Nothing ruins outdoor fun quite like bare, brown spots in your yard. A verdant lawn is a labor of love, needing hospitable soil for new growth and fertilization throughout its growing season. Maintaining a lush lawn can be quite the commitment for new and veteran homeowners alike.

We’ve spent over a hundred hours researching the top lawn care services for fertilization and the most trusted do-it-yourself (DIY) techniques. So whether you’ll be fertilizing your grass yourself or turning to professionals, here are the best lawn care services and fertilizer tips for a beautiful lawn.

Guide to Lawn Fertilization

It’s important to fertilize your lawn because grass can remove nutrients from the soil as it grows. Over time, this process leads to depleted dirt and decreased grass growth. Fertilizing a lawn can restore the pH and nutrient makeup of the soil in your yard.

Types of Fertilizer

First, you’ll want to select the type of fertilizer you’d prefer for your lawn. Fertilizers are made up of three primary elements: nitrogen (N), phosphorus (P), and potassium (K). The amount of each ingredient varies based on fertilizer type. The NPK value of a fertilizer displays the percentage of each element in the mixture. For example, an NPK value of 10-11-12 would contain 10% nitrogen, 11% phosphorus, and 12% potassium.

Common options for fertilizer are as follows:

Time of Year and Frequency

Factors such as where you are located, your grass type, your lawn’s health, and the condition of your soil will determine how frequently you should fertilize. Experts agree that fertilizing two to six times per year is ideal, often around mid-spring, Labor Day, and the end of October. However, a soil analysis is the best way to discover what your yard needs.

You’ll want to fertilize starting in the late spring if you have warm-season grass such as zoysiagrass, St. Augustine grass, or Bermuda grass. Start when the grass is already growing and continue through the summer months. Cold-season grasses, such as Kentucky bluegrass, ryegrass, bentgrass, and fescue grass, should be fertilized during the same window you start mowing in the spring. After the first application of fertilizer, you’ll want to pause until after Labor Day. Apply fertilizer through early fall, and then administer the final treatment by the midpoint of the autumn season.

Regardless of grass type, homeowners should stop fertilizing roughly six weeks before the first frost in your region, as fertilizing too close to winter can weaken your grass and soil throughout the cold months.

Spreading Fertilizers

No matter the type of fertilizer you choose, you’ll want an even spread of nutrients throughout your lawn. Fertilizers can be spread through several mechanisms:

The company’s convenient mobile app, wide variety of plans and á la carte services, and more than 40 years of experience impressed us as we researched available lawn care companies.

This provider also offers fertilizers for lawns, opting for naturally-based products wherever possible. In addition, it tailors its fertilizer shipments based on your region’s growing season.

Our Recommendation

If you elect to fertilize your lawn, remember to spread your fertilizer evenly, apply a treatment at least five times per year, and cater your lawn care schedule to your region and grass type. With a bit of planning and some time set aside, your grass will be thriving in no time.

If you’re repairing a brown, spotty yard or would rather have expert advice, we recommend TruGreen for fertilization and any accompanying aeration or seeding.

For DIY, subscription lawn care, we recommend Sunday for convenient and user-friendly products.

Frequently Asked Questions

What is a lawn fertilizer treatment?

To apply lawn fertilizer treatment, you will apply liquid or granular fertilizer into the desired area to provide essential nutrients to growing grass or plants. Grass fertilizer treatment typically consists of nitrogen, phosphorus, and potassium, but different types of plants or grass may require different formulas.

What is the best time to fertilize a lawn?

The best time to fertilize a lawn is in the spring. You may fertilize in March or April, depending on your region, while the soil is about 55 degrees Fahrenheit. You will want to fertilize three to four days after watering your lawn or a recent rainfall.

What are the benefits of fertilizing a lawn with a professional?

Some homeowners choose to fertilize their own yard, while others hire a lawn care service for a green lawn. The benefits of fertilizing a lawn with a professional include these:Fewer weeds: Fertilizers can assist in weed reduction through thickening grass and deepening roots. A professional service can also apply preemergent and weed treatments as needed.Healthy grass: Grass that has been fertilized properly can be less prone to disease, leaving your yard with fewer spotty or brown patches. Professional services can combine fertilizer treatment with lawn aeration for yards with tightly compacted soil to create a more hospitable environment for grass.Increased growth: Often, nutrients are unevenly dispersed throughout a lawn, leaving some areas healthy while others struggle to grow. Fertilizers can ensure that your grass is lush throughout by distributing nutrients into the entire yard. A lawn treatment professional can also provide overseeding for thicker, more luxurious grass.Safer soil: Thin grass can leave soil exposed to the elements, contributing to soil erosion, runoff, and depleted nutrients. Fertilized, thick grass with a deep root system will protect your soil’s nutrients and placement, leaving it healthier for years to come.Insect control: Thicker, fertilized lawns are more resilient in the face of outdoor pests, such as grubs. Professional lawn services can also offer pest control services for your lawn needs.
