DETAILS

Care Instructions
Giant Horsetail prefers bright, indirect light and thrives in consistently moist conditions. It does well in moderate temperatures and high humidity. Ensure the plant is kept in a location where it can receive ample light without being exposed to direct sunlight for extended periods.
Soil
This plant prefers loamy soil that retains moisture well. It is important to keep the soil consistently wet or even waterlogged, as Equisetum giganteum naturally grows in marshy environments. Good drainage is essential to prevent root rot.
Fertilizer
Equisetum giganteum does not have high fertilizer requirements. If desired, a balanced, water-soluble fertilizer can be applied sparingly during the growing season to support healthy growth.
Repotting
Repotting is generally not necessary for this plant unless it outgrows its container. If repotting is needed, do so in the spring. Carefully transfer the plant to a larger container with fresh, loamy soil, ensuring the roots are not damaged.
Propagation
Propagation of Giant Horsetail is typically done through division of the rhizomes. This can be done in the spring or early summer. Carefully separate the rhizomes and plant them in moist, loamy soil, ensuring they are kept consistently wet.
Pruning
Pruning is not typically required for Equisetum giganteum. However, if the plant becomes too tall or unruly, you can trim back the stems to maintain a desired height and shape.
Toxicity
Equisetum giganteum is not known to be toxic to pets or humans. However, it is always advisable to keep plants out of reach of pets and children to prevent any accidental ingestion.
Additional
Giant Horsetail is a fascinating plant with a prehistoric lineage, often considered a living fossil. It can be an interesting addition to water gardens or naturalized areas where its unique appearance and growth habit can be appreciated.
