Answer: The best time to dig and move bulbs is after the foliage has died down. You don't want to cut the foliage off until it has withered down because while green, it is busy sending energy from the sun down into the bulb to store for next year's growth spurt and flower. Once the foliage dies down you can move the bulbs.
I have found that clematis takes a couple of years to become established in the garden. Once the roots are happy, you'll see lots of top growth. Clematis likes full sun on the top of the plant but prefers to have the roots cool and shaded. If you can plant something in front of clematis to shade the roots, it will appreciate your kindness.
Best wishes with your garden!
