Propagation of Nymphaea Nelsonii Burtt Davy
Nymphaea nelsonii Burtt Davy, also known as the Cape blue water lily, is a stunning aquatic plant that is native to South Africa. The plant is known for its beautiful blue blooms and is a popular choice among water gardeners. Propagating Nymphaea nelsonii Burtt Davy can be done using various techniques, as outlined below:
Propagation by Seed
Propagation of Nymphaea nelsonii Burtt Davy by seed is possible, although it requires patience and attention to detail. Collect the seeds from the plant as soon as the flower fades and ripens. Sow the seeds in pots or trays filled with a well-draining aquatic soil mix, and cover them lightly with soil. Keep the soil moist and warm (around 25°C) by covering pots with cling wrap or propagating domes. Seedlings should start to emerge in 2-3 weeks, and after 6-8 weeks they can be transplanted into a pond or larger containers.
Propagation by Division
Dividing the plant is a quick and easy way of propagating Nymphaea nelsonii Burtt Davy. To do this, carefully remove the plant from the pond or container and gently separate the rhizomes (roots) by pulling them apart. Each division should have several healthy shoots and roots. Plant the divisions in individual pots or directly into the pond, making sure that the crown of the plant is not buried too deeply (just below the soil surface). Water thoroughly and keep the soil moist until new growth is established.
Propagation by Cuttings
Propagation of Nymphaea nelsonii Burtt Davy by stem cuttings is not always successful, but it can be attempted in early spring or early summer. Take 10-15 cm long cuttings from the plant's healthy stems and remove the bottom leaves. Plant the cuttings in small containers filled with an equal mix of aquatic soil and sand, ensuring that at least one node is under the soil. Cover the container with clear wrap and place it in a sunny location. Keep the soil moist. Rooting should occur in 3-4 weeks, and after the roots are established, the cuttings can be transplanted into the pond or larger containers.

Diseases
One of the most common diseases that can affect Nymphaea nelsonii Burtt Davy is fungal leaf spot. This disease is characterized by small, circular or angular spots that appear on the leaves, which can expand and merge to form larger irregularly shaped lesions. To manage fungal leaf spot, it is important to remove any infected leaves and dispose of them properly. Avoid overhead watering, which can promote the growth and spread of the fungus. Fungicides can also be used but must be applied according to instructions.
Another disease that can affect Nymphaea nelsonii Burtt Davy is crown rot, which is caused by fungi that thrive in wet and muddy conditions. The symptoms of crown rot include wilting, yellowing, and softening of the crown. To manage crown rot, it is important to plant the waterlily in well-draining soil and avoid overwatering. Remove any infected parts and treat the plant with fungicides.

One of the most common pests that can affect Nymphaea nelsonii Burtt Davy is the aquatic snail. These snails feed on the leaves, stems, and flowers of the waterlily, which can cause significant damage. To manage aquatic snails, physical removal can be done using a net or trap. Chemical control can also be done using snail baits that are safe for aquatic plants and animals.
Another pest that can affect Nymphaea nelsonii Burtt Davy is the waterlily beetle. These beetles feed on both the leaves and flowers of the plant, which can cause significant damage and reduce its aesthetic value. To manage waterlily beetles, physical removal can be done using a net or by handpicking the beetles.
