Wolffiella welwitschii thrives in consistently moist to flooded conditions. The substrate should be saturated, and for floating specimens, the water level should be maintained without allowing it to dry out.

Overwatering is not a concern; instead, prevent the roots from ever drying.

Pruning is generally not necessary for Wolffiella welwitschii as it grows and reproduces rapidly, naturally thinning itself out. If the mat becomes excessively dense or starts to outcompete other aquatic plants, simply remove excess growth by hand or with a fine mesh net.

Propagation of Wolffiella welwitschii is exceptionally easy and occurs through budding. New plantlets develop from the parent plant and detach when mature.

Simply ensure adequate space and nutrients, and the population will expand rapidly on its own.

Repotting is not applicable in the traditional sense for Wolffiella welwitschii. As a free-floating aquatic plant, it does not have roots that anchor it to a pot.

It can be transferred to new aquariums or water bodies by scooping portions of the mat.
