Where do you recommend K buy comfrey from, to plant in the allotment?
Do I just need root cuttings, or should I buy actual plants.
Is all comfrey the same or is there a certain variety that is best, for turning into a liquid feed.
I live near the coast so you could easily collect seaweed, but I think comfrey is a better fertilizer.
Thank you

You want Bocking 14 which will not throw seeds.  I got mine from Ebay but you could ask other allotment holders if you could have a piece of root it they have them.
