It's best to place it in an open area where it can receive the maximum amount of light possible. This plant can tolerate some shade, but it will grow much slower in these conditions.
Temperature Requirements
The ideal temperature range for Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp. is between 21°C to 30°C (70°F - 85°F). They can tolerate slightly lower or higher temperatures, but growth may be stunted. It's important to maintain a consistent temperature around the plant. Drastic temperature changes can harm the plant's growth.
Soil Requirements
The plant prefers warm, freshwater environments with nutrient-rich mud and silt sediments. It can tolerate a wide range of soil types, such as clay, loamy, and sandy soils. However, for optimal growth, the soil should have a pH range between 6.5 and 7.5. This plant also requires adequate oxygen in the soil, so avoid planting it in areas with high water saturation or stagnant water.
Cultivation methods
Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp. is a perennial aquatic plant that grows best when planted in still water with a minimum temperature of 21°C. The plant requires full sun exposure but can also thrive in partially shaded areas. It's recommended to plant the Nymphaea lotus L. var. dentata in pots, which can be sunk into the water garden.
Watering needs
This plant requires a considerable amount of water, and it's essential to keep the soil wet at all times. The water in the pond should be deep enough to cover the pot and maintain the needed temperature.
Fertilization
The Nymphaea lotus L. var. dentata has a small root system that does not store nutrients, so it's important to fertilize it regularly. One way to fertilize is by using slow-release fertilizers that will ensure a continuous nutrient supply throughout the growing season. It is advisable to avoid overfertilization as it can lead to the development of algae or may damage the plant.
Pruning
Pruning is fundamental to keep the Nymphaea lotus L. var. dentata healthy and sustained. Dead flowers should be removed from the plant frequently to avoid the accumulation of dead material within the pot. The leaves and stems should be regularly trimmed to maintain the desired size and shape of the plant. It is best to use sharp pruning shears and clippers to avoid harming the plant. Pruning should be done when the plant is dormant or in early spring when it starts to grow.
Propagation of Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp.
Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp. is a perennial aquatic plant commonly propagated for its beautiful flowers and decorative leaves. The propagation of this plant can be done through several methods namely:
Propagation through Seeds
Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp. can be propagated by seeds, which are collected from the parent plant. The seeds should be sown in pots or containers filled with a suitable growing medium. The medium should be kept moist, and the pots should be placed in a warm and sunny area. The seedlings will start to emerge within a few weeks. Once the plants are established and have developed roots, they can be transplanted into a pond or container garden.
Propagation through Rhizomes
Rhizomes are horizontal underground stems that produce new shoots and roots. Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp. can be propagated through rhizomes, which are divided from the parent plant. The rhizomes should be cut into smaller sections, each containing a healthy shoot and root system. The sections should be planted in pots or containers filled with a suitable growing medium. The medium should be kept moist, and the pots should be placed in a warm and sunny area. The plants will start to develop new shoots and roots within a few weeks. Once the plants are established, they can be transplanted into a pond or container garden.
Propagation through Stem Cuttings
Stem cuttings can also be used to propagate Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp. Stem cuttings should be taken from the parent plant, and each cutting should contain at least one node. The cuttings should be planted in pots or containers filled with a suitable growing medium. The medium should be kept moist, and the pots should be placed in a warm and sunny area. The cuttings will start to develop roots within a few weeks. Once the plants are established, they can be transplanted into a pond or container garden.
In conclusion, Nymphaea lotus L. var. dentata (Schumach. & Thonn.) Casp. can be propagated through seeds, rhizomes, and stem cuttings. Propagation via these methods is relatively easy and can be done by home gardeners interested in growing this aquatic plant for aesthetic purposes.
