When large enough to handle, transplant seedlings into 3 in. pots. Once rooted, place into the garden 12 in. apart.

Grow Rock Cress: Prefers part shade in hot climates, full sun where summers are relatively cool. Plants prefer lean soil, need well-drained soil. Cut back halfway after bloom. Flowers attract bees.
