All lawns require nutrients to grow and thrive, but often there isn’t enough occurring naturally in the soil. The best lawn fertilizer for spring replenishes these nutrients and optimizes conditions for the main growing season. Generally, lawns should be fertilized at least twice yearly. Yet while the best time to fertilize lawns depends on the grass type and soil condition, almost all lawns can benefit from fertilizing at some point in the spring.

Not any random fertilizer will do the trick, however, and in fact there are many factors to consider when choosing a yard fertilizer. Lawn condition, environmental concerns, and fertilizer composition are all important considerations that will be explored ahead. Use this guide to read up on today’s top products plus essential shopping info so that you can nurture and maintain a lush, green yard.

Before You Buy a Lawn Fertilizer for Spring

When choosing a fertilizer for grass, it’s important to consider its potential for harm. Lawn fertilizers can have far-reaching effects on the environment and human health, including the potential to harm wildlife and contaminate groundwater. Some fertilizers are safer than others.

Lawn fertilizers can be broadly broken down into two categories depending on their ingredients: organic and chemical. Organic or natural fertilizers are directly derived from plants or animals. They can contain ingredients like alfalfa, cottonseed meal, seaweed, manure, or bone meal. Inorganic or chemical fertilizers are synthetically produced, often from mineral deposits.

The ingredients in organic fertilizer are often in a natural and minimally processed form, which means they take longer for lawns to absorb, while chemical fertilizers are already in a usable form and absorb more quickly. Organic options are generally safer than chemical fertilizers due to their natural ingredients and the fact that they don’t produce chemical runoff (although some runoff from organic fertilizers can also still be harmful). For either type, it’s crucial to always follow the directions on the usage label to reduce health and environmental risks.

It may be best to do a soil test to determine which nutrients the lawn is lacking before choosing a lawn fertilizer. (It’s usually necessary to test the soil about every 1 to 3 years, or more often, as needed.) The results allow folks to choose grass food with the nutrients their lawn needs, which can help reduce potential harm to the lawn and the environment.

How We Chose the Best Lawn Fertilizers for Spring

Natural lawn fertilizers come with several benefits, both for the soil and the environment. Their lack of synthetic ingredients means they don’t produce chemical runoff. Depending on the ingredients list, they can pose less of a risk to people and pets compared to chemical options. Plus, they benefit the soil in the long run, often lasting longer than chemical options and improving soil structure, water movement, and the health of soil microorganisms over time. For these reasons, we mainly stuck with organic lawn fertilizers for the top picks in this guide.

The ideal fertilizer formula will vary from lawn to lawn, so we prioritized other factors. We chose the best lawn-care products that are highly rated for their effectiveness and ease of use. Since fertilizing has to occur semi frequently, we also considered price, choosing a range of budget-friendly options.

Our Top Picks

A healthy lawn is key to curb appeal, but grass demands proper care to look lush and green. Wondering what fertilizer to use in spring? We’ve rounded up some of the best lawn fertilizers for yard maintenance.

Jump to Our Top Picks

Our Verdict

From one of the top brands in natural gardening products, our top pick is the Espoma Organic Lawn Booster lawn fertilizer for spring since it’s reliable, effective, and reasonably priced. It only contains nitrogen, however, so products like the Urban Farm lawn fertilizer or GS Plant Foods lawn fertilizer are other excellent options for lawns that need a more balanced fertilizer.

There are popular chemical fertilizers listed in some of our other fertilizer articles, such as Simple Lawn Solutions 16-4-8 and Scotts Liquid Turf Builder Lawn Food in our Best Liquid Lawn Fertilizer guide. However, as we choose more sustainable products, these are no longer recommended in our top picks due to their synthetic ingredients list. Instead, we’ve opted for all-natural fertilizers, which still come with some usage risks but are generally safer than most chemical options.

What to Consider When Choosing a Lawn Fertilizer for Spring

A walk down the lawn fertilizer aisle can quickly become overwhelming with the array of colorful bags and bottles promising a lusher lawn. Not every fertilizer is suitable for every lawn, and some may actually do more harm than good. To choose the best lawn fertilizer, there are a few main factors to consider, which include the soil composition, grass type, NPK ratio, formula type, and safety considerations.

Soil Composition and Growing Region

There is no one-size-fits-all fertilizer for every lawn, even for lawns within similar regions. Soil type, environmental conditions, and past care can affect the soil composition, which in turn affects lawn health. At least every few years, conduct a soil test to see which nutrients the soil is lacking. Soil tests will determine the amount of three key nutrients—nitrogen, phosphorus, and potassium—present in the soil, which makes it possible to choose the best lawn fertilizer accordingly.

The growing region will let folks figure out what type of grass makes up a lawn (if they don’t already know). In cold regions, cool-season grass varieties are common, while in hotter regions, warm-season grasses are more common. Each variety has different fertilization needs and ideal lawn fertilizer schedule, so follow recommendations according to the grass variety or specific grass types.

Regardless of the grass type, remember that any lawn should only be fertilized when it’s actively growing. Fertilizing a dormant lawn can have a negative effect—more is not always better when it comes to fertilizing lawns, and timing is just as important as the fertilizer ingredients and usage frequency.

NPK Ratio

Wondering what the lawn fertilizer numbers mean? All lawn fertilizers display an NPK ratio, which describes how much nitrogen (N), phosphorus (P), and potassium (K) the fertilizer contains. The NPK is written as three numbers, always in the NPK order and separated by dashes (N-P-K). Each number represents the percentage of each nutrient the bag contains. For example, a 20-5-5 bag of fertilizer will contain 20 percent nitrogen, 5 percent phosphorus, and 5 percent potassium.

These three nutrients are key to lawn health, but not every lawn needs the same amount. A wide range of different NPK ratios are available to suit the huge variety of lawn needs. Lawn fertilizers for spring can have a higher nitrogen concentration to boost lawn growth. For a new lawn, consider a fertilizer with a higher phosphorus content to nourish the root system. However, it’s ultimately best to choose a fertilizer according to the soil’s needs. Use the results of a soil test to determine the ideal NPK ratio for a lawn.

Granular vs. Liquid

Fertilizers come in granular or liquid form. Both are effective choices, but they each have their benefits and drawbacks.

Granular fertilizer comes in a dry-granule form and is applied by using a broadcast spreader. Many granular fertilizers are slow-release, so they may need fewer applications per year than liquid options (which means a lower-maintenance lawn). However, while granules are easy to apply and are beginner-friendly, users will want to take care to apply evenly. Granules can run a higher risk of burning the lawn if over- or unevenly applied.

Liquid fertilizer comes in a liquid or crystal form that is diluted in water and then applied with a sprayer. There are formulas that have low burn potential, plus liquids can be easier to apply evenly than granular options, so it’s easier to reduce the lawn burn risk. Liquids are generally faster acting, but that means they often require more frequent application and can be more affected by rainfall than granules.

Safety

Always follow all the usage directions with lawn fertilizer, which will recommend fertilizer concentration, tips to avoid runoff, and a time frame when the lawn is safe to use (which is especially important for homes with children and pets). Organic fertilizers can have a better safety profile than chemical options—read the usage label to check.

Though organic fertilizers contain natural ingredients, it doesn’t mean they can’t have harmful effects. For example, many organic fertilizers contain phosphorus, which is actually not a nutrient lacking in some lawns. Phosphorus runoff can contribute to algae blooms that harm water quality and aquatic life. The potential environmental impact is why it’s important to only use fertilizers as directed, and why it’s prudent to conduct soil tests and only use necessary fertilizers (for example, if a lawn doesn’t need phosphorus, find a fertilizer without it).

Tips for Using Lawn Fertilizers for Spring

The lawn fertilizers on this list are slow-release fertilizers (almost all the best organic lawn fertilizers are), which means they’ll take some time to show results. Unlike fast-release fertilizers, which can give immediate nutrition to the soil, slow-release fertilizers can take several weeks to take effect. However, this often means a more consistent result, less chance of overfertilizing or fertilizer burn, and longer wait times before applications. For lawns that need a quick pick-me-up, fast-release fertilizers can serve as an urgent treatment, though keep in mind that many fast-release fertilizers are synthetic and not organic.

Regardless of the fertilizer type, there are a few important tips to keep in mind before fertilizing a yard. A good lawn maintenance place should always start with a soil test (to be repeated every 1 to 3 years) to find out the soil composition and needed nutrients.

Once a fertilizer has been chosen, carefully read and follow the usage label directions. In general, avoid applying fertilizer before heavy or prolonged rainfall in the forecast. Light to moderate rainfall is all right (and even beneficial) since it can help the fertilizer seep into the soil.

Take care when applying to lawn edges and in sloped areas, where the fertilizer can run off into nearby waterways or sewers. If using granules, sweep up stray granules off of sidewalks, driveways, or patios to reduce runoff. Always allow for proper drying or absorption time before using or mowing the lawn.

  • Slow-release fertilizers are an excellent choice for lawn maintenance
  • Conduct a soil test before choosing a lawn fertilizer
  • Always follow the usage label directions
  • Do not apply fertilizer right before heavy or prolonged rainfall
  • Take steps to reduce the chance of fertilizer runoff, like not over-applying near lawn edges and sweeping up stray fertilizer granules from sidewalks

FAQs

Lawn fertilizers can replace lost nutrients in soil and contribute to a healthier and more beautiful lawn. From the fertilizer ingredients to usage habits and timing, there’s a lot to consider when choosing the best fertilizer to thicken grass and improve grass health and color. Read on for the answers to some frequently asked questions about spring lawn fertilizing.

Q. Is it better to seed or fertilize in the spring?

It depends. The best time to seed or fertilize a lawn will depend on your grass type, so search seeding and fertilizing schedules based on your chosen grass varieties. Most grasses can benefit from fertilizing in the spring. On the other hand, when it comes to seeding new grass, autumn tends to be a better time to seed cool-season grasses, and spring for warm-season grasses.

Q. How do I know if my grass needs fertilizer?

A soil test is the best way to find out. Soil tests are available for a low cost from gardening centers or local county extension offices. They often test the soil texture, pH level, and nutrient level, including levels of nitrogen, phosphorus, and potassium. Many soil test results will provide fertilizer recommendations for your lawn, taking a lot of the guesswork out of the process.

Q. How much lawn fertilizer do I need?

Follow the usage directions to determine how much lawn fertilizer you will need. The amount will vary from lawn to lawn, depending on your lawn size, soil composition, and the fertilizer formula. Most fertilizer products will display how many square feet of lawn they can cover, providing shoppers a better idea of how much they’ll need to buy.

Q. Should I put nitrogen on my lawn in the spring?

The surefire way to know if your lawn needs nitrogen is by administering a soil test. A soil test should be done every few years, though once a year is optimal. This will give you a better idea of if your soil is lacking in nitrogen.
