Heuchera Coral Bells - Root Rot or Crown Rot
I have two coral bell plants, each in the same rectangular flower bed, but at opposite ends. They receive partial sun, but mainly shade. They've been planted since late April, and up until now, thriving. One is still thriving, but the other is wilting and shriveling up (not drying up). It isn't for a lack of moisture due to weeks of regular watering, and now, many recent thundershowers. From what I've researched, it could very well be crown rot or root rot. I've also read that a fungicide might fix the problem, but I'm not sure where to start. Has anyone experienced this, and if so, did you use a specific fungicide for treatment? Is there an organic fungicide that will treat root rot or crown rot? Do you think the plant will still live? Any input or advice will be greatly appreciated.
