Maintain consistently moist soil or submerged conditions. For aquarium plants, ensure the water level remains stable and the substrate is saturated.

Avoid letting the plant dry out completely, as this can lead to rapid decline and death. Regular top-offs or water changes are essential for optimal health.

Pruning is primarily for managing growth and propagation. Simply trim stems to the desired length using clean scissors or a knife. Remove any yellowing or decaying leaves to maintain plant health and aesthetics.

The pruned stems can be directly used for propagation.

Canadian Waterweed propagates very easily through stem cuttings. Simply take a healthy stem cutting, at least 10-15 cm long, and plant it in the substrate or let it float in the water.

New roots and shoots will develop quickly from the nodes along the stem.

As an aquatic plant, Elodea canadensis does not require traditional repotting into larger containers. If grown in a pot, ensure it is a suitable aquatic planter.

If it outgrows its space, it can be thinned out, or excess growth can be removed or used for propagation elsewhere.
