This temporary, porous layer can help protect newly sown seeds. According to USDA plant physiologist Steven F. Vaughn, hydromulches typically contain water; a dye, so that crews can easily see where they’ve been; a mulch, such as wood fibers; and a binder, which is a compound that helps keep the mulch intact. In a series of laboratory tests, Steven and his colleagues have shown that half a dozen plant-derived compounds outperformed guar gum, a commonly used binder made by grinding bean
