Lawn Fertilization and Treatment questions, answered by experts

St. Augustine is a hardy grass that’s relatively easy to grow, but it requires regular lawn maintenance to stay healthy. It’s best to keep up with a regular fertilization schedule during the growing season, plus a yearly dethatching to help it properly absorb air and moisture. Watering is also important, so be sure to water it enough to keep the soil moist.

On average, the cost of lawn fertilization is $250, ranging from $80 to $400, depending on the size of the lawn, its current condition, additional treatments, number of applications, fertilizer type, and location. Keep in mind that labor, tools, and equipment make up 80% to 90% of the total cost of lawn fertilization. Additional lawn treatment options include:

  • Lime treatment: $100–$150 per 1,000 square feet

  • Crabgrass treatment: $30–$80

  • Grub treatment: $30–$80

  • Mulching: $150–$400

  • Dethatching: $265–$295

Technically no, but they can look very similar and people often refer to the weedy grasses interchangeably. However, several differences keep these species separate. Crabgrass is often a darker color than carpetgrass and tends to sprout much earlier in spring. When allowed to grow out, crabgrass grows stems outward from the center of a stalk in a star-like pattern, which carpetgrass does not have.

Lime isn't a fertilizer. Instead, it helps fertilizers, plant food, and naturally occurring nutrients reach the grass by boosting the pH level in acidic soils. While adding lime isn't a crucial task in some locations, it's vital to keeping a lawn healthy in many areas. Lime's ability to encourage healthy grass by making nutrients in the soil more effective makes the task worth the effort, regardless of location.

Lawn care is tough work—even when you hire pros, there’s no guarantee your grass won’t die (unless, of course, your company offers a guarantee). But lawn care companies don’t control the rain or watering restrictions. Your type of grass also impacts the type of care required to keep a lush lawn—and how much that care costs. Talk to a lawn care pro to determine the best times to treat your lawn based on type of grass and your climate.
