plantmanager said:I have done this many times, but only in open spaces with no plants growing. I'm thinking it might not be good for plants already growing in the ground. They might be smothered and have a very hard time living.

Cardboard or newspaper will both work fine. I've used both. Just so long as rain gets to the roots. Huge sheets or cardboard from big boxes can be a problem.
