Water: Eared redstem flourishes in humid, wetland-like environments and requires consistent moisture. It prefers to be watered weekly and exhibits moderate drought tolerance. As an aquatic plant, it thrives outdoors where it can utilize seasonal rainfall for optimal growth.

Fertilize: Eared redstem requires balanced nutrition, particularly with a 10-10-10 NPK fertilizer during active growth. Transition to high nitrogen for leaf development, using half the rate for potted plants. Water before fertilizing to enhance nutrient absorption and observe for signs of nutrient imbalance.

Pruning: Eared redstem features vibrant red stems and small flowers. Prune in early to late spring by removing dead stems and thinning crowded areas for airflow. Use clean, sharp tools and prune above leaf nodes to promote healthy growth and flowering.

Propagation: Eared redstem thrives in semi-aquatic environments and can be propagated by careful seed sowing. Use a well-draining substrate, evenly distribute the seeds, and cover lightly. Maintain consistent moisture without waterlogging for successful germination, ensuring optimal conditions for growth.
