Here's a tip...
Sometimes I have heuchera that are only 1-2 years old (so not ready to divide yet) that aren't filling out properly. They seem skinny and small, and the leaves are coming off one central area that is elongated, like a neck.
I was watching a video by Dan Heims (Terra Nova) and he mentioned this. His suggestion was to dig up the plant and re-plant it; burying the neck about 1 inch deeper than it was previously planted. He said this would cause the plant to send up new leaves and start to fill out within 3-4 weeks.
Well, I tried it and it works! Some of my uglier plants are now round and bushy. Just thought I'd mention it in case any of you out there are having this issue.
