Isoetes storkii requires consistently moist to submerged conditions. Never allow the substrate to dry out. Submerge the plant in a shallow aquarium or pond environment, ensuring the roots are always covered by water.

Water changes should be infrequent, only to maintain water quality if needed.

Pruning is generally not required for Isoetes storkii. Remove any dead or decaying leaves by gently pulling them away from the base of the plant. This helps maintain plant health and prevent rot.

Avoid cutting healthy foliage unless absolutely necessary.

Isoetes storkii primarily propagates through the formation of new cormlets from the parent plant. These can be carefully separated when they reach a sufficient size and planted in suitable substrate.

Division of the main corm is also possible but less common.

Repotting is rarely necessary for Isoetes storkii. If the plant outgrows its container or the substrate degrades, repot into a slightly larger pot with fresh, nutrient-rich aquatic substrate.

Ensure the new substrate is thoroughly rinsed to avoid clouding the water.
