Tiger Water Lily or Nymphea lotus (Nymphaea lotus) – aquarium plant Nymphaeaceae family.
According to some sources, the birthplace tiger lilies West Africa, but authenticity is not established.
Nymphea lotus It is the most beautiful among lily pads and valuable not only by the magnificence of the colors, but also by the specific color of the underwater leaves: they are covered with a large number of brown spots. Floating leaves are painted olive or green.
Only two plant forms are cultivated: green and red. The second has a more intense color. For breeding at home need a wide aquarium, water in which does not rise above the mark of 45 cm.
Tiger Water Lily – a seasonal plant, in winter its growth slows down, floating leaves are almost not formed.
Tiger Water Lily feels comfortable in a tropical aquarium with a water temperature of about 24-28 ° C. In water with lower temperatures (below 22 ° C) water lily slows growth and stops flowering. Water parameters are also important because they affect the growth and development of the plant.
Water with the following parameters will be optimal: hardness – not more than 4 °, acidity – 6-6.8. In water other than favorable, the plant begins to bush, stops releasing floating leaves, and underwater leaves become much smaller and does not bloom.
It does not need regular water changes, it feels very good in the old, saturated with humic acids.
Nymphea lotus needs bright light, direct sunlight is especially useful. With a lack of lighting the color of the plant dims, this is especially true for the red-leafed form of the plant, the cuttings of underwater leaves are lengthened, and the bush as a whole loses its shape. The special fitolamps that are used in greenhouses are best suited as light sources.
You can also use fluorescent lamps, but incandescent lamps are recommended to be used only as an additional source of red-orange rays of the spectrum. To create the necessary illumination lighting will require a powerful lamp. But to avoid leaf burns or water overheating in aquarium Illuminators must be placed at a sufficient height.
To create favorable conditions for flowering and breeding tiger lilies the power of fluorescent lamps is calculated per displacement (not less than 0.5 W / l). The duration of daylight hours is at least 14 hours.
Root system nymphs big enough, but its rhizomes are gentle. On this basis, it is better to use a mixture based on small pebbles as a soil.
Also, the mixture should include clay, peat and charcoal. In pools or large aquariums better to grow tiger water lily in separate containers or pots. In this case, the soil in the pot is laid out as follows: first, small pebbles and sand are placed on the bottom, then a layer of soil.
The soil consists of a mixture of humus (1 part), coarse sand (1 part) and small pebbles (2 parts). A two-thirds pot filled with such a mixture is planted. water lily, and then the pot is complemented with small pebbles and sand. Apply this primer in aquarium It is impossible, as the chemical composition of water will change.
Periodically it is necessary to produce additional fertilizing with mineral fertilizers with the calculation of 1.5-2 g per 100 liters of water.
Breeds tiger water lily seeds or vegetative way. In the summer-autumn period, the plant blooms under favorable conditions.
These flowers can be artificially pollinated with a soft brush. After ripening, seeds are sown in separate bowls filled with sand and water. About a week later, the plant will release 2-3 leaves, then the plant is diving and transplanted into a large container.
After forming 4-5 large leaves water lily transferred to aquarium. In water whose hardness exceeds 6 °, tiger lilies formed basal otvodki in large quantities.
A thick bush is formed that needs periodic thinning, otherwise the plant becomes weak and incapable of normal development. In water with a hardness below 4 °, basal processes are formed after the flowering period.
During wintering, after seed formation and flowering, water lilies a state of rest comes and during this period the water temperature is reduced to 20-22 ° C. After wintering, the plant contained in aquarium, useful to transplant.
For plants contained in individual pots, this is not necessary. In the vegetative propagation method, the daughter plants are transferred to a separate pot with nutrient primer.
