Calamus species thrive best in well-drained soil with full to partial sun exposure. They're also tolerant of wet conditions and can be grown near water bodies. To plant calamus, start by preparing a hole twice as wide as the root ball. Position the plant such that the top of the root ball is level with the soil surface. Backfill, firm the soil, then water thoroughly. For best results, maintain consistent moisture levels. Though similar, different calamus species may have unique needs, so research your species beforehand.
