Comfrey Advice

Mines between  a Silver birch tree and the blackberries I've never let it go to seeds in-case it spreads.

I got stung off a bee a couple of years ago whilst cutting it down while it was flowering.

Serves me right!

Since then I always take two to three cuts BEFORE flowering and possibly leave the last cut of the season until AFTER flowering.

I doubt mines Blocking 14 the plant came from a friend of a friends  allotment,  so don't want to risk it self seeding.
