Would RecommendPreen does a decent job of preventing weeds from popping up in my mulched flower beds. It acts by creating a barrier on top, so if you disturb the mulch (like rake it, or plant a new flower) be sure to put more Preen down.

It works.
Would RecommendI've used this before in flower beds and stones around the mailbox. I like that it doesn't kill the grass. And so far is working fine to keep the weeds away.
