Weeds, and yet more weeds

What do people use to kill off weeds on a path and drive way?

I have tried a hot gun (blow torch) round up weed killer, plus a couple of other brands

Even this kiln dried sand with a weed killer in it

But they still return, almost on a weekly basis

I dont think there is anything I havent tried to kill em off

yes, I tend to agree with you snowdrops bleach is not the best idea I use roundup and it seem to last quite a long time I mix my own roundup I don't buy the ready-mix stuff mixed to the correct dilution it worked on both our block pavers and on the allotment although I know annual weeds will return sometime so they get another dose 

There is (or was) something called Pathclear which you applied with a sprinkler bar but not sure if it is available now. An alternative to bleach there is a hypochlorite solution which my neighbour uses. Good idea to find out if it breaks down after application into something less harmless to the environment.

Sorry I wont use bleach, just think of that going down the drain then into a water way/stream
I'd hate too think I have killed any wildlife off
I dont use tap water for my bird bath/drinker (its a bit big they come in for a bath)
There is even wasps coming in for a drink (I know its a bit late for them, but they are there)
But I could do with some more rain
So far the blow torch has worked
But because of the mild weather I think they will be back, all too soon

I looked for it, I found it, but decided against using it

How hard is it putting down a weed killer as long as you follow the instructions and wear glove and wash your hands afterwards

But this is a forum for amateur allotment gardeners, in the main. We ask people not to recommend professional use chemicals for amateur use.

No I wouldn’t use it either, & I very rarely use any weed killer or other chemicals. I tend to just use elbow grease & a sharp tool

I just use the round up spray bottles
If I was to use the back pack sprayer it wouldn’t use all the fluid in iyes round up is good but I still have weeds returning
But it doesn’t really work well if there is no sunlight and a bit chilly
