Factors to Consider

how much straw to cover grass seedThere are various factors to consider when determining how much straw to cover grass seed with. These include the type of grass seed you’re using, the local climate, the time of year you’re planting, and the condition of the soil.

  • Type of grass seed: Different types of grass seed require different amounts of straw. For example, fine fescue requires less straw than Kentucky bluegrass.
  • Local climate: If you live in an area with hot, dry summers, you may need to use more straw to keep the soil moist.
  • Time of year: The best time to plant grass seed is in early spring or late summer/early fall. During these times, the soil is warm and moist, which helps the seed germinate.
  • Soil condition: If the soil is compacted or has a lot of clay, you may need to use more straw to help the seedlings break through the soil.

Bag of Grass Seed and Bale of Straw

Before you start planting grass seed, you’ll need to purchase a bag of grass seed and a bale of straw. Most local garden centers carry these items, so you shouldn’t have trouble finding them. When purchasing the grass seed, make sure to read the package directions carefully to determine how much seed you’ll need per square foot.

As for the straw, you’ll need enough to cover the entire area you’re planting. A good rule of thumb is to use one bale of straw for every 500-600 square feet of lawn.

Best Method to Cover Grass Seed

Best Method to Cover Grass SeedOnce you’ve spread the grass seed over the soil, it’s time to cover it with straw.

  1. Spread a thin layer of peat moss: This will help the seedlings absorb moisture and nutrients.
  2. Spread a layer of organic matter: This could be compost or well-aged manure.

    This will help improve the soil and provide the seedlings with nutrients.

  3. Spread the straw: Spread the straw in an east-west pattern, using a pitchfork to spread it evenly. Make sure the straw is spread in a thin layer – about ¼ inch deep.
  4. Water the area: Once the straw is in place, water the area thoroughly.

    This will help the straw settle and provide the seedlings with the moisture they need to germinate.

Potential Uses of Your Straw

Once your grass has grown strong and healthy, you may be wondering what to do with the leftover straw.

  • Mulch: Use the straw as a mulch around your garden plants to help retain moisture and keep weeds at bay.
  • Compost: Add the straw to your compost pile to help balance the nitrogen content.
  • Animal bedding: Use the straw as bedding for your livestock, such as chickens or rabbits.
