Some varieties of clematis have a tendency to fewer stems than others, but in many cases this is created by our pruning habits. Every type 1 and 2 clematis benefits from being pruned hard at least 1, or even 2 times in the first year in your garden, semi permanent or permanent container. The time to do this is when growth seems to be stalled, or immediately after those long awaited first blooms. It is better to do this in the spring and early to mid summer. In the fall it is better to let the plant go into dormancy with the stem(s) left unpruned.
For clematis that continue to have one stem, even if they have been pruned as directed, it is important that as the first flush of blooms wane in the first few seasons to continue to re prune the plant. Remember to fertilize the plant after you prune.
For clematis that do not respond to your efforts, we suggest landscaping around the plant’s tendency.
