Lime on veg patch?

Our neighbour has suggested putting lime on our vegetable patch to keep down weeds, before doing this I would like some advice on the potential problems for crops and also our dogs – we have a 15 year old collie and 3 10 month old pups.

Any help will be much appreciated

Thanks for such a quick reply - must be local French folk lore - spuds are the main thing he wants to cover.

 
If I wanted advice on growing globe artichokes, a Frenchman would be the first person I asked.   But potatoes ........  !!!!!!!!!!!!!

Reason is, incidentally, that free lime in the soil causes Lime Scab on potatoes.  Quite a good name for it really.
