Clematis stopped growing
I have 2 clematis plants in a window box planter that I want to grow up a wrought iron fence. I started the plants in small pots & once they grew big enough to reach the fence I transplanted them into the window box planter. They both continued to grow for a while, then they just stopped growing. I have watered when needed and fed them. They aren't dying, they just aren't growing. They've been in this "dormant" state for about 5 weeks with no change. How I can get them to start growing again?

Do you know what variety of clematis these are? Some types are dwarfs, reaching only several feet tall. Is it possible that these are one of the newer dwarf clematis? Another thought: clematis grow best when their roots are kept cool. By planting them in an above-ground window box, the root systems will be warmer than those grown in the ground. That may be enough stress on the plants to check their growth.
