Before buying more heuchera need to know what to do with woody root spurs I’ve only just noticed, and wiry root system at end – dangling and looking parched, if not dead. Any simple advice please.
Heucheras can go woody (which is what you have described)
Easy to sort out …
Just plant deeper ..don’t bury the crown, only the woody stem.
Give it a feed this stimulates new growth
Hope this helps
