Lawn Food or Fertilizer: Which One Should You Choose?

If you’re in search of products to help your lawn flourish, you’ve likely encountered the terms “lawn food” and “fertilizer.” But do you know the difference between the two? Let’s dive in and explore the distinctions between them.

The Distinction Between Lawn Food and Fertilizer

In essence, fertilizers provide plants with the nutrients they require to thrive. Some manufacturers use the term “lawn food” to describe their fertilizer products. While plants actually produce their own food, the term “lawn food” refers to the nutrients necessary for their growth and nourishment. Hence, the confusion arises.

Understanding Lawn Food

To further complicate matters, some fertilizer manufacturers market their products as “lawn food.” Popular options on Amazon, such as Scotts Turf Builder Lawn Food and Miracle-Gro Water Soluble Lawn Food, reinforce the idea of feeding your lawn. However, upon closer inspection, you’ll discover that these products are simply fertilizers. They contain essential nutrients, like nitrogen, potassium, sulfur, and iron, which enable grass to create its own food, develop robust roots, and absorb nutrients effectively.

As a result, people often use the terms “lawn food” and “fertilizer” interchangeably. In reality, they refer to the same thing.

Determining When to Use Lawn Food or Fertilizer

If they’re essentially the same, you might wonder whether you should prioritize fertilizers over products labeled as lawn food. The answer lies in understanding the specific nutrient requirements of different plant varieties at various growth stages.

When starting a lawn, for example, grass requires more phosphorus to promote root development. Nitrogen is also necessary to maintain healthy growth. Therefore, it’s beneficial to use products specially formulated for new grass, like Scotts Turf Builder Starter Food for New Grass or GreenView’s Starter Fertilizer.

As your grass matures, it will benefit from additional nitrogen. Transitioning to regular fertilizers with a balanced nutrient ratio, like Lilly Miller All Purpose Planting and Growing Food or The Andersons Super Juice All-in-One Soluble Supplement Lawn Fertilizer, will provide the necessary nutrients for ongoing maintenance.

Lawn Food for Lawns, Fertilizer for Gardens

If you solely have a lawn to care for, choosing lawn food or fertilizer specifically designed for lawns is advisable. Lawn food, rich in nitrogen, caters to the primary needs of grass. Since grass does not produce flowers or fruits, it requires less phosphorus. Using lawn food ensures that every application is purposeful, avoiding excess phosphorus that could potentially pollute water sources.

However, if you have a garden with diverse plants, fertilizer is the better choice. Lawn food lacks the additional nutrients required by non-grassy plants, potentially leading to weakened growth or lack of blooming. Opting for fertilizers tailored to the needs of specific plants will provide the necessary support.

Environmental Considerations

Using the wrong type of fertilizer or lawn food for your garden can have negative environmental consequences. Excessive nitrogen and phosphorus can enter bodies of water, leading to oxygen depletion and the proliferation of harmful microorganisms. In some states, the use of phosphorus-based fertilizers is even prohibited due to water pollution concerns. It is crucial to use lawn food exclusively for lawns, where grass can utilize the nutrients without impacting surrounding water sources.

Unleashing the Potential of Plants

Understanding how plants derive their sustenance sheds light on their nutritional requirements. Through photosynthesis, plants synthesize carbohydrates using chlorophyll, sunlight, water, and carbon dioxide. While healthy soil generally provides adequate nutrients, replenishing them with fertilizers becomes necessary when soil depletion or other factors occur.

The Nutrients Essential for Plant Growth and Nutrition

Plants require several key nutrients to flourish. Nitrogen, phosphorus, and potassium are the major elements needed. Nitrogen is crucial for chlorophyll production, while phosphorus facilitates food production, root development, and blooming. Additionally, potassium helps plants combat stress and environmental challenges.

Secondary nutrients and micronutrients are also vital. Calcium fortifies plant cell walls, magnesium supports growth, sulfur aids in protein production and enzyme activation, and boron regulates nutrient absorption. Copper, chlorine, and iron contribute to reproduction, metabolism regulation, and chlorophyll formation. Other essential nutrients include manganese, molybdenum, zinc, and cobalt.

The Relevance of Fertilizers

While soil usually provides adequate nutrients, there are times when fertilizers are necessary. Factors like excessive watering, microorganisms, or soil exhaustion can deplete nutrients. For lawns, where rotation options are limited, fertilizers offer a practical solution to maintain nutrient levels.

Maximizing the Benefits: Additional Tips

In addition to nutrient supplementation, there are other aspects to consider when caring for your lawn.

  1. Timing: Mid-April, when soil temperatures reach 55 degrees Fahrenheit, is an ideal time for fertilization. Soil thermometers like the Taylor Precision Products Soil Testing Thermometer can aid in determining the appropriate time. Digital alternatives, such as the SensorPush Wireless Thermometer and Hygrometer, offer convenience and remote monitoring capabilities.

  2. NPK Ratio: Fertilizer packaging often displays three numbers representing the nitrogen-phosphorus-potassium (NPK) ratio. This ratio determines the nutrient composition of the fertilizer. For lawn care, nitrogen-rich formulations are typically preferred.

  3. Slow-Release Fertilizers: Options like the Milorganite Slow-Release Nitrogen Fertilizer ensure sustained nutrient release over several weeks. However, specific circumstances may call for fast-release or controlled-release fertilizers.

  4. Granules vs. Spray: While spray fertilizers offer convenience, granules provide more even application. Utilizing a spreader, either handheld or broadcast, ensures precise distribution.

  5. Scheduling: Fertilizing every six to eight weeks starting in mid-May and continuing until fall will support lawn health and prepare the grass for winter.

Understanding the appropriate nutrient ratios and aligning them with seasonal and climatic variations will help you achieve a thriving lawn. Remember, too much fertilizer can be detrimental, so exercise caution when applying.

By selecting the right formulation for your grass or plants, you can strike the perfect balance between providing essential nutrients and avoiding potential negative consequences. Whether you choose lawn food or fertilizer, you’ll be equipped to nurture a lush, healthy landscape.
