Water: Originating from moist environments, blackstonia prefers consistent moisture, thriving with weekly watering to sustain growth. It efficiently retains water while balancing drainage, and is typically cultivated outdoors, adapting to seasonal rainfall patterns that influence its growth cycles.

Propagation: Propagation of blackstonia occurs through seed sowing and division. Growth requires sunlight, temperate conditions, and well-draining soil. Stratification may be needed for seeds. For seeds, stratify, use a seed mix, maintain moisture, and transplant seedlings. For division, separate and replant clumps in spring or autumn.
