I'm tired of weeding around my blueberries, which are inside some netting -- and thus are difficult to mow or weed-whack without knocking off the berries. In the past, I have used "mulch" and "weed-inhibitors" such as newspaper with grass clippings on top. This year, I also used corn husks on top of the newspaper.

I wondered if putting down cardboard around the plants might work. Though it might make it slippery when picking berries. Any suggestions?
