Pilularia americana thrives in consistently wet or submerged conditions. Maintain a waterlogged substrate or keep the plant fully submerged in still or slow-moving water.

Avoid letting the soil dry out at all times, as this aquatic fern requires high moisture levels to survive and flourish.

Pruning is rarely necessary for Pilularia americana. If the plant becomes overly dense or if any parts appear yellow or unhealthy, you can carefully trim away the affected sections.

Use sterile scissors to prevent the spread of any potential diseases. Focus on maintaining a tidy appearance.

Propagation of Pilularia americana is typically done by division. Mature plants can be gently separated into smaller clumps, ensuring each division has healthy rhizomes and roots.

These divisions can then be replanted in suitable wet or submerged locations to establish new plants.

Repotting is usually only necessary if Pilularia americana outgrows its container or if the substrate needs refreshing. This is best done during the spring growing season.

Carefully transfer the plant to a larger pot with fresh, waterlogged aquatic soil, ensuring the rhizomes are well-covered.
