What can I use as a mulch around my tomato plants?
Several organic materials can be used as a mulch around tomato plants. Suitable mulching materials include dry grass clippings, shredded leaves, straw, and pine needles. Do not collect grass clippings from lawns that have been treated with a broadleaf herbicide until the lawn has been mowed at least 2 or 3 times after the herbicide application. An application of 2 to 3 inches of material is usually sufficient.
