The average cost to seed or reseed a lawn is about $1,100, with prices typically ranging from $450 to $1,700. The final cost depends on factors like your lawn size, the type of seed used, and local labor rates. On a per-square-foot basis, you can expect to pay between $0.10 and $0.20.

Here are some cost estimates based on lawn size:

• 500 square feet: $50–$100

• 2,000 square feet: $200–$400

• 4,000 square feet: $400–$800

• 5,000 square feet: $500–$1,000

• 1 acre: $3,000–$5,880

• 2 acres: $6,000–$11,760

• 5 acres: $15,000–$17,640

Popular seed types for residential lawns include bahia, fescue, and Bermuda. Compared to installing sod, seeding is generally a less expensive option, especially for larger areas.

Additional services can add to the total cost:

• Fertilization: $80–$400

• Soil testing: $700–$2,100

• Yard cleanup and leaf removal: $200–$560

• Weed treatment: $110–$325

• Mowing: $50–$210

Choosing between sod and seed depends on your budget, timeline, and maintenance preferences.

Sod:

• Pros: Provides an instant, lush lawn and immediate curb appeal. It's more resistant to weeds and erosion, can be installed any time during the growing season, and offers a consistent appearance.

• Cons: Has a higher upfront cost, typically $0.90 to $1.80 more per square foot than seed. It offers fewer grass varieties and must be installed immediately upon delivery.

Seed:

• Pros: Less expensive upfront, making it a budget-friendly option. It offers a wider variety of grass types and is easier for a DIY installation.

• Cons: Takes much longer to establish, potentially up to two years for a full lawn. It requires more maintenance, including regular weed control, and is more difficult to cultivate.

Ultimately, if you want a beautiful lawn quickly and have a larger budget, sod is an excellent choice. If you are patient, want to save money, and prefer a wider selection of grass types, seeding may be the better option.

Yes, but the best approach is to apply fertilizer well before you actually sprinkle the seeds. Apply fertilizer with an NPK ratio somewhere around 10-10-20, or 10-10-10, depending on soil test results and the type of grass you're planting, about six to eight weeks before planting grass seed. This mix added to loosened soil will give the grass seed its best chance of getting off to a solid start. 

Power seeding and aeration are both excellent ways to improve lawn health, but they serve different functions. Aeration focuses on improving soil health by creating channels that allow more water, oxygen, and carbon dioxide to reach the roots. In contrast, power seeding is a method of planting grass seeds, often by creating narrow trenches in the soil. One service isn't better than the other; they are complementary. It is beneficial to aerate your lawn before power seeding, as this makes the seeding more effective by helping the germinating seeds access the resources they need. It's a good practice to aerate your lawn once or twice a year, regardless of whether you plan to power seed.
