I know it's a great idea to cover the garden with a nice layer of mulch to keep moisture in and to discourage weed growth. My problem is, I don't have anything good to use. My compost didn't really break down over the winter, I don't have any trees (so no nice piles of leaves), and even if I did rake up grass clippings (which I don't as I understand it is better to leave them where they are) it would be a pathetic amount and not enough to nicely mulch the garden plot.
So, I am wondering what other good options there may be? I know some people use newspaper or cardboard. Is that safe... I mean from bleach used in the paper-making process, or from inks? What about black plastic or black "landscape fabric"?
Thanks very much for any pointers! I plant a garden every year but I still know very little about it, really.
