Bocking 14 Comfrey problems — and how to fix them
Bocking 14 Comfrey (Symphytum x uplandicum 'Bocking 14') 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.
Regrows from root pieces
Any taproot fragment left when digging will resprout, so place it where it can stay; this same trait makes it nearly impossible to weed out.
Comfrey rust
Orange fungal pustules can mar leaves in damp years; cut foliage to the ground and bin it to interrupt the disease cycle.
Slow first-year establishment
Root offsets can sulk and grow little in their first season before bulking up; be patient and keep them watered.
Leaf wilt in heat
Large leaves droop in hot, dry weather; deep watering or a post-drought cut prompts fresh, turgid regrowth.
