Wolffia brasiliensis requires a constant supply of clean, still, freshwater. Avoid tap water with high chlorine or heavy metals. Maintain a stable water level to prevent the plants from drying out.

Over time, water may need to be topped up to compensate for evaporation, ensuring the plants remain fully submerged.

Pruning is not applicable to Wolffia brasiliensis as it does not possess true stems or leaves that require cutting. Its growth is by budding.

Simply remove any decaying or unwanted plant matter to maintain water quality and aesthetics. This ensures the health of the remaining population.

Propagation of Wolffia brasiliensis is exceptionally rapid and occurs naturally through budding. New plantlets develop directly from the parent plant. Simply allow the population to grow.

When the density becomes too high, excess plants can be gently scooped out and used to start new colonies.

Repotting is not a standard practice for Wolffia brasiliensis. As it is a free-floating aquatic plant, it does not have roots that anchor it to a pot.

To 'repot', simply transfer a portion of the existing colony to a new, clean aquatic environment or container with suitable water conditions.
