Water: Originating from rocky alpine regions, rockcress prefers well-drained soil and is drought-tolerant. Watering twice a week is recommended. Indoors, rockcress thrives in consistent light and controlled watering to prevent root rot, favoring cooler temperatures and moisture availability during spring.

Fertilize: Rockcress thrives with balanced fertilization to enhance growth and blooming. Apply high nitrogen fertilizers quarterly from spring to fall, avoiding over-fertilization. Adjust frequency based on seasonal and maturity needs, and water soil before fertilizing to prevent root burn, ensuring nutrient absorption for optimal health.

Pruning: Rockcress is a hardy perennial celebrated for vibrant blooms and ground cover. Prune post-flowering in late spring to promote bushy growth, removing spent flowers and leggy stems. Avoid cutting old wood. Regular pruning improves air circulation, reducing disease risk and fostering vigorous growth.

Propagation: Rockcress is a hardy perennial that thrives in rocky soils. Use a well-draining medium and pre-sow stratification for better germination. Lightly cover seeds and maintain consistent moisture during germination, while a temperate environment supports growth for future transplantation.
