perpendicular to the previous one.

Leaves creeping people have a different stem length – the leaf the younger, the shorter its leaf stem. The youngest leaves on the top of the shoot are sessile and generally do not have a petiole.

This arrangement of leaves forms a flat outlet. Creeping Ludwig has very peculiar colored glossy leaves: on top, the color of the leaf blade can vary from olive green to deep dark green, and from the bottom the leaves are green or wine red. Depending on the location of the leaves relative to the water column, their size also depends, which varies from 2.0 – 3.0 in length and 0.5 – 1.5 in width, as well as the shape of the leaf blade, which can be narrow oval in thicker than water and almost round on the water surface.

When creating favorable conditions creeping people It blooms, throwing a bright, noticeable flower with a diameter up to 0.5 cm in the axils of the aerial leaves. In addition to 4 green sepals, like in most species of people, the creeping flower of Ludvigiya has four bright yellow petals, which makes it particularly beautiful.

Ludwig Creeping feels great in both moderately warm and tropical aquariums, it is not a matter of hardness of water, but for optimal growth and development it needs water temperature just below 26 ° С and medium illumination aquarium. A plant can tolerate a short-term increase in temperature in an aquarium above 26 ° C, but prolonged exposure to elevated water temperature on the plant leads to its death. Does not love creeping people, unlike other types of people, and lowering the water temperature below 16 ° C, so the water in aquarium, where it grows, it should be between 18 and 26 ° C.

Although the plant is rather unpretentious, but in aquariums, where the hardness of the water is less than 5-6 ° C and a neutral or weakly acidic environment, the growth and development of creeping lyudvigii is much more intense and better. Ludwig Creeping needs good, at least 12 hours a day, illumination: the light should be bright and diffused, without direct rays falling on the leaves and stems. With a stronger light, the color of the plant becomes saturated and bright, however, when it is oversupplied on the stems and leaves of the plant, a bloom of filamentous or unicellular algae may appear, which negatively affects the well-being of creeping people and may lead to its death.

However, in low light, the plant slows down its growth, a beautiful maroon tint on the lower part of the leaf becomes pale. Aquarium, where is growing creeping people it is desirable to equip fitolamps with an improved spectrum of illumination, then the plant begins to actively develop and becomes extremely beautiful rich color of leaves.

With a weak light or the absence of lamps with special lighting, an extraordinarily beautiful plant can be admired when the creeping shoots of Ludwigia grow stronger and grow to the surface of the water. Having appeared in conditions where there is much more light than in water, the plant begins to look better right before the eyes: the leaf blades become intensely bright in color, and the stem begins to branch intensively. Ludwig Creeping has a poorly developed root system, therefore, needs nutrient fine-grained soil.

In aquariums with old soil, it is enough for medium-sized soil, but if aquarium put a new soil, then it must be made dressing. Ludwig Creeping responds well to iron supplements, as well as supplements in the form of clay balls.

The plant feels comfortable in the soil of small gravel or sand poured to the bottom aquarium 3-4 mm layer. A larger soil is not suitable, since large particles of soil can cut weak and tender roots. If the plant begins to lose the lower leaves, then it is recommended to remove it from the ground and carefully examine the roots – most likely the root system of such a plant is damaged and the plant needs to remove rotting roots.

When the roots of the plant are cleaned, it must be planted in a new place. Ludwig Creeping can live in aquariums of any capacity, where the water level is relatively low.

The plant loves clean, enriched with oxygen and carbon dioxide water, therefore it is recommended in aquarium Once a week, do a substitution of 1/3 of the water. To achieve a decorative effect, crawling Ludwigia is planted in free groups around the back and side walls, sometimes in small groups in the middle part of the aquarium.

Under optimal conditions of maintenance, the plant develops very quickly, forming branched and long shoots that can grow up to 4 cm over a week, so crawling lyudvigiy needs to be regularly cut and remove unnecessary shoots.

Ludwig Creeping multiplies grafting. It is necessary to choose cuttings for reproduction with a clearly defined growth point, then the cutting will quickly take root in a new place.

The best parts for breeding are the upper parts of the stem, the length of which should not be less than 10 – 13 cm. The stalk is planted in nutrient fine-grained soil, and the cut off tip of the “mother” plant gives a lot of new side shoots.
