I was afraid of that, but was curious if the rubber stuff would heat it up well enough to cook it. I'll go with the black stuff, I think it looks nicer anyway, maybe put a layer of leaves on top of the cardboard before putting down the mulch. I agree with the cardboard making it good soil again, sadly I'm afraid it'll take a long time till it's probably 'good' again. With how much roundup I've used on the ivy I'm afraid I've probably made it a toxic waste area! lol
By the way this is the product I've been using:

It's the Bayer Adv brush killer large tub with the built in sprayer. I've gone through 2 cans already but have another. You guys think it'll work or should I switch?
