Landscape Seeding and Straw
When you have a newly graded lawn ready for seeding, it’s essential to take the proper steps. Wind and water can relocate newly planted grass seeds, so it’s important to protect them. For this reason, add a straw mulch over the top of your new grass seed.
Straw is the preferred cover for a newly seeded lawn for several reasons. Unlike Hay, it has a lower seed count, meaning there is less chance for weeds to show up in your new lawn. Second, until the new grass seed and newly germinated plants are established, they will die if allowed to dry out. Straw helps slow the evaporation of water from the soil and will keep it moist while the grass germinates.
