Organic Weed Killer that works?

[NbyNW]

I've heard of people pouring boiling water slowly over dandelions that come up through the cracks in driveways and other paved areas. I think I tried it once, and I don't remember giving the weeds a second thought in a long while.

I use boiling water with a good helping of salt. you may have to repeat a time or two.. works for me

Goats?

And since I moved from Kudzu central to blackberry central - I can say with all confidence that the blackberries are WORSE because they are extremely painful. The thorns are like little barbed knives and they go right through heavy leather work gloves!

Goats might be practical in a field of blackberries, but for us urban gardeners with stone walls, I don't see how it would work because the blackberries will come right back.
I haven't heard any of the east coasters talking about poison ivy, which is invasive and VERY dangerous for some people. You can't even burn it, because the smoke is toxic (carries the itch stuff). I'd hate to have to deal with that. At least blackberries (the whole plant) are edible.

Mimi - I was totally kidding about the goats. Vinegar is way cheaper and doesn't require sturdy fencing.

I think the difference with poison ivy is that it generally grows in places with horribly cold winter temps that keep it from becoming kudzu/blackberry rampant. We did have poision ivy growing up the front of our tudor style house when I was a kid in Michgan. My dad had to pull it down and both he and I managed to get enough of the 'juice' on ourselves for a NASTY case of it. First and last time I've ever gotten a rash from it (thank goodness).
