Straw is preferred to hay as a grass seed mulch because of its lower seed content. Straw is made of the stems of grass plants, while hay contains the stem plus the flowers and seeds. Still, straw will contain some amount of seed from farm grasses and weeds. These plants are undesirable in a new lawn. Removing the straw mulch from the grass seed sooner may lessen the amount of weeds that germinate, although most of the seed content has likely reached the soil in the first few days.
