What to Look for in a Fertilizer

To find the best fertilizer for your lawn, there are key factors to consider, such as your soil test results, the product’s NPK ratio, and the micronutrients needed. Additionally, take into account the type of fertilizer you’re looking for and if the cost of the product meets your expectations.

Soil Test Results

A soil test helps you identify what the plant needs. Your soil test report shows soil pH, nutrient levels, and soil conditions. To find the best lawn fertilizer, get your soil tested. 

You need to know the soil’s nutrient deficiencies to select the best plant nutrients for your lawn. For example, if the test shows your soil lacks potassium, you can choose a fertilizer with a high potassium formula. Likewise, you can avoid nitrogen-heavy fertilizers if your soil has excess nitrogen.

Pro Tip: You can get a soil test from your state’s Extension service.

The NPK Ratio

NPK is the essential nutrient ratio present in the fertilizer, so that you can choose according to your soil needs:

  • Nitrogen (N) inspires deep green color and fast plant growth. Most lawn fertilizers are high in N. 
  • Phosphorus (P), also called phosphate, encourages deep, vigorous root development. It’s vital for new grass, but established lawns only need a little bit. Many fertilizers omit it entirely because P pollutes waterways, endangering aquatic life. Some states have banned phosphate fertilizers.
  • Potassium (K) improves grass’s tolerance to weather, pests, and diseases. Fall fertilizers typically contain more K than spring fertilizers, giving grass the strength to make it through winter. The K in fertilizer is sometimes called potash. For more information, check out our article: “What Does Potassium Do for Your Lawn?

Needed Micronutrients

In addition to the macronutrients nitrogen, phosphorus, and potassium, your grass also requires micronutrients to thrive. The standard soil naturally fulfills most micro needs, but if your soil test indicates an imbalance, you might want to choose a product that includes these nutrients. Examples include:

  • Calcium (Ca) strengthens grass’s cell walls, so lawns that lack calcium have trouble fighting off diseases.
  • Iron (Fe) aids nitrogen in giving grass its vibrant green color. Iron-deficient grass typically turns light green or yellow. 
  • Magnesium (Mg) helps lawns stay strong and healthy. Sandy soils are more likely to lack magnesium than loam or clay. Symptoms include discoloration and an increased sensitivity to pests and diseases.
  • Manganese (Mn) helps grass with nitrogen consumption and photosynthesis. Deficiencies are most common in sandy, alkaline soils. Signs included spotted or discolored grass blades. 

Types of Fertilizer

To choose the right lawn fertilizer for you, consider the following factors:

  • Liquid vs. granular: Liquid fertilizers are mixed with water and applied using a sprayer, while granular fertilizers are applied using a fertilizer spreader. When comparing liquids to granules, liquids are easier to apply and yield faster green-up. But granules release nutrients slowly for long-lasting results.
  • Slow-release vs. quick-release: Slow-release fertilizers gradually break down, feeding lawns for several weeks. They are cost-effective and require fewer applications. In contrast, quick-release fertilizers emit a quick burst of nutrition that greens-up grass fast. But the results are short-lived and too much fast-release nitrogen can burn grass.
  • Organic vs. synthetic: Organic lawn fertilizers typically cost more and yield slower results than synthetic fertilizers, but they are great for your lawn in the long run. Organic matter sustains your soil while being safe for children and pets. Keep in mind that some fertilizers have safe natural ingredients, but aren’t certified organic.

Additionally, some fertilizers come with herbicides or pesticides in their composition to provide a double (or even triple) action. These products typically contain one of the following:

Other special purpose fertilizers are tailored to suit the grass’s type or maturity:

  • Starter fertilizers are for newly established and freshly seeded lawns. Starter fertilizers have a lot of phosphorus to inspire dense root growth.
  • Grass-type precise fertilizers have nutrients that cater to a particular type of grass. For example, the best fertilizers for Bermudagrass improve pest and disease defense. And the best fertilizers for St. Augustine have enough nitrogen to support St. Augustine’s striking deep green blades. 

Cost of Fertilizer

Most retail fertilizer packages cost $25 to $70 and cover 2,500 to 10,500 square feet.

Liquid fertilizers typically cost more per square foot than granules, but liquids sell in smaller quantities that cost less. Additionally, liquid fertilizers usually have a good value for money since they have a good area coverage.

FAQ About Fertilizers

When Should You Fertilize Your Turfgrass?

The best time to fertilize your lawn depends on your type of grass: 

Cool-season grass: April, September, and November are the best times to fertilize cool-season grasses like Kentucky bluegrass, tall fescue, and fine fescue
Warm-season grass: April, June, and September are the best times to fertilize warm-season grasses like Bermuda, St. Augustine, Zoysia, and centipede

Should You Fertilize Your Lawn Before or After Rain?

Fertilizing your lawn right before or right after heavy rain can cause the fertilizer to wash away before sinking into the soil. Ideally, you should fertilize your lawn at least 2 days after heavy rain and when the forecast shows no rain for at least 2 more days. 

It’s OK to fertilize right before rain if you’re only expecting a light sprinkle, but you never truly know what to expect from Mother Nature. Use caution.

When to Call a Pro

With all that goes into selecting a lawn fertilizer, remember, that’s only half the battle. It takes proper equipment and heavy lifting to fertilize your lawn. And there’s much more to lawn care than just fertilization. That’s why LawnStarter links you to qualified lawn treatment pros with affordable services.
