For the castela genus, a well-draining soil type is crucial to prevent root rot; however, it tolerates a wide range of soil conditions. These sun-loving plants require full to partial sunlight, and moderate watering needs, letting the soil dry out slightly between waterings. When planting, dig a hole twice the size of the root ball and place the plant in the centre. Backfill with soil, water thoroughly, and mulch to retain moisture. Specific care may vary among species. Observing plant growth pattern can provide useful insights.
