Salvinia cucullata thrives in consistently moist to submerged conditions. It's an aquatic plant, so maintain a stable water level in its container or pond.

Avoid letting the water level drop significantly, as this can stress the plant and lead to wilting or desiccation of the floating leaves.

Pruning is generally not required for Salvinia cucullata. Its growth is naturally controlled by available space and light.

If the plant becomes excessively dense and starts to shade out other aquatic life, you can manually thin it out by removing excess mats of foliage. Dispose of removed material properly.

Propagation of Salvinia cucullata is very easy and occurs primarily through vegetative means. The plant readily produces new buds and branches along its rhizomes.

Simply allow the plant to grow; new plants will naturally form and detach, or can be gently separated and floated in suitable water.

Salvinia cucullata does not require traditional repotting as it is an aquatic plant that floats freely. If grown in a container, it will simply expand to fill the available space.

Removal of excess growth is the primary management technique, rather than repotting into a larger container.
