Lawn Fertilization and Treatment questions, answered by experts

Yes—lawn renovation can turn your lawn from damaged to healthy in one month or less. You should also consider lawn renovation an investment in your home’s future. Not only will a lawn renovation ensure that you have a beautiful, healthy, and thriving lawn, but when it comes time to sell your home, the curb appeal will increase your home’s value.

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

A typical schedule may involve four to six treatments annually, but needs vary based on lawn conditions, weather, and maintenance goals.

If it’s been a few weeks and you haven’t seen anything pop up, double-check your seed packet and make sure you didn’t miss any steps. Did they need cold stratification (putting seeds in the freezer and then transferring to water before planting)? Do they have an exceptionally long germination period? 

 If you’ve followed all of the directions closely, you may just have had a bad batch of seeds. (Sadly, it happens.)

Herbicide application, manual removal, and landscape fabric are common approaches.
