Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.
How Far Apart Should You Plant a Franciscan nailwort?
Franciscan nailwort can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Franciscan nailwort?
Prune Franciscan nailwort while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
