Additional Considerations

How much does it cost to fertilize a lawn?

Fertilizing is an important step to a lush and healthy lawn. Soil provides grass with many of the nutrients it requires, but that typically needs to be supplemented with fertilizer, which also helps with new leaf, root growth, and can help reduce and control weeds. Fertilizing also replaces soil and grass nutrients that are lost from leaching or grass clipping removal, as well as helps the grass recover from traffic, wear, pest and animal damage. For this example, we’ll consider the cost of professionally fertilizing an average 8000 square foot lawn. Fertilizing average cost is $50-$80. Fertilizing can be done by a professional lawn care service or by the homeowner themselves.

It is recommended to start fertilizing a lawn in early spring (late February through March) and apply fertilizer every four to six weeks.

There are lots of options when it comes to choosing fertilizers. All fertilizers should have nitrogen (which helps with plant growth and development and coloring), phosphorous (for root growth, fruit, seeds, and flowers), and potassium (for root development and drought and disease resistance). These ingredients should be easily labelled on the packaging.

Before choosing a fertilizer, it is important that a soil test is performed. This can be done by a professional during the initial appointment, or it can be done by the homeowner with a DIY soil test kit available from a hardware store for $10-$25. A soil test determines the pH levels of the soil and determines how much fertilizer is needed, the goal is to have a pH level of 6.0 to 7.0. Most fertilizer packages have charts to help homeowners apply their pH level to see how much fertilizer is required and how often.

There are typically three choices to make: organic versus synthetic, liquid versus granular, and fast release versus slow release. Consider the following when choosing a fertilizer:

ProductProsConsBest UseCost (8000 sq.ft. lawn)

Environmentally friendly



Nutrients stay in their natural form

Improves soil form and soil’s ability to hold water and nutrients

Harder to over-fertilize plants

Effectiveness is limited seasonally

Nutrients aren’t released as quickly

Nutrient ratios are lower

Areas where children play or where food is grown or consumed$50-$95


Quick improvement

Produces the desired ratio of nutrients

Burns the skin

Made of non-renewable ingredients

Likely to leach

Repeated use can build up a large amount of toxic chemicals

Lower-traffic areas or places away from water drain-off$25-$80

Quick release of nutrients

Less expensive

Easy to clean

Nutrients may not last as long

Mixed with pesticides

High-profile areas of the lawn, such as a front yard$40-$65

More control on amount of fertilizer being released

Product releases slowly and for longer

More expensive

Often requires multiple visits to work completely

Areas close to water sources or gardens$60-$90
Fast Release

Nutrients are available right away

Stimulate fast growth

Don’t last as long

Leach nutrients from the soil

Lower-traffic areas$40-$60
Slow Release

Help uniform grass growth

Won’t burn grass or plants

Don’t need to be applied as often

More expensive

Might not work as well in the cold

Nutrients aren’t available right away

Require more irrigation

Higher-traffic areas$55-$85


Most lawn service companies charge a set priced based on the service provided and the size of the lawn. However, some lawn companies charge by the hour, with an average rate of $65 per hour.

Enhancement and improvement costs

  • Lawn aeration 1 costs $120-$150 on average and should be done two to three times per year. This is done with an aerator that pulls up plugs of the dirt and grass throughout the yard and makes the grass more receptive to fertilizer and treatments, builds stronger roots, makes the grass more tolerant to extreme temperatures and conditions, and decrease water runoff. It can be done on your own by renting an aerating machine for $40-$60 per day.
  • Grubs 2 are small insects that feed off the roots of grass and typically appear in the late summer to early fall. A DIY grub 2 treatment can be purchased for $20-$30 that is then spread over the affected areas. Professional grub control service typically costs $60-$75. Grub 2 treatment typically only needs to be done once a year.
  • Adding lime to the lawn raises the pH level and can help improve the appearance of the grass. It is typically applied in the fall and comes in small pellets. A large bag of lime averages $10-$25 for DIY treatment, or a professional can add the supplement for $60-$75.

Additional considerations and costs

  • Many professional lawn care companies offer a discount when you sign up for a regular service, such as fertilizer application every four to six weeks. Other packages include annual offerings, including a seasonal fertilizer and aeration treatment.
  • Adding crabgrass 3 treatment costs an additional $75-$150. Weed treatments cost an additional $75-$150 for a common spray or powder application.
  • Applying your own fertilizer is obviously significantly cheaper, but using a professional lawn service brings with it the professional opinion and typically comes with better results. Many professionals use fertilizer that is slightly more powerful that can work faster and last longer. Using a professional service can also create a safer atmosphere, especially with synthetic fertilizer 4, as you are not exposing yourself to the chemicals without proper protection.

1 Lawn aeration: The process of putting small holes into a lawn to break up compacted soil so that air, water, and nutrients can more easily reach the roots of the grass, allowing them to grow deeper
glossary term picture Grub 2 Grubs: The larva of a beetle. While the adult beetle poses little threat to a lawn, the grubs can ruin a lawn by feeding on the roots of the grass
glossary term picture Crabgrass 3 Crabgrass: A type of unwanted grass found in lawns. It keeps growing and spreading seed throughout the warm season, which makes it difficult to kill
4 Synthetic fertilizer: An inorganic, chemically-derived, substance applied to soil/plants to increase soil fertility and aid plant growth
