Light Requirements
Nymphaea fraterna Mill. & Standl. requires a significant amount of light to grow. It is recommended to grow them in full sunlight or partially shaded areas. A minimum of 6 hours of sunlight is essential on a daily basis to ensure healthy growth.
Temperature Requirements
The optimal temperature range for Nymphaea fraterna Mill. & Standl. growth is between 20-30°C. The temperature should not drop below 10°C as it can hinder the growth of the plant, and if the temperature exceeds 35°C, it can damage the plant. Maintaining the optimum temperature level is crucial for the survival of the plant.
Soil Requirements
Nymphaea fraterna Mill. & Standl. prefer clay and loamy soils that are rich in organic matter. The pH of the soil should be between 6.0–7.5. A mud substrate is recommended for optimum growth. However, if there is no mud substrate, aquatic potting soil is suitable. It is important to ensure that the soil is not too compact or hard, and that there is adequate drainage to avoid waterlogging of the soil and prevent root rot.
Cultivation methods
The Nymphaea fraterna Mill. & Standl. plant, commonly known as the Texas water-lily, is a semi-tropical water lily that thrives in warm climates. To cultivate this plant, one needs to plant it in a container filled with soil, and then submerge it in water. It grows well in shallow water (1-2 feet deep) in either a pond, a small water feature, or a container garden. The soil should contain clay, loam, and organic matter. Also, ensure that the container has enough space to accommodate the plant's root system, which can spread up to 3 feet.
Watering needs
Since the Nymphaea fraterna Mill. & Standl. plant is aquatic, it requires plenty of water to thrive. It's essential to keep the container or pond water fresh and clear. Rainwater is the best water source to use as it is pure and free of chemicals. If using tap water, allow it to sit for at least 24 hours before using it. During hot, dry periods, water the plant daily to prevent it from drying up or getting burned by the sunlight.
Fertilization
The Nymphaea fraterna Mill. & Standl. plant requires fertilizer to grow and thrive properly. Use a slow-release or granular fertilizer specifically designed for aquatic plants. Fertilize the plants once a month during the growing season (usually from spring to fall). Dissolve the fertilizer in water and pour it over the plant's leaves and the water's surface level. Avoid using too much fertilizer as it can cause algae formation, which can be detrimental to the plant's growth.
Pruning
Pruning is an essential aspect of Nymphaea fraterna Mill. & Standl. plant care. Remove any yellowing or dead leaves to prevent the plant from rotting. Cut the leaves and stems back to the plant's crown or base using sharp and clean pruning shears. The crown is where the plant's leaves and roots meet. Also, remove any stems or leaves that are growing out of bounds or blocking the pond or water feature's view. Regular pruning ensures that the plant remains vibrant and healthy.
Propagation of Nymphaea fraterna Mill. & Standl.
Nymphaea fraterna Mill. & Standl., commonly known as the Sierra Madre yellow water lily, is a beautiful aquatic plant that can be propagated through several methods. Here are some of the most common propagation techniques:
Propagation by Seeds
The Nymphaea fraterna plant produces small, black, flattened seeds that are around 2 mm in size. To propagate the plant through seeds, collect the mature seeds and allow them to dry for a few days. Once the seeds are dry, they can be sown directly onto aquatic soil in a container. The container should be filled with water, and the seeds should be placed on the surface of the soil. Keep the container in a warm, bright place, and ensure that the water level is maintained during the germination period.
Propagation by Division
Division is another common method of propagating Nymphaea fraterna. To propagate the plant through division, remove the plant from the water and cut the rhizome into sections containing at least one growing tip. Each section can then be planted in its own container filled with aquatic soil and placed in water. Ensure that each plant has enough space to grow, and that the water level is maintained.
Propagation by Cuttings
Propagation by cuttings is a popular method for propagating Nymphaea fraterna. To propagate the plant through cuttings, select healthy stems from the parent plant and cut them into sections around 15 cm in length. Remove the lower leaves from the cuttings, leaving only a few leaves at the top. The cuttings can be planted in a container filled with aquatic soil and placed in water. Keep the container in a warm, bright place and ensure that the water level is maintained during the rooting period.
Propagation of Nymphaea fraterna is relatively easy, and the plant is an excellent addition to any aquatic garden or pond.
