Light Requirements
Castalia mystica Salisb. prefers to grow in full sunlight to partial shade. In areas with intense sunlight, partial shade may be necessary to prevent damage to the plant.
Temperature Conditions
The plant is typically found in freshwater wetlands, lakes, and ponds and is tolerant of a wide range of temperatures. However, it grows best in a temperature range of 15-25°C (59-77°F).
Soil Requirements
The plant prefers to grow in nutrient-rich soils with a neutral pH range between 6.5 and 7.5. It prefers a soil that is heavy in organic matter, such as sandy loam. The water level should also be kept consistent, as the roots of this plant grow best when submerged in water.
Cultivation methods
Castalia mystica Salisb., commonly known as mystic water lily, is a beautiful aquatic plant that requires specific cultivation methods to thrive well. The plant can be grown in pools, ponds, and aquariums, but it prefers still or slow-moving water. Choose a site that receives at least 5 hours of direct sunlight a day and has a temperature range of 20 to 30 °C.
To cultivate the plant, prepare the planting area by removing any debris or floating plants. Plant the lily in a container filled with loam or humus. Cover the roots with a layer of small stones to ensure they remain in place. Once planted, place the container in the water and gently submerge it, so the leaves float on the water's surface.
Watering needs
Castalia mystica Salisb. thrives on constant access to clean water. The plant needs water that is rich in nutrients and free of toxins, pollution, or algae. The water temperature should not be too hot or too cold, as it may affect the plant's growth. Water the plant daily to ensure it receives adequate moisture throughout the growing season. If the plant is growing in a pool or pond, check to ensure the water level is stable to avoid exposing the roots to air and drying out.
Fertilization
Castalia mystica Salisb. requires adequate fertilization to flower and produce healthy leaves. The plant can be fertilized with pond tabs or aquatic fertilizer. The fertilizer should be applied monthly during the growing season. Ensure the fertilizer is scattered evenly over the water surface to reach all parts of the plant. Over-fertilization can lead to the plants overgrowth, which may affect its overall health and attractiveness.
Pruning
Pruning is an essential aspect of Castalia mystica Salisb. cultivation. The plant should be pruned to maintain its shape and size. Remove any yellow or dead leaves, flowers, or debris from the plant, as they may harbor pests or diseases that could affect the plant's health. If the plant becomes too large, divide it into smaller segments and repot it in separate containers. Pruning should be done at the start of the growing season to encourage new growth and improve the plant's overall health.
Propagation of Castalia Mystica Salisb.
Castalia mystica Salisb., commonly known as the water fringe or neer-vallies in Afrikaans, is a perennial aquatic plant that belongs to the family Nymphaeaceae. It is native to Southern Africa and is widely cultivated in water gardens and ponds for its attractive flowers and floating leaves. Propagation of this plant is primarily done by seed and division.

Discard any old or dead rhizomes and cut the remaining ones into small sections with at least one bud or sprout on each section. Plant the sections in a pre-soaked potting mix in containers that are at least 8 inches deep. Place the containers in a pond or aquarium that receives plenty of sunlight and has a water temperature of around 70°F. Keep the containers moist, and within a few weeks, new growth will appear.
