How to Propagate Sweet Autumn Clematis?
Propagating Sweet Autumn Clematis is relatively easy. You can propagate it through seeds, cuttings, or by layering. The most common method is by taking softwood cuttings in the spring or early summer. Cut a healthy stem about 4-6 inches long, remove the lower leaves, and dip the cut end into rooting hormone.

When to Prune Sweet Autumn Clematis?
Pruning Sweet Autumn Clematis is essential for maintaining its shape and encouraging more blooms. The ideal time to prune is in late winter or early spring before new growth begins.

Can Sweet Autumn Clematis Grow in a Pot?
