A healthy lawn starts with the right nutrients, which is why fertilizer is a key part of spring lawn care. Fertilizing in spring helps your grass recover from winter, grow thick and green, and build resilience against weeds and drought. The key is choosing the right spring lawn fertilizer—one that suits your grass type, soil, and local climate.
In this guide, we’ll help you choose the best grass fertilizer for spring so you can give your lawn the nutrition it needs to thrive all season long.
The Goal of Spring Lawn Fertilization
The Goal of Spring Lawn Fertilization
Why spring is the most important time to fertilize your lawn? because the grass kickstarts growth after a long, dormant winter. Fertilizing in spring provides essential nutrients that help your lawn recover, grow vigorously, and stay healthy throughout the season. Here are the main goals of spring fertilization:
Stimulating Growth: Grass is waking up from dormancy, so nitrogen—the key nutrient for growth—helps grass quickly develop lush blades and strong roots.
Improving Color: Nitrogen also enhances the green color of your lawn, giving it that vibrant, healthy appearance.
Strengthening Roots: Phosphorus helps build a strong root system, which is essential for long-term lawn health and drought resistance.
Boosting Overall Lawn Health: Fertilizer provides a balanced mix of nutrients to help your grass grow thick and outcompete weeds, improving overall lawn health.
How to Choose the Best Grass Fertilizer for Spring
Choosing the right fertilizer for your lawn starts with understanding its specific needs. Here’s how to make the best choice:
1. Which Side Do You Live On?
The climate plays a big role in determining the right fertilizer.
- Cool-season grasses thrive in cooler climates and are active in spring and fall. They need a fertilizer that supports early growth. Popular varieties include Kentucky Bluegrass, Perennial Ryegrass, and Fine Fescue.
- Warm-season grasses are best suited for warmer climates, with peak growth in the summer. These grasses, such as Zoysia, Bermuda, and St. Augustine, require fertilizers that support their growth during hotter months.
2. Determine the Type of Grass You Have
Identifying your grass type is essential for choosing the right fertilizer. Cool-season grasses need a higher nitrogen ratio for quick, early spring growth, while warm-season grasses benefit from fertilizers with a balanced nutrient mix for summer strength. If you’re unsure, check the label on your grass seed or consult local gardening experts for guidance.
3. Test the Soil on Your Lawn
Before choosing a fertilizer, test your soil to understand its nutrient and pH levels. Soil tests help you identify specific deficiencies, such as a lack of nitrogen or phosphorus.
You can use a DIY test kit for a general read on nutrient levels and pH.
For more detailed results, consider sending a sample to a local lab or university extension service.
4. Identify Any Lawn Problems
Pay attention to any visible lawn issues, such as yellowing grass, poor growth, or pest damage. These could be signs of nutrient imbalances:
- Yellow grass typically indicates a nitrogen deficiency.
- Thin or patchy grass may point to a phosphorus or potassium shortage.
- Weeds and diseases often thrive in under-fertilized lawns.
Types of Fertilizers
When selecting a spring lawn fertilizer, it's important to understand the different types available, as they all have unique features and benefits. Here are the most common types of fertilizers you’ll encounter:
1. Granular Fertilizers
Granular fertilizers are one of the most popular choices for lawn care. They come in both slow-release and quick-release formulas, providing flexibility based on your lawn's needs.
- Slow-Release Fertilizers: These fertilizers gradually release nutrients over time, feeding your lawn for several weeks or months. This is ideal for maintaining steady growth without the risk of overfeeding. It’s a great choice for spring when you want your lawn to have a consistent nutrient supply.
- Quick-Release Fertilizers: These deliver a rapid boost of nutrients and are ideal for immediate greening. However, they can cause a surge in growth that may require additional maintenance, such as more frequent mowing. Quick-release fertilizers are best used early in the season when your lawn needs an initial boost of energy.
2. Liquid Fertilizers
Liquid fertilizers are absorbed more quickly by the grass compared to granular forms, providing faster results. They are often used for fast greening or for spot treatment in problem areas. However, they require more frequent applications, as the nutrients are used up more quickly.
- Foliar Feeding: Liquid fertilizers can be applied directly to the grass blades, providing immediate nutrition. This is particularly useful for correcting deficiencies during the growing season.
- Concentrated vs. Ready-to-Use: Liquid fertilizers come in concentrated forms, which need to be diluted, and ready-to-use forms, which are easier but may be less cost-effective for larger lawns.
3. Organic Fertilizers
Organic fertilizers, made from natural materials like compost, manure, or plant-based products, provide a slow and steady release of nutrients. They improve soil health over time, increasing microbial activity and improving soil structure.
- Benefits: Organic fertilizers are less likely to burn the lawn and help build long-term soil fertility. They are great for those looking for an eco-friendly option.
- Drawbacks: They may not provide immediate results and often need to be applied more frequently.
4. Synthetic (Chemical) Fertilizers
Synthetic fertilizers are engineered to provide specific nutrients in precise amounts. They typically contain higher concentrations of nitrogen, phosphorus, and potassium, leading to quicker results.
- Benefits: Fast-acting and effective for quick growth, synthetic fertilizers are often more cost-effective for homeowners who want immediate results.
- Drawbacks: Overuse can lead to nutrient imbalances, soil degradation, and environmental harm if not applied correctly.

When and How to Apply Fertilizer Properly？
Proper timing and technique are essential for maximizing the benefits of spring fertilization. Let's break it down:
Best Times to Fertilize Your Lawn
A well-timed application ensures your lawn gets the nutrients it needs when it needs them most. Here's a seasonal breakdown:
- Early Spring: As the growing season begins, usually in late March or early April, fertilizing cool-season lawns jump-starts growth and enhances green color. This timing often coincides with applying pre-emergent weed control, such as crabgrass preventers.
- Late Spring: A second application replenishes nutrients consumed during the rapid early growth phase. For warm-season lawns, this is often the first feeding, as their active growth begins later in the season.
- Early Summer: This application strengthens the lawn against heat and drought stress.
- Fall: Fertilizing in autumn helps the grass recover from summer stress and store energy for winter dormancy.
Using slow-release fertilizers can reduce the frequency of applications without sacrificing results, offering a convenient alternative to traditional four-times-a-year schedules.
How to Apply Fertilizer Correctly
The application method can significantly impact the effectiveness of your fertilizer.
- Select the Right Tool:
- Use a broadcast spreader for large areas, providing even coverage.
- Use a drop spreader for small or precise areas, ensuring the fertilizer stays within boundaries.
- Follow Manufacturer Guidelines: Always adhere to the recommended application rate to prevent over-fertilization, which can burn the grass or encourage thatch buildup.
- Double Coverage: To ensure even distribution, apply the fertilizer in one direction first (e.g., north to south), then repeat at a 90-degree angle (e.g., east to west).
The Role of Watering in Fertilization
Watering after fertilization activates the nutrients and ensures they reach the root zone:
- Granular Fertilizers: Water lightly after application to help the granules dissolve and release nutrients.
- Slow-Release Fertilizers: Water consistently but avoid overwatering, which could wash away nutrients before they penetrate the soil.
Pro Tip: Less is More with Slow-Release Fertilizers
Slow-release formulas, like GreenView Fairway Formula Lawn Fertilizers, can feed your lawn for up to 12 weeks. With just two applications per year—one in spring and one in fall—you can achieve professional-grade results without frequent treatments.
Tips for Right Fertilizing Your Lawn
Fertilizing your lawn correctly is essential for its health and appearance. To help you achieve the best results, here are some practical tips to guide you through the process.
1. Apply the Right Amount of Fertilizer
Over-fertilizing or under-fertilizing can lead to poor lawn health. Applying too much can burn the grass, while too little won’t provide the necessary nutrients.
Always check the fertilizer label and your spreader's settings to ensure the right amount is applied. Make sure to spread the fertilizer evenly across your lawn to avoid patches of under or over-applied areas.
2. Water Your Lawn Before and After Application
Watering before and after fertilizing helps activate the nutrients and ensures they reach the root zone.
Water your lawn a day or two before applying fertilizer to ensure the soil is moist. After applying the fertilizer, water again to help the nutrients absorb into the soil. If it’s forecasted to rain soon, you can fertilize just before the rain, but ensure your lawn has been dry for at least 24 hours if the fertilizer contains weed control ingredients.
3. Avoid Fertilizing in Dry Conditions
Fertilizing during a dry spell can cause the fertilizer to sit on the grass surface, potentially burning the blades or failing to penetrate the soil properly.
Always fertilize when the lawn is moist, either through watering or rainfall, to ensure better absorption and effectiveness.
4. Consider Local Restrictions and Regulations
Some areas may have specific regulations on when and how you can fertilize, especially regarding phosphorus use, which can affect water quality.
Before applying fertilizer, check local guidelines to ensure you're following regulations, such as seasonal fertilizing restrictions or phosphorus usage limits.
5. Follow the Recommended Fertilizing Schedule
The best results come from a consistent, well-timed fertilization schedule.
For most lawns, spring, summer, and fall feedings are ideal. Avoid fertilizing during extreme heat, and be sure to fertilize before the grass enters dormancy in the winter.
Conclusion
Fertilizing your lawn in the spring is a critical step to ensure it grows healthy, lush, and green throughout the year. By understanding the type of fertilizer to use, applying it properly, and following best practices, you’ll set your lawn up for success. Remember, the key to a beautiful lawn is consistent care, timely feeding, and attention to its unique needs. With the right approach, your yard will thrive, becoming the envy of the neighborhood.
