As an aquatic plant, Lemna minor requires a stable freshwater environment. It thrives in still or slow-moving water bodies like ponds, aquariums, or water gardens.

Ensure the water quality is maintained, avoiding extreme pH fluctuations or heavy pollution. Regular replenishment of evaporated water is necessary to keep the fronds submerged and healthy.

Pruning for duckweed mainly involves removal to control its rapid spread. If allowed to cover the entire water surface, it can block sunlight for other aquatic life and deplete oxygen.

Regularly skim off excess fronds with a net to maintain desired coverage and prevent it from becoming a nuisance in the aquatic environment.

Lemna minor propagates primarily through vegetative budding, where new fronds bud off from existing ones. It also produces turions for overwintering.

Propagation is extremely easy; simply introduce a few fronds to a suitable water body, and they will multiply rapidly under favorable conditions, quickly colonizing the surface.

Repotting is not applicable for this free-floating aquatic plant. It does not have roots that anchor it to a substrate or require a pot.

Its "repotting" equivalent is managing its population density within its aquatic habitat, which is done through removal of excess fronds rather than transplanting.
