Rock Salt and lots of it. Just sprinkle it

Answer 5

I've used salt full strength on pesky weeds.  But even very salty water will do the same.

Yes, it takes a few weeks for the soil to regain its strength, for as long as it takes for the salt to leech out.  But the soil WILL be usable again.  

It's best to cut the weeds first (mow the yard) and let the salt get into the freshly-cut stems for faster absorbtion.  The weeds will turn yellow and brown in a day or two, and then you can pull out the weeds with ease.

But be careful will salt...it doesn't discriminate.

Answer 6

I would prefer boiling water or vinegar or both.

Answer 7

Salt and bleach will do the trick! But don't plan on growing anything in that spot for a while.

Answer 8

Soapy water !

That kills it

Answer 9

There's no mixing involved.  Just sprinkle from the container on a dry day.
