Liquid fertiliser from comfrey

Back in the middle of May I took the first cut of comfrey and piled it up to let it wilt:

A couple of weeks later it was looking like this:

I chopped it up a bit and stuffed it into an old water container...

...with a bit of wood and a brick over it to squash it down...

...covered it up and stuck it behind the cabin:

 Now if we take a look inside it's turning to liquid...

...I'll dilute this as needed to use as a feed on my tomatoes. You can of course just chuck your comfrey leaves into a water butt and make your feed that way but if you do it'll smell like a rotting corpe. By making a concentrate then diluting it the smell isn't nearly so bad.
