Q.Repotting Clematis
I’d like to know how and when I could transplant my clematis plants from container to bigger containers. Also, is it possible to combine 2 plants together in 1 bigger pot? Thank you.

If the plants need the same amount of water and sun, it is OK to plant them in the same container. You can transplant in fall, but the sooner the better. It takes them a long time to resettle their roots and typically don't like to be moved. Spring would be preferable for the move since you are in hardiness zone 5. Most clematis are hardy to zone 4, so your clematis would do better if it is moved into the garage for the winter and watered only about once a month. A container offers little protection from the elements.
