Troubleshooting
Russian Comfrey problems — and how to fix them
Russian Comfrey (Symphytum x uplandicum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Hard to remove once planted
Regrows from any root fragment left in the soil, so siting it permanently is the safest approach; container-grow if you may want to move it.
Comfrey rust
Orange rust pustules can appear on foliage in wet seasons; cut all leaves to the base and dispose of them to limit spread.
Leaf scorch in drought
Big leaves wilt and brown at the margins in hot, dry spells; water deeply or accept a flush of fresh regrowth after rain.
Slug grazing on regrowth
Soft new leaves after cutting are attractive to slugs; vigorous plants typically recover without intervention.
