Water: Rock tobacco thrives in humid, moist environments, needing weekly watering to mimic its rainforest origins. To ensure robust health, gardeners should provide adequate humidity and maintain consistent moisture during the growing season, especially as rock tobacco is often grown indoors.

Fertilize: For rock tobacco, balanced fertilization enhances growth, using high phosphorus fertilizers every four weeks during active growth. Reduce frequency in the dormant season, using quarter-strength doses to avoid nutrient overload. Always water rock tobacco before fertilizing and adjust based on plant response and environmental conditions.

Pruning: Rock tobacco benefits from strategic pruning during late winter to early spring while dormant. Key techniques involve removing dead leaves, shaping, and light thinning to enhance air circulation and promote growth. Caution is required to avoid over-pruning, which can stress the plant.

Propagation: Rock tobacco is propagated through leaf cuttings by placing a healthy leaf on well-draining soil with the cut end in contact. Maintain humidity and stable temperatures to encourage rooting. Use a sterile cutting tool for healthy growth, with new shoots indicating successful propagation.

Repotting: Repot rock tobacco every 2-3 years in spring, using a small to medium-sized pot that supports its bushy growth. Water consistently and provide bright, indirect light after repotting to ensure healthy, vibrant foliage.
