Planting and maintenance
How to plant and maintain the Horsetail?
It is planted near the pond, in a constantly wet soil, or directly in the pond, immersed at 5 cm or 2 inches (immersion tolerance ranging from 0 to 10 cm or 0 to 4 inches). The soil should be moderately rich and if possible with an acid tendency (potting soil for aquatic plants). The presence of cilice (clay) is also recommended.
Plant it in a well-defined area so that it does not over-invade your pond (use a tray, pot, root barrier…). In addition, it multiplies the stems in the same place which will be prettier. Allow 3 to 5 feet per m2 for a good base.
It will enjoy a sunny exposure to partial shade.
It resists cold and does not fear freezing. It should only be protected in case of temperature below -10°C or 14°F.
Finally, it does not require any size. However, remove the dry stems regularly.
