water mimosa

Neptunia oleracea

Water Mimosa is a shrub-like annual plant that is native to tropical regions of South and Southeast Asia. Its round leaves are a vibrant green, and can reach up to 12 cm in width. It produces small yellow flowers which turn into compact pods after pollination. Its roots are well adapted to wet conditions, as water Mimosa is highly aquatic, and can be found growing in flooded areas. It is traditionally used in Ayurvedic medicine for treating joint pain, and as an anti-inflammatory. It is also used as a soil conditioner and for flood control.

watering

Water mimosa (Neptunia oleracea) is a tropical plant species that prefers to remain consistently moist. It should be watered thoroughly once a week, but may need more frequent watering in warm and dry conditions. Water mimosa should be watered from below, allowing the water to absorb through the drainage holes in the bottom of the pot. Avoid wetting the foliage to prevent fungal and bacterial diseases.

sunlight

Water mimosa, which is also known as Neptunia oleracea, needs various levels of sunlight to stay healthy. It grows best when it gets between 6 to 8 hours of direct sunlight every day, with a break during the hottest part of the day. Full sunlight will also help strengthen the colouring of the leaves. In areas where the climate is too cold for the plant to survive outside, it can be grown indoors near a south or west-facing window. If grown indoors, you should provide artificial light for 14+ hours per day for best results.

pruning

Water mimosa should be pruned regularly and lightly. Pruning is best done when the plant is actively growing in spring and early summer. Pruning should organically maintain the desired shape and size, but should not be done too harshly as it can cause damage to the plant. Generally, it is best to selectively remove individual branches that have become spindly or leave gaps in the foliage. It is important to use sterilized tools when pruning.
