Cost factors to fertilize a lawn

Cost factors to fertilize a lawn include:

  • Location – The cost of fertilizing services differs based on local demand, labor rates, taxes, and suppliers.

  • Climate – Warmer regions have extended growing seasons that may need 6 to 9+ fertilizer applications depending on the fertilizer type. Quick-release fertilizers also require more applications.

  • Fertilizer quality – The cost of fertilizer varies according to the brands and formula ingredients. Many types have weed-control additives mixed in.

  • LaborLandscapers charge $50 to $100 per hour for additional services.

  • Services – Combining fertilizing with other lawn care treatments costs less than fertilizing separately.

  • Application method – Landscapers with sprayers apply fertilizer much quicker than those using broadcast push spreaders, which affects labor costs.

  • Grass type – Some grass varieties need more nutrients than others.

  • Soil test – Lawn soil analysis costs $10 to $25 on average to measure soil pH and nutrient levels, which determines which fertilizer to use.

DIY lawn fertilizer and treatment prices

Lawn fertilizer costs $15 to $40 per bag of 20 to 40 lbs. that covers 2,000 to 5,000 square feet. A fertilizer push spreader costs $50 to $150 on average. DIY fertilizing saves money in labor. However, incorrectly applying fertilizer kills plants and causes illnesses to people and pets.

Lawn fertilization FAQs

Are lawn treatment services worth it?

Lawn treatment services are worth it from a skilled and dependable company. Offering convenient lawn care at a reasonable price saves people the time and labor of yard maintenance.

When is the best time to fertilize a lawn?

The best time to fertilize a lawn depends on the grass type and weather conditions.

  • Ground temperatures should be warmer than 55°F.

  • The grass should be in its active growing season.

  • Cool-climate grasses don’t need fertilizer during summer.

  • Winter fertilizing isn’t necessary.

  • Don’t fertilize before it rains because the treatment will wash off.

  • Wait a few days after it rains to fertilize when all puddles are gone.

  • Mow prior to fertilizing.

A lawn care professional will set up a seasonal fertilizer schedule that is appropriate for the climate and the grass type.

How often should I fertilize my lawn?

Most lawns need 4 to 6 fertilizer treatments per year, depending on the climate. Companies typically apply fertilizer treatments every 6 to 8 weeks.

Are lawn treatments safe?

Lawn treatments are safe for kids and dogs when used according to the manufacturer’s instructions. Pets and children should stay off the lawn for 24 to 72 hours after application. Even natural or organic ingredients can harm individuals if used improperly.

Where do landscapers buy fertilizer?

Landscapers buy fertilizer from landscape supply stores, hardware stores, and local fertilizer distributors. Bigger lawn care companies have access to specially formulated commercial products.

Should I aerate my lawn before fertilizing?

Yes, you should aerate your lawn before fertilizing. Aeration removes plugs of soil to open pathways for roots to absorb air, water, and nutrients. Otherwise, compacted soil suffocates root structures, making it harder for them to absorb fertilizer.

Getting estimates from lawn fertilizing companies

Before hiring a lawn fertilizing company near you, be sure to:

  • Consider at least 3 estimates.

  • Verify the company has a business license, liability insurance, and a surety bond.

  • Make sure they have fertilizer-application certifications.

  • Research online reviews on Google and HomeGuide.

  • Choose a company with at least 5 years of experience.

  • Check references.

  • Never give full payment until the work is complete.

  • Remember that low prices may be a sign of poor quality service.
