If you must poison the yard (my term for it) with something like RoundUp, instead of spraying, take a paintbrush and paint it on the leaves of what you want to kill. This technique is particularly useful if there's something that you want to save and encourage being choked out by something you want to kill. If you paint it on the leaves, you will kill what you paint it on, while preserving what you didn't paint it on. I used to do this in California to kill the blackberry bushes that were choking my rosebushes to death. It worked really well; I saved all the rosebushes and killed the blackberry bushes.

Now I am completely an organic gardener and don't use it at all, but this technique does work, and work well. Just be careful of how you paint, since RoundUp is a broad-spectrum broadleaf weed killer, and if you splatter too much, you'll also take out the parsley.
