Read to the bottom of the blog to learn more about laying sod over the straw.

What Is Straw?

Straw refers to dry cereal grass stalks. Once you harvest cereal crops like wheat, barley, oats, rye, and rice, their grass stalks make straw. They are usually bundled in bales after drying, then used as mulch. Some people use them as animal feeds too.

Can You Lay Sod Over Straw?

Straw lacks nitrogen gas that aids in the decomposition process. It will, therefore, break down slowly hence making a moldy mess. This hinders the sod’s root germination process, which might kill your grass.

Sometimes, this straw contains seeds that might germinate and grow through the sod, damaging your lawn.

Although straw has several benefits for soil, it’s better to avoid laying sod over it. Instead, mix the sod with soil and level the area evenly when tilling. Wait for the straw to decompose for a few weeks, then lay your sod. This practice will result in a green and healthy lawn.

Can You Till Straw Into Soil Before Laying Sod?

Laying sod over straw might do more harm than good to your lawn. Therefore, mix it with the soil to boost its decomposition before installing grass. Once you put straw into the soil, bacteria and fungi immediately attack it.

The straw’s weight will gradually decrease, forming organic material that adds nutrients to your garden soil.

The straw breakdown process takes a few weeks or months. Therefore, wait at least one month after rototilling, then lay your sod.

Benefits of Straw

One of the greatest assets of soil is straw. Rototilling it to the soil before planting benefits the garden and plants in several ways. Read on.

1. Improves and protects soil structure

Leaving your garden bare subject it to nutrient leaching and soil erosion. So, incorporating straw in the soil protects beneficial microorganisms that make the environment healthy for growing crops. Additionally, it reduces soil erosion and makes your garden more nutrient-rich.

2. Provides enough moisture to plants

Moisture is an important factor for plants to grow. Straw locks in water for a long time. Therefore, it helps keep the soil moist, which benefits plants, especially during drought.

3. Maintains soil temperature

Straw acts as an insulator of the soil. It keeps the plants warm in cold weather, and in summer, it helps cool them. Its ability to regulate soil temperature results in greener and healthy plants.

Frequently Asked Questions (FAQs)

Q: Should you put straw on the sod?

A: It’s not advisable to put straw on sod as it can inhibit sod germination. Placing sod over straw means no contact between the sod and soil, essential for root development. Putting straw over sod will also damage your lawn, especially during removal.

Q: How long does straw take to decompose?

A: Straw takes a few months to decompose if you manage it well by rototilling it into the soil. However, it may take up to two years if you leave it unattended.


Although straw benefits your garden, laying sod over it is not a good idea. Straw breaks down slowly, thus slowing down the sod’s root development activity, which might kill your grass. Also, some straw seeds might germinate and damage your sod. Therefore, till your ground as you mix soil with straw. Wait a few weeks for the straw to decompose, then install your sod for better results.
