Water: Rough jointfir is highly drought-tolerant and thrives in low-humidity environments with minimal moisture. Water sparingly, ideally every 2-3 weeks, to mimic its native dry habitat. Its water-storing capacity makes it suitable for xeriscaping and enduring prolonged dry periods.

Fertilize: For rough jointfir, use a balanced, slow-release fertilizer sparingly in spring and fall, applying no more than a teaspoon per plant to prevent root burn. Reduce feeding in winter and ensure thorough watering post-application. Overfertilizing can harm rough jointfir's natural hardiness.

Pruning: Pruning rough jointfir in early to late winter enhances shape and vigor by removing dead or weak branches. This practice improves air circulation and light penetration, promoting healthy growth and preventing diseases, thereby boosting rough jointfir's resilience and aesthetic appeal in gardens.

Propagation: Rough jointfir can be propagated via healthy, mature stem cuttings placed in a well-draining medium. Maintain consistent moisture and provide indirect sunlight for optimal rooting. Careful handling is essential to prevent damage to the fragile stems during propagation.
