Howdy folks, At the following URL is information on using "hairy vetch" as a natural mulch for your tomatos. Will also reduce your nutritive needs and the best part is that it's all natural. http://www.ars.usda.gov/is/tom/ ARS has a wealth of information for agricultural production. I just happened to stumble across this one while reading their online magazine. Even if you are in an area where hairy vetch isn't available, there are other vetch spp. I live on the line between zones 8 and 9 and have this stuff growing in my yard. Vetch is pretty common in cooler climes as well. I believe most of this research was done in MD, and it's a bit cooler up there than here in south-central Texas. Hope this is of use.
