uberv There are products such as horticultural vinegar that will kill weeds without introducing nasty chemicals.

Michellina Zdraveski-van Loder Thanks Ruari and uberv, I'll have to google the horticultural vinegar as it's not something I've heard of but sounds very interesting. I use vinegar for everything around the house, so may as well try it in the garden. Our whole yard is going to be garden beds for vegetables, so we want the ground around them to be paths and gravel. I'd still be able to do the crazy paving with the gravel in between?
