Can any of you please share remedies of killing weeds that grow in between pavers in a patio? I know I could use roundup, but there is a pond nearby with fish, frogs, birds, etc., so I would prefer to attempt some sort of organic solution. Any tips or success stories of remedies you have tried?

I think I've read of boiling hot water, maybe vinegar solution, ..., I guess I'm hoping to hear of tried-n-true remedies that have worked for you and hopefully the weeds didn't come back as crazy in subsequent years.

Thanks much!
