How to kill paving weeds

Q: Which do you think is the best weedkiller for keeping paths, gravel and paving clean?


A: For paths and gravel I use nothing but glyphosate, since it has low toxicity and is neutralised on contact with the ground. My paving gets hand weeded because I have so many little treasures in the cracks. But if I spot isolated weeds that can be sprayed safely, I zap them, also with glyphosate.
