Established Clematis vines can be trained on a trellis or trained against a structure, or sometimes used as a very unique ground cover.  Another interesting way to use a Clematis is to allow it to grow with another plant like a climbing rose or sprawling over a spreading Juniper.  Beautiful.  However you are growing your Clematis, now is the time to prune them before they start to grow.  Typically it is a good idea to cut the tops down to about 12-18”, rake out the leaves and apply 2-3” of shredded mulch around the roots.  Clematis like to have cool soil.  So easy to grow, so beautiful, and so very useful in the landscape.  An early spring haircut will help your plant produce healthy new growth and lots of flowers. Enjoy!
