Clematis not flowering. How do I identify and winterize?
I very new to perennials so I haven't overwintered anything yet. I have 2 Clematis, the Empress & one from Home Depot that's labeled "tall height" Clematis nothing else identifying about it. It has a typical size and shape lighter blue/purple color bloom.
They both seem to be doing well on the front porch of our house but since we brought the unidentified Clematis home it bloomed then grew like crazy. I cut it back some but since that initial bloom it's not done anything else?
The Empress Clematis had many blooms when we bought it and it has grown some but not as much as the other. I switched their spots since it didn't get as much sun and it does seem to have grown some but not quite as much as the other. It also hasn't bloomed since we potted it?
I read that some Clematis can be cut back to a few inches during the dormant seasons and other like the taller variety you just leave alone. How do I identify which ones I can cut back and which I don't
Also, how high should I actually cut it back and when?
Thanks in advance to anyone who can help! Rachel
I can post a picture in a few days if that would help?
