C. ‘Elsa Spath’ , can also be pruned in a similar fashion but this is not as essential.
Pruning has two main functions. It increases general vigour and helps to ensure a good flowering season. Like many other garden plants, Clematis appreciate an annual structural overhaul. Not only does this allow us to keep unruly plants in check and remove dead or diseased plant material, but it also reduces the opportunity for stems to overlap, form open wounds and become infected. By pruning the plant back to two strong buds on each stem, around 8-10” from the ground, we can encourage plants to flower profusely. Group three plants flower on current years growth and by pruning in this way we improve the plants overall health and help it to put its energy in to creating new healthy shoots and blooms.
