Hi, I recently read an article on the internet about propogating clematis. Below is an excerpt:

The viticellas are easy to propagate. If you are skilled in taking cuttings then you will find these much easier than the Large Flowered clematis in taking. But the simplest way of increasing the size of your plant is to bring a long stem down and slip it into the ground alongside your plant. You can do this on both sides. Soon you will have three plants instead of one. You can also layer the stems very easily. In less than a year you will have one or more extra plants.

Could someone tell me how to do this (the long stem down and when should I do it). This is something I would love to do with my Polish Spirit.

Thanks for your help.
