• Granulate: $0.03-$0.06 per square foot of coverage. $1-$2 per pound or $10-$60 per bag.

Lawn Fertilization Pricing Factors

Besides just materials, you’ll need to consider these factors that influence prices, including:

• Climate & number of treatments.
• Services you choose. Combining fertilizer with other lawn care projects versus just doing the fertilization.
• Whether you do it yourself or hire a licensed and insured professional.
• Regional pricing differences.
• Quality of fertilizer.

Location 

Regional pricing differences can vary by up to 50% or more. What might cost you $30 in rural America might run $50 in higher cost of living areas like New York or San Francisco.

Number of Applications

Expect to pay two to three times as much in southern states compared to northern. In cold, northern climates, you might only need three applications while southern areas may need 6 to 10 applications with longer growing seasons and mild, short winters.

Xeriscaping

Xeriscaping your yard costs $2,000 to $14,000 but saves time and money in the long term. Xeriscaping, a type of yard designed to use little to no irrigation in arid climates, can both save you money and time. With less water usage and no lawn services, you can save $600 to $1,500 per year or more.

A few facts on xeriscaping:

• Americans use 45 to 70 gallons of water per square foot per year on their lawns. At an average of $1.50 per 1,000 gallons, you save $350 to $525 on water and $250 to $1,000 on fertilizing for an annual savings of $600 to $1,525.
• It'll both benefit the environment and reduce your water bill. With hardscapes and plants designed to thrive in dry conditions, you'll use less water.
• It reduces or eliminates the cost of fertilizing. Without fertilizer, there’s no runoff or freshwater pollution.
• It’s expensive to install, but inexpensive to maintain. Likely, you’ll make back your investment in a few years.

DIY vs. Hiring a Lawn Treatment Service

It’ll cost you half as much to do it yourself, or about $40 per 1,000 square feet if you do all the same treatments like a pro. However, a professional service usually gets better results, saves you time and makes sure all the applications happen on schedule.

For the best looking yard, hire a lawn care professional near you today.

Pros:

• The upfront price tag usually looks like twice as much, but once you factor in tools, chemicals and time, you hardly save any doing it yourself.
• Professional Results. Pros almost always get lusher, greener lawns than DIYers.
• Safe: If not handled properly, serious illness and property damage can occur. Professionals have been trained on how to apply fertilizer in a safe way and according to local and federal guidelines.

Cons:

• Upfront cost: Overall, you’ll pay slightly more than you would to do it yourself, usually about $100-$200 per year plus equipment.
