Plants from the halocnemum genus thrive in salty, well-draining soils and require full sunlight, reflecting their natural coastal and desert habitats. When planting halocnemum, select a site with light, sandy soil, or amend your soil to improve drainage. Space the plants to allow for spreading growth. Water moderately until established, then reduce frequency, as halocnemum is drought-tolerant. Avoid overwatering to mimic their native arid conditions. While most halocnemum species share these requirements, always confirm specifics for the chosen species.
