Marsilea aegyptiaca thrives in consistently moist to submerged conditions. Maintain water levels in its container, ensuring the substrate remains saturated. Avoid letting it dry out, especially during active growth.

In natural settings, it grows in shallow water bodies or waterlogged soil.

Pruning is generally not required for Marsilea aegyptiaca unless it becomes overgrown or to remove dead or damaged fronds. Trim back leggy growth to encourage a more compact form.

Use clean scissors or a knife to make precise cuts at the base of the frond.

Marsilea aegyptiaca can be propagated through division of rhizomes or by collecting spores. Separate healthy rhizome sections, ensuring each piece has at least one growth point, and replant in suitable substrate.

Spores can be collected from mature fronds and sown in moist conditions.

Repotting is usually only necessary when the plant outgrows its container or the substrate becomes depleted. This is best done in spring.

Gently remove the plant, divide if desired, and replant in fresh, nutrient-rich aquatic substrate in a larger pot or pond section.
