Soil Requirements
The plant thrives in soil that is rich in nutrients and organic matter. The soil should be well-draining and slightly acidic with a pH between 6.0 to 7.5. A good water retention capacity is necessary to keep the soil moist.
Cultivation Methods
Nymphaea nouchali Burm.f., commonly known as blue water lily or star lotus, is a perennial plant that can be grown in ponds or water gardens. It prefers a warm climate, and it can be grown in full sun to partial shade. To cultivate the plant, start by preparing a shallow planting container with a layer of soil at the bottom. Place the tuber into the soil and cover it with a thin layer of gravel. The plant will begin to sprout after a few weeks.
Watering Needs
The blue water lily requires consistent watering to thrive. It is an aquatic plant, therefore it requires water to grow and develop. Keep the water in the container consistently moist, but be careful not to oversaturate it. Overwatering can lead to root rot, which can harm or even kill the plant. Additionally, be sure to change the water in the container frequently. This helps maintain the quality of the water and prevents harmful algae growth.

Use a balanced aquatic plant fertilizer and follow the manufacturer's instructions regarding the dosage and frequency of application. Apply the fertilizer during the growing season, which typically occurs from late spring to early fall. Be sure to disperse the fertilizer evenly to avoid over-concentration in one area of the container.
Pruning
Regular pruning is essential for maintaining the health and aesthetic appeal of the blue water lily. Trim back any yellow, dead, or decaying leaves and stems to maintain good plant health. Additionally, cut off any flowers once they fade or die, as this encourages the development of new flowers. Lastly, if the plant becomes too large for the container, it may be necessary to divide it and replant it into a larger container or a pond.

Diseases
1. Leaf Spot - Leaf spot is a common fungal disease that affects the leaves of the water lily. It appears as small, dark spots on the leaves, which later turn yellow and fall off. To manage this disease, remove the infected leaves and destroy them. Also, avoid overhead watering as it promotes the growth of fungi. Fungicides may also be used to prevent the spread of the disease.
2. Rust - Rust is another fungal disease that affects the leaves of Nymphaea nouchali Burm.f. It appears as small, orange-brown spots on the leaves, which later turn reddish-brown. To manage this disease, remove the infected leaves and destroy them. Also, avoid overhead watering and keep the area clean to prevent the spread of the disease.
Pests
1. Aphids - Aphids are small, soft-bodied insects that suck the sap from the leaves and stems of the water lily. They can stunt the plant's growth and cause the leaves to curl and distort. To manage aphids, spray the plant with a strong jet of water to dislodge them. Predatory insects like ladybugs and lacewings can also be introduced to eat the aphids. In severe infestations, insecticidal soap or neem oil can be used.
2. Snails and slugs - Snails and slugs are common pests that feed on the leaves and stems of water lilies. They leave large holes in the leaves and can cause extensive damage to the plant. To manage these pests, remove any debris or decaying matter around the plant, as they provide a conducive environment for snails and slugs. Place copper barriers around the pond to prevent their entry, and use bait traps or handpicking to control their population.
By following these disease and pest management practices, you can keep your Nymphaea nouchali Burm.f. healthy and thriving.
