What Is Sod? Types, Uses, and Growing Advice

Sod, also known as turfgrass, refers to grass that has been grown and cultivated specifically for transplanting. It provides an instant lawn that is densely rooted and ready for immediate use. Sod is a popular choice for establishing lawns quickly with mature grass.

What Is Sod and How Is It Grown?

Sod is composed of turfgrass grown on soil that is held together by the grass roots. It is cultivated on sod farms under optimal conditions to promote dense, healthy grass growth. The turfgrass is mowed short and allowed to develop a network of intermingled roots.

When the sod is mature and ready for harvest, it is cut into long strips or rolls with specialized sod cutting equipment. The slices of sod contain the grass blades along with a thin layer of soil known as the growth medium. This allows the grass to be transplanted quickly while preserving the intact root system.

Most sod is grown from seed, though some types may be propagated from sod plugs, sprigs, or stolons. Popular grass species used for sod include:

  • Bermudagrass – Widely adapted warm-season grass with good wear tolerance.
  • Zoysia – Slow growing warm-season grass known for its fine texture.
  • St. Augustine – Warm-season grass common in the southern United States.
  • Tall fescue – Cool-season grass suitable for northern regions.
  • Kentucky bluegrass – Versatile, cool-season grass that can thrive in many areas.

The right grass species is chosen based on climate and the intended use for the sod. Sod farm growers carefully control conditions like irrigation, fertilization, and mowing to encourage dense, high-quality turf growth before harvesting.

Why Use Sod?

Sod offers several advantages over starting a lawn from seed or other methods:

  • Immediate results – Sod provides an instant lawn that is ready for use as soon as it takes root, while seed takes several weeks to germinate and fill in.
  • Less effort – Sod only needs watering and mowing once established. Seeding a new lawn requires significantly more preparatory work.
  • Reduced erosion – The instant coverage from sod prevents soil erosion issues that can occur when establishing a lawn by seeding.
  • Higher success rate – Seeds are susceptible to birds, drought, and washing away, while sod is more likely to thrive under normal care.
  • Year-round installation – Sod can be laid in spring, summer, or fall as long as it is watered, while seed is best sown during certain periods.

The upfront cost of sod is higher than seeding, but the labor savings and reliable results make it an attractive choice for many homeowners and landscapers.

Using Sod for Lawns

Sod is commonly used for establishing new lawns, filling in bare or thinning areas of existing lawns, and replacing worn grass in high traffic zones or dog runs. When planning a lawn sodding project, it is important to:

  • Prepare the soil by removing debris, tilling, and grading it smooth.
  • Select a sod variety suitable for the climate and sun exposure.
  • Install during the right time period for the grass species.
  • Water sufficiently to establish deep sod roots, usually about 2 weeks.
  • Mow once sod takes root, keeping it between 2-3 inches high.
  • Follow proper sowing, fertilization, weed control, and mowing practices for the grass variety.

With proper installation and care, a sodded lawn provides an aesthetically pleasing, functional, and eco-friendly ground cover.

Using Sod for Landscaping

Beyond lawns, sod offers creative options for landscaping projects:

Groundcover – Use sod as a no-mow, low maintenance groundcover in place of mulch, gravel, or other materials.

Golf courses – Sod provides durable playing surfaces on greens, fairways, and tee boxes.

Sport fields – Athletic fields rely on sod for safe, resilient, and consistent turf footing.

Erosion control – Sod’s instant coverage helps control erosion on slopes, channels, and bare ground.

Roof gardens – Lightweight sod varieties work well for green roof systems.

Drainage areas – Sod holds soil in place along swales, ditches, and retention ponds.

With proper planning and care, sod can be integrated into diverse landscaping projects beyond just lawn installation.

Frequently Asked Questions

How long does it take for sod to root?

It typically takes 10-14 days for sod to root deeply enough after laying it for foot traffic and mowing. Proper watering during this period encourages root establishment.

How do I prepare the ground for laying sod?

Remove debris, loosen compacted soil, grade evenly, and water the soil before laying sod. Starter fertilizer and pre-emergent herbicide are also recommended.

What is the best time to lay sod?

Spring and fall are ideal seasons for sodding cool-season grasses. Warm-season grasses do best installed in late spring through summer. Sodding is possible year-round if properly watered.

How should I water new sod?

Keep soil moist but not saturated for 10-14 days. Water 3-4 times daily for 5-10 minutes to encourage deep rooting. Back off on watering as it establishes.

When can I mow and use new sod?

Once sod roots secure after about 2 weeks, it can be mowed at recommended heights and used normally. Avoid heavy use at first to prevent damage.

How much does sod cost compared to seeding a lawn?

Sod costs $0.30-0.70 per square foot on average installed. Seeding costs $0.05-0.20 per square foot but requires more labor. Long term costs are comparable.

Conclusion

For many homeowners, sod provides a reliable method to establish an appealing lawn rapidly. When cultivated properly at specialized farms, sod transplants well and achieves full rooting with adequate watering. Beyond lawns, sod offers creative options for landscaping solutions. With appropriate variety selection and care, sod can transform a property with beautiful, functional grass areas. For those seeking instant landscape results, sod is often the best solution.
