Planting & Care

Plant Jackmanii Clematis vines in well-drained soil in a location receiving full sun to partial shade. Dig a hole twice the width of the root ball and plant at the same depth as the container. Water regularly during the establishment period to keep soil evenly moist. Providing a trellis or support structure will help guide its climbing growth. Light pruning in late winter can remove tangled or overcrowded growth and encourage strong flowering the following season.
