Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Maintain water levels to keep roots submerged or soil consistently waterlogged. Water evaporates quickly in warm weather, so check frequently.
Prune regularly to control spread and remove dead or yellowing foliage. Trim stems to maintain desired height and prevent overcrowding in ponds.
Easily propagated by stem cuttings or division. Simply place healthy stem sections in water or moist substrate; they will root readily.
Repotting is generally not necessary for pond-grown plants. Container-grown plants may need repotting every 1-2 years if they become root-bound.
