Did You Know?
1. Sod is indeed made of real grass, typically a type of grass called Kentucky bluegrass or fescue. The grass is grown on specialized farms and then harvested and sold as rolls or squares to be laid on lawns.
2. Sod was first introduced in the United States in the mid-1800s and quickly gained popularity over traditional grass seeding methods due to its convenience and ability to establish a lawn more rapidly.
3. Did you know that after being installed, sod requires about 1 inch of water per week to maintain its health and promote root growth? However, overwatering can actually be detrimental, as it may lead to shallow root development and increased vulnerability to diseases.
4. Sod can act as a natural air conditioner for surrounding areas, as it can significantly reduce the temperature of the ground compared to barren soil or pavement. This effect is particularly noticeable in urban areas with a lot of concrete and asphalt.
5. Sod has versatile uses beyond just lawns; it can be found on sports fields, golf courses, and even rooftop gardens, where its instant green coverage provides immediate aesthetic and environmental benefits.
What Is Sod And How Is It Used?
Sod, also known as turfgrass, is the upper layer of soil with grass growing on it that is often harvested into rolls. It is a popular choice for lawns, golf courses, and sports stadiums due to its ability to quickly establish a lush and uniform surface.
Sod is essentially pre-grown grass that is cultivated and nurtured on specialist farms. These farms are responsible for producing the sod rolls that are then transported to various locations for installation. The United States Department of Agriculture reported in 2009 that there were 1,412 sod farms producing a staggering 368,188 acres of sod.
One of the advantages of sod is that it can be harvested in different forms, such as small square or rectangular slabs or large rolls. The choice of form depends on the preferences of the buyer and the specific requirements of the project. Additionally, sod can be cultivated using hydroponic methods, resulting in a lighter and more portable product that is better suited for export.
The uses of sod extend beyond just creating picturesque lawns. It is commonly used for erosion control in areas where the soil is prone to being washed away. The root systems of the grass help stabilize the soil, preventing erosion and maintaining the integrity of landscapes. Sod is also a preferred choice for athletic fields, where its durability and uniformity are highly valued.
Different Types Of Grass Used For Sod Installation
When it comes to sod installation, different types of grass are used depending on the specific needs and climate of the area. Understanding the characteristics and growth habits of these grass varieties is crucial to achieving the desired outcome.
Some popular grass types used for sod include:
- Bermuda grass: commonly used on golf courses and sports fields in the southern United States. It is known for its resilience, ability to withstand heavy foot traffic, and its ability to stay green during hot summer months.
- Bluegrass: known for its lush appearance, fine texture, and cool-season adaptability, making it a popular choice for lawns in cooler climates.
- St. Augustine grass: often chosen for its ability to tolerate shade and salt, making it a suitable option for coastal regions.
- Centipedegrass: known for its low-maintenance requirements, commonly used in the southern United States.
Each grass variety also has specific cultivars that offer improved characteristics. For instance:
- Celebration Bermuda grass: a newer variety known for its exceptional drought and wear tolerance.
- Bella Bluegrass: boasts improved shade tolerance and disease resistance.
Remember to consider the specific needs and climate of the area when choosing the type of grass for sod installation.
The Process Of Growing And Harvesting Sod
The journey of sod begins on specialist farms, where it is meticulously grown to ensure a high-quality final product. These farms usually grow sod locally to minimize transport costs and reduce the risk of damage to the product.
To cultivate sod, the process involves several stages, starting with the selection of the appropriate grass seed. The selected seed is then sown in specially prepared soil beds, where it undergoes fertilization, mowing, watering, and vacuuming. This ensures optimal growth and development of the grass.
Sod is typically harvested 10 to 18 months after planting, depending on the specific grass variety and environmental conditions. During this time, the grass develops strong and healthy root systems that make it ready for transplantation.
Once ready for harvest, sod can be cut into small square or rectangular slabs or large rolls, depending on the intended use. This allows for flexibility according to the specific requirements of the project. The harvested sod is then transported to the desired location and laid on prepared soil, where it quickly establishes itself as a beautiful and functional surface.
Alternatives To Traditional Grass Lawns
While sod remains a popular choice for lawns, some homeowners and landscapers are exploring alternatives to traditional grass lawns. One such alternative is wildflower turf, which offers a more sustainable and low-maintenance option.
Unlike traditional lawns, wildflower turf requires less watering and fertilization. It consists of a diverse mix of wildflowers and grasses that create a naturally beautiful and biodiverse landscape. This alternative is not only visually appealing but also contributes to the restoration of natural habitats and supports local ecosystems.
Wildflower turf can be an excellent choice for those seeking to reduce their environmental impact. Whether it’s for residential gardens or public green spaces, wildflower turf provides an opportunity to create vibrant and ecologically beneficial landscapes.
Care, Maintenance, And Cost Comparison Of Sod Vs. Artificial Grass
Both sod and artificial grass require care and maintenance to ensure their longevity and attractiveness. However, the level of maintenance and associated costs differ between the two options.
Caring for sod involves a process that encourages growth, starting with proper watering, fertilizing, and regular mowing. Weeding is also necessary to keep the sod free from unwanted plants. While the initial installation of sod may require greater effort, with proper care, it can have an indefinite lifespan. However, resurfacing may be necessary every 10 to 20 years to maintain its appearance and functionality.
On the other hand, caring for artificial grass is relatively easier and requires less effort. It only requires occasional cleaning, which can be done with simple tools like a broom or hose. Artificial grass often comes with warranties and can have an average lifespan of 20 to 25 years, depending on usage and environmental factors.
In terms of cost, the installation of sod in a 50 square meter garden can range from £650-£750. This includes the supply of the sod rolls and the labor required for installation. The cost of artificial grass varies depending on factors such as self-installation or professional installation, the quality of the product, and the size of the area to be covered.
When making a decision between sod and artificial grass, it is important to consider not only the cost but also the level of maintenance and personal preference. While sod requires more effort to maintain, it offers the beauty and authenticity of natural grass. Artificial grass, on the other hand, provides a low-maintenance solution that can be installed almost anywhere.

Frequently Asked Questions
Is sod the same as grass?
While sod and grass share similarities, they are not exactly the same. Sod is essentially mature grass that has been grown and nurtured to be ready for immediate transplantation. Conversely, grass refers to the general term for plants belonging to the family Poaceae, which includes various species and varieties. In other words, sod is a specific form of grass that has been prepared for easy installation and rapid establishment, providing an instant green lawn solution.
Why is it called sod and not grass?
The term “sod” is used instead of “grass” because it has its roots in Middle Dutch and Middle Low German language, where it referred to “turf.” Its uncertain origin adds an intriguing element to the word, making it a unique and distinct term to describe the layer of soil and roots that is commonly used for lawns and landscaping. This linguistic journey from different ancient languages adds a touch of history and cultural influence to the term “sod,” setting it apart from the more commonly used word “grass.”
How long does sod last?
The longevity of sod depends on various factors, including the season in which it is ordered and installed. When sod is ordered during wintertime, it can remain viable on the pallet for approximately one week. However, the situation changes drastically during the hot summer months, as sod installed in such conditions is likely to last for no more than 24 hours or even less. The extreme heat and lack of moisture during summer accelerate the deterioration of sod, making it crucial to plan its installation accordingly to ensure optimal results.
Why do Americans call grass sod?
The term “sod” is commonly used in America to refer to grass because of its historical connection to Middle Dutch and Middle Low German. The word “sodde” came into use during the mid-15th century and is believed to have originated from these languages. While the exact origin remains uncertain, it is thought that the term may have been associated with water saturation, possibly related to the word “sog.” As language evolves over time, it is common for words to be borrowed and adapted, resulting in different regional variations. Hence, Americans adopted “sod” as a term for grass, reflecting the historical roots of the word.
