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............)

I would also recommend the comfrey feed. Yes it is smelly but I brew mine in a water butt with a tight fitting lid. That way There are no escaping odours!. Yes you can smell it coming out the tap but it is dilute at this point. I push the leaves into an old pillow case and tie the top usually with a long piece of twine trapped  in the top so it's easy to haul out the pillow case at the end! I brew it for at least 6 weeks

Good luck

I wouldn’t put any kind of foliage feed on tomatoes due to blight risk. In fact I’ve been reading up on fertiliser type and blight, and apparently high nitrogen feeds are not recommended as they cause a lot of rapid leaf growth, which increases risk of blight. Comfrey feed is supposed to be high nitrogen, although I’m not sure how much it actually contains ( it must depend on the recipe used) and if it is as much as commercial feeds. I’m not going to use it as freely in my toms this year as I did last year.

Just checked my thinking and RHS confirms Comfry is high in potash not nitrogen so is basically similar to commercial tomato feed but probably not as consistent. Been using it for a number of years on tomatoes and other greedy crops like squash and courgette but just at ground level. Have used on foliage of spuds but not at all on fruit as found it tainted taste of strawberries and not risking others and not where growing guidance says don't get foliage wet, like toms. It does smell but not too bad once diluted
I've read about nettle tea which is high in nitrogen and good to develop leaves but never used. Was thinking for cut flower patch ?

 "push the leaves into an old pillow case and tie the top usually with a long piece of twine trapped  in the top so it's easy to haul out the pillow case at the end!"  Thanks for that tip Twood. I`ve been looking on the info pages here ,for feeding cucumbers and soaking new horse manure was a suggestion with using a hessian sack. An old pillow case could save me buying one.

Glad to be of help 
In answer to a mention of brewing nettles. I do this on a slightly smaller scale depending on how many nettles I can get and use it on the cucumbers as its high in Nitrogen which is what they require unlike the tomatoes

Thanks for this information @Learnerlady. I have checked out the RHS page in natural fertilisers and it is reassuring that comfrey is not high in N.
