barberry shrub rejuvenation

I'm trying to save 3 barberry shrubs that are dying out and wondered if there is a way I can save them. Can I cut them down at base and will they sprout new growth? I trimmed all of them back this spring, but one did not sprout any new growth. Would like to save them if possible. Any advice would be appreciated. thanks.

sawfly worm?

I've noticed past month my groundcover getting ravaged & just today noticed what I think are sawfly worms..hundreds of them: pale green, thin, approx. 1" long with black eyes. When touched they curl up. Never heard of or saw this before. I live in Clinton, Iowa. How do I get rid of them? Can I spray now to kill the active ones so their larvae can't winter over, and then spray again in spring to kill the larvae? My beautiful groundcover ruined at this point.
