Q.Can I replant this fall and move back to original place in spring
I want to dig up my plant and reset in another bed until spring. The original bed is in terrible condition and I want to tear it out and redo it in the fall. I do not want to lose my Coreopsis, as I love its yellow flowers.

Coreopsis should do well being moved this fall. Prepare the temporary bed and move the plants. Water the plants well for the first 2 weeks, then you can cut back. Mulch around the plants for moisture retention and winter protection.
