While hydroseeding is designed for bare soil, it is possible to apply it over an existing lawn with certain adjustments. For the new seed to be successful, it needs good seed-to-soil contact to germinate and take root. Without proper preparation, most of the new seed will fail to establish and will die. To hydroseed over existing grass, first mow the lawn as low as possible, then loosen and clear any exposed soil. It is also recommended to use a finer mulch mixture in the hydroseed spray, which helps the seeds penetrate the existing turf and reach the soil without suffocating the established grass.

The best time to plant grass seed depends on your local climate and whether you have cool-season or warm-season grass.

For cool-season grasses (like tall fescue), the ideal time to seed is late summer or early fall (typically August and September). During this period, the soil is still warm from the summer, but the air is cooler, creating optimal conditions for germination and root establishment before winter. There is also less competition from weeds. Spring is a secondary option, but cooler soil temperatures, the risk of a late frost, and less time for the grass to mature before summer heat can make it less successful.

For warm-season grasses (like St. Augustine), the best time to plant is from late spring through mid-summer (typically May and June), when temperatures are consistently between 75 and 90 degrees Fahrenheit.

In general, it is best to avoid seeding during winter or early spring, as cold soil and air can prevent seeds from germinating. For recommendations tailored to your specific grass type and climate, consider consulting a local lawn care professional.

The easiest way to rough up soil to accept grass seed and provide the best opportunity for its growth is to make several passes over the area with a garden tiller and rake away the loosened vegetation and debris. However, in some cases, very hard ground may require using a shovel or pick to break up pieces into smaller chunks that the tiller can handle more easily.

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
