FAQs for lawn fertilization and treatment projects in Saint Charles, MO

The cost to reseed or overseed a lawn is about $1,050 on average, ranging from $450 to $1,700, depending on lawn size, seed type, and location. Popular seed types for residential lawns include bahia, fescue, and Bermuda. Keep in mind that it costs $0.10 to $0.20 per square foot to seed or overseed a lawn. Additional cost factors may include:

  • Fertilization: $80–$400

  • Soil testing: $700–$2,100

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

  • Treating weeds: $110–$325

  • Mowing: $50–$210

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

The frequency with which you should fertilize your lawn depends on its overall health. Healthy lawns with healthy soil may only need to be fertilized annually. On the other hand, you may need to fertilize lawns with shallow roots, poor soil, or neglected or over-fertilized every six weeks. To determine the best fertilizing schedule for your lawn, consider hiring a professional lawn fertilizing service and consult them about recommended frequency based on your lawn’s health.

Lawn aeration costs between $75 and $350 on average, depending on the size of the lawn, aeration type, slope of the lawn, soil type, lawn prep, and location. Keep in mind that it costs an average of $0.10 to $0.35 per square foot to aerate a lawn that’s less than 1,000 square feet. Different types of lawn aeration include: 

  • Spike aeration: $85

  • Core aeration: $200

  • Liquid aeration: $75

Whether organic or synthetic fertilizers are better for your lawn depends on your goals, budget, and plans for other lawn treatments. Organic fertilizer costs more but is likely to benefit your lawn more in the long run by improving the soil as well as feeding your grass. Synthetic fertilizers get faster results but don’t enrich the soil and may contaminate nearby bodies of water if you live on a shoreline. A hybrid fertilizer may be an option to give you the benefits found in both organic and synthetic fertilizers.
