Blooming on new wood, 'Miss Molly®' should be trimmed in late winter or early spring. During the growing season, deadheading can keep this beauty looking tidy, but some gardeners do not bother to remove spent blooms from this cultivar. In many ways, it takes care of itself. Plant in well-draining soil, water well, and then allow the top layers of soil to dry out before watering again. Ensure that this pollinator-magnet gets full sun most of the day.
