Smelliest liquid feed imaginable...?

I can vouch for rhubarb leaves.
I can confirm that in my rudimentary experiment, it helps to keep cabbage whites away. However, this may be because there seem to be fewer around this year - either that or the smell is so bad it's repelling them for miles around.

I'm not joking - I've had people retching while I spray the stuff. It got on my legs when I was spraying the other day and my cat wouldn't come near me until I'd had a shower.

I think it's time just to post a reminder about home made pesticides from John, the site owner

Interesting comments about mixing various teas...

As I'm a bit limited for space on the plot, would it be a good idea to pour the four gallons of nettle tea in with the 6X liquid feed? Of course, I'll dilute it as suggested when I eventually use it (hopefully when there's nobody around...)

BTW, it's easy to make a basic filter for these jobs. Just take a plastic milk bottle, cut it in half, and fill the section at the top end with an old rag. (Obviously you don't want the round plastic top)! Hold it over your watering can or whatever, and decant the smelly/composty liquid though the rag! It takes out most of the debris, insects etc., that always gets into site-based receptacles like baths, tubs etc.

The comfrey round my plot is over waist high, so I'm looking to make some feed for the beans and tomatoes later in the summer... but this talk is making me dubious.

My entry for the smell contest is slug-filled beer traps. They were effective, but just not worth the torment of clearing them out.
