Looking to plant a Clematis and help my existing one
I currently have a Jackmanii and it doesnt do very well I have tried cutting it back in the fall and also letting it be for the winter either way I only get new growth from the ground and very few flowers. I am looking to plant a new Clematis I would like to find one that possibly blooms all summer in zone 5 and I prefer the larger flowers compared to the smaller ones. Any suggestions for what I might purchase or how to bring my Jackmanii back to life.
Thanks in advance
