How to Get Rid of Yarrow
I've been trying to rid an area of my yard of an annoying weed. I've pulled it out many times, and recently broke down and put roundup on it, which I only do in extreme cases. I then covered it with those rubber tree ring things, and today when I looked, they're not dead!
At the grocery store today I saw someone actually paying good money to buy my weed. It appears I probably have yarrow.
If I cover the darn things with black plastic for a few weeks, will they die? Or, do I have to dig to China first?
Has anyone successfully gotten rid of yarrow? I'm finding small bits of it in the lawn =:(
