I planted a Jackmanii clematis this year and have thoroughly enjoyed it. I've read I should cut it back to 1' or so in late February or early March, but I have a question. When I bought the plant it was wrapped all around this little wire trellis that was stuck in the pot. I carefully removed the plant (trellis and all) and planted it and it's done very well this year, but when I cut it back how do I handle that little trellis? Do I just leave it and cut the vine above it? The vine is wrapped quite a lot around it.
