Organic/Safe(?) weed killers - any recommendations?

Morning all,

Due to limitations on time, I am searching for an alternative way (then digging them out) to tackle the weeds on the paths of my allotment (namely those between the raised beds).

I was wondering if anyone could recommend any organic/safe weed killers which I can use to tackle these weeds. Also can I make any organic weed killers?

I am only considering this area and not on the areas where I intend to grow in currently - I will hand dig these weeds out.

I was also considering using newspaper mulch and bark chippings but I'm not sure if I can layer this directly over the weeds or if I have to kill them off/remove them first.

Thanks for your time in replying to me,

Samuel

 

Organic and animal safe: 1/2 cup of washing up liquid, 1 gallon of white vinegar, 1/4 cup of salt. Spray the weeds with it. May need a second spray in very "weedy" areas.
