Tomatoes perform best with regulated soil moisture. Mulch provides many benefits in the garden including maintaining moisture levels, suppressing weeds and moderating soil temperatures. Exposed soil may develop a crust on the surface from repeated wet then dry conditions. A crusty soil surface restricts air flow and inhibits water absorption. A layer of mulch can prevent the soil from crusting over.
Straw mulch is a popular choice for tomatoes. Avoid using hay as it introduces weed seeds. A thin layer (2-3 inches) of dry, herbicide-free, grass clippings can be used. If the lawn was treated with quinclorac (Drive), the clippings should not be used as mulch. (Cynthia Domenghini)
