There is a very informative section on comfrey on site.(just print `comfrey` in the search box above).
I`ve looked at some youtube videos on the subject and only found one ( here- https://www.gardenersworld.com/how-to/grow-plants/how-to-make-a-comfrey-feed/)  that briefly mentions foliage feed. So, does anyone have experience of foliage feed.
 Not sure I would use it on my lettuce!

Foliage feeds work well, but comfrey is not going to be a popular choice with your neighbours (plot or house) as it really, really stinks   

Seaweed is a good one and does all leafy greens the power of good, but I would stick to just watering in the comfrey feed

Thanks newshoot.
I have trouble with mice eating the pea seeds so I`m trying a comfrey solution over the area sown. Neighbours will have to stay upwind for a while.

I made and used comfrey feed last year on most of my crops and had a great year - sweetcorn, squashes, chard - most things seemed to thrive on it. it is VERY smelly! So I make it in a 20 gallon bucket that has a close fitting lid. After a few weeks 'brewing, I then decant the liquid into an old 5 litre water bottle with a screw lid, and throw the mush onto the compost heap. I only noticed the smell when I opened the bucket lid to see how it was doing (and when decanting it - hold your breath............)
