Water: Smooth rockcress is well-suited for rocky terrains, preferring moderate moisture yet thriving in drier conditions. It requires weekly watering due to its drought tolerance, making it ideal for outdoor gardens in areas with variable rainfall.

Fertilize: For healthy growth, smooth rockcress requires balanced fertilizers during the growing season, shifting to high nitrogen types for leafy development. Fertilize quarterly, adjusting for size, and reduce in winter. Avoid over-fertilization to prevent root burn; novice gardeners should use half-strength solutions.

Pruning: Smooth rockcress features delicate white flowers and glossy leaves. Prune in early to late spring by removing damaged stems to promote growth and improve air circulation. Post-flowering pruning enhances next season's blooms. Use clean, sharp tools for effective maintenance and aesthetic appeal.

Propagation: Smooth rockcress thrives in rocky habitats and is best propagated by sowing scarified seeds in well-draining soil. Maintain consistent moisture without waterlogging. Young plants prefer partial shade but can acclimate to full sunlight as they mature.
