Comfrey is not a very common plant but there are some of us that do grow and use it. Rest assured that you are not alone.

I have some too, but I mostly have it for the bees, which adore it. I used to have stinging nettle, which I used for fertilizer and in the compost, but it became too much of a pain to keep under control.

It's one of the "old-fashioned" plants which were previously very common.

It draws up loads of macro and micro nutrients from deep in the ground. I've read that its root system can easily be 6ft deep or more! I don't understand why it's not so popular any more. Why it even looks good with its big green leaves and purple flowers which the bees love. No work to take care for - the only problem I've ever seen is it being chewed on by slugs when it's first emerging in the spring. Well worth reading about its medicinal uses also.

Comfrey has what many term the appearance of an unwanted plant, a "weed" and that is why many do not grow it today. Its growth can be aggressive.

Comfrey is native here but also very widely grown by gardeners. There is a specific strain, Bocking 14, developed by the Henry Doubleday Research Association, for organic gardeners' use.

I have a patch which I just add to the compost heap. It can be cut several times a year. I've never bothered to make liquid fertiliser out of it. When I have spread it around plants I've not observed any difference but I was not doing it at all scientifically.

I must have the Bocking14 variety because I've never had a problem with it spreading. In my mind it's not just a very useful plant but a rather nice looking one also - huge dark green leaves tipped by clusters of purple flowers.

Re it being a weed....dandylion, plantain and stinging nettle are all considered weeds but they too are great at "mining" elements from the soil. Give your worm bin and/or compost a nutrient boost, just toss in the leaves and let nature do the rest.
