How to Grow Rock Cress Plants:

Growing Rock Cress plants is easy. Grow Rock Cress in full sun. Plants will tolerate a light or partial shade. They will do well in fair to poor soils, with a neutral to slightly alkaline pH. Sandy, loam, or clay soil is fine. It should be loose, well draining. Keep soil moist during germination.

Rock Cress likes slightly dry soil. Water only during the hottest, driest period of summer. Add a general purpose, high nitrogen fertilizer when first planting, to help them to get a good start. Add a high Phosphorous fertilizer just before blooming.

Rock Cress will bloom in the spring of the second year after planting, and every year afterward. (They are worth the wait!) Prune plant and remove dead flowers after blooms have died, to give the plant a clean, healthy look, and to promote new plant growth.

Rock Cress plants are hardy, and will survive light frosts before going dormant for the winter months.
