Question
Hey there Russel. I really couldn't find a category for my question so I picked you!  Aren't you lucky!  I have that boring but annoying problem with weeds growing between pavers.  I understand that many of the weeds (if the paving job was done right) are airborne vs from underneith.  Either way, I need to rid of them.  I just powerwashed my paved patio and now I need to ????  I need a product that will not hurt my 2 and 5 year old who play on the patio.   I've tried white vinegar but the color of the pavers changed a little and I'm afraid to eat away at them with further vinegar use. Good'ole salt works great but is too thin to brush easily. Is there a course salt on the market that I can brush in between the pavers easily?  Or, is that too damaging as well?  Thanks for your time!!!!!!!!!!

Answer
Hey, Diane.

I would not use salt. It creates its own problems, as you have found out.

Rather, use a pre-emergent weed killer, available at your local home improvement store. Follow the directions on the container. Usually you'll want to apply it when the weather is relatively warm and when it's not raining. If it rains within, I think, 24 hours, then you'll need to re-apply, but, again, follow the container instructions. Generally you'll want to keep children away for 24 hours, and since you do have children, use the liquid variety and not the granules. We don't want the little ones eating the stuff. I ate everything when I was their age, and we don't want them following in my footsteps. :)
