Water: Annual rockcress originates from rocky terrains and efficiently retains moisture, demonstrating excellent drought tolerance. It requires moderate watering twice a week during growth. Preferring outdoor cultivation, annual rockcress thrives in well-draining soil, especially when establishing its root system.

Fertilize: Annual rockcress thrives with balanced fertilizers during the growing season and high nitrogen after flowering. Monthly half-strength applications enhance vigor and blooms, with reduced frequency in dormancy. Monitor annual rockcress's response to adjust care and avoid root burn for optimal growth.

Pruning: Annual rockcress features delicate white flowers on slender stems and requires minimal pruning. Early to late spring is ideal for trimming spent blooms and removing damaged stems to enhance airflow and health, while post-flowering pruning improves aesthetics and vigor, promoting longer blooms and reducing disease risk.

Propagation: Annual rockcress is propagated by sowing in a well-draining soil medium that supports germination. Consistent moisture levels are essential without soil saturation. A light cover of soil or vermiculite aids seed-to-soil contact, while gentle care during seedling growth fosters healthier plants.
