Is this suppose to be a compost tea? What is the purpose of preparing it like this rather than just adding it to the compost bin or as a cover crop? Is this a foliar spray?

I think you can still use it Hank though it may not smell of roses! Why not try some on one plant and see what happens? We only find things out by trial and error if nobody comes up with an answer. Put a clothes peg on your nose first...

Thanks S, I spread it round the bottoms of my tomato plants this morning - couldn't smell anything much. Then son came into the front door, a long way from where I'd been watering and immediately said " phooo, you've been spreading that stuff again, haven't you "
I've had comfrey juice in the past for well over a year and still used it so I shouldn't really worry.

Told you the other day you worry too much...
