Pruning Instructions: Clematis in group 3 consist of late-flowering species that bloom from mid-sumer into fall. This group flowers on the last 2 to 3 feet of the current season's growth (new wood). They are easy to prune because you do not need to maintain any old wood. In February or March, cut each stem to a height of 1 or 2 feet. Although you will be removing good stems and buds, this treatment keeps these vigorous growers in bounds. If not pruned, these vines will quickly become a mass of old diseased woody stems producing very few flowers. Always make sure to leave two good buds below where you make your cut. New growth will emerge from these buds to produce the current seasons vines and blooms.
