In every garden there are weeds. The trick is how to kill the weeds you hate without killing the plants you love. Or leaving a toxic residue that will seep into the earth or harm kids or animals. The answer is as simple as…
...pouring boiling water on them! Within a few hours, the plants will be dead, their leaves and roots shriveled up, brown and cooked. The hot water kills them from the inside out.

well the title of this post certainly caught my eye in my google reader. ;)
It's still pretty hard not to get the plants you want to keep, or to boil the entire tap root, which means they're coming back. For really large dandelions, there's apparently a system from Lee Valley that injects boiling water throughout the whole length of a tap root up to 2 foot underground, which intriques me, but I haven't tried it.
This works really well for ants. You just have to decide what you want more, to get rid of the ants or keep the grass the ants have built their home on.
This is probably a great solution for me, my brick driveway has weeds growing between the bricks and it's pretty unsightly . .
I have a length of thick pvc pipe- I think its like 22" long. I stick it in by the roots of the weed, pour boiling water into it and let it sit till the pipe cools down. Gets the hot water to the weed roots, pretty accurately! And my garden, the one I planted, doesn't suffer for it! Yay! I got the pipe at Home Depot for I think about $6. Make sure you get thick stuff so the water doesn't melt it!
