For the genus scaphium, well-draining, fertile soil with a neutral to slightly acidic pH is ideal. These plants typically prefer a sunny to partly shaded location with consistent moisture, but they can tolerate some dry periods once established. To plant scaphium, begin by loosening the soil and incorporating organic matter. Plant at the same depth as the container they came in, spacing individuals according to their expected size at maturity. Water thoroughly after planting and maintain soil moisture while the plants establish. Avoid overwatering to prevent root rot. It's essential to research the precise needs of different scaphium species, as there may be variations in their cultural requirements.
