How to Protect New Grass Seed From Erosion

Planting new grass seed is itself a form of erosion control, but planters must protect the newly sewn seed from erosion long enough for the grass to germinate and secure the soil. Rain, wind or runoff can remove seeds from the planting site as soon as you broadcast them over the area. Grass seed planted on slopes are especially susceptible to erosion. Covering the seed with a protective layer will help it become established.

Seedless straw
Erosion mats
Garden stakes

Instructions

- 1
  Rake a layer of soil over the seed as soon as you broadcast the seed. The thickness of the level of soil with which you cover the seed will vary with the species you select. Consult your local gardening center if you are unsure about the species of grass you plant. The soil layer is not usually thick enough to protect seed from complete erosion, but it does provide some protection.

  Cover the seeded area with 1- to 2-inch layer of straw. Select a seedless variety of straw so you do not introduce weeds into the planting site. The straw will allow air and water to reach the soil while holding the seeds in place.
- 3
  Lay erosion mats over the seeds if you are planting on a slope or an area of extreme erosion. Erosion mats are permeable and degradable, but are stronger than mulch. Lay the mats directly over the seeded area, then drive garden stakes through the mats into the ground to secure it in place. Use one stake every 2 to 3 feet.
