The nerium genus typically prefers well-drained, fertile soils and a sunny location. Before planting, enrich the soil with compost and loosen it deeply to facilitate root development. Position the nerium plant in a hole twice as wide and deep as its root-ball, backfilling with soil. Water thoroughly after planting, and keep the soil slightly moist, not waterlogged. For best results, take note of the specific needs of each species within the nerium genus.
