Fertilizing 101: When, How, and What to Feed Your Lawn This Spring
A lush, green lawn doesn’t happen by accident—it needs proper nutrients to thrive! Fertilizing your lawn in spring is essential for promoting strong root growth, improving grass density, and ensuring a vibrant, healthy yard all season long. But when should you fertilize? What type of fertilizer is best? And how do you apply it correctly?
In this guide, we’ll answer all these questions, providing expert insights into fertilizer selection, application timing, and best practices to help you achieve the perfect lawn.
Why Spring Fertilization Is Essential
During winter, grass goes dormant and depletes its nutrient reserves. Spring fertilization gives your lawn the boost it needs to:
✅ Encourage strong root development for long-term resilience
✅ Green up your lawn faster after winter dormancy
✅ Prevent weeds by promoting thick, healthy grass
✅ Strengthen grass for summer heat and drought conditions
Skipping spring fertilization can leave your lawn vulnerable to weeds, thinning, and nutrient deficiencies, so getting it right is crucial.
When to Fertilize Your Lawn in Spring
Timing is everything! Applying fertilizer too early can lead to wasted nutrients, while fertilizing too late may not support healthy growth.
✔️ Best Time to Apply Spring Fertilizer:
⏳ Late April to early May – When the soil temperature reaches 10°C (50°F) and grass begins active growth.
🚫 When to Avoid Fertilizing:
❌ Too early (March or early April): The grass isn’t actively growing yet, so nutrients may be wasted.
❌ Too late (mid to late summer): The summer heat can cause fertilizer to burn your lawn.
Choosing the Right Fertilizer for Your Lawn
Not all fertilizers are created equal! The right choice depends on your grass type, soil condition, and lawn goals.
1. Understanding Fertilizer Labels (N-P-K Ratio)
Fertilizers are labeled with three numbers representing their nutrient content:
🔹 N (Nitrogen): Encourages green, leafy growth
🔹 P (Phosphorus): Strengthens root development
🔹 K (Potassium): Improves drought and disease resistance
For spring lawns, a balanced or nitrogen-rich fertilizer (e.g., 20-5-10 or 16-4-8) is recommended to encourage rapid greening and strong growth.
2. Choosing Between Organic and Synthetic Fertilizers
| Fertilizer Type | Benefits | Considerations |
|---|---|---|
| Organic Fertilizers (compost, manure, bone meal) | Improves soil health, slow-release nutrients, eco-friendly | Works gradually, requires more application |
| Synthetic Fertilizers (granular, liquid) | Quick results, precise nutrient balance, easy to apply | Can cause overgrowth if over-applied, may lead to runoff |
Best Option for Homeowners: A slow-release, nitrogen-rich fertilizer ensures steady grass growth without excessive mowing.
How to Apply Fertilizer Like a Pro
Now that you’ve chosen the right fertilizer, follow these expert tips for application:
✅ Step-by-Step Fertilizing Guide:
1️⃣ Mow Your Lawn First – This allows the fertilizer to reach the soil directly.
2️⃣ Choose a Spreader: Use a broadcast spreader for even coverage.
3️⃣ Apply on a Dry Lawn: Fertilize when the grass is dry to prevent clumping.
4️⃣ Water Lightly After Fertilizing: Helps nutrients absorb into the soil.
5️⃣ Avoid Overlapping Passes: This prevents over-fertilizing and uneven growth.
💡 Pro Tip: Always follow the recommended application rate on the fertilizer packaging to avoid burning your grass.
Common Fertilizing Mistakes to Avoid
🚫 Applying too much fertilizer – Can lead to fast, weak growth and increase mowing frequency.
🚫 Fertilizing before heavy rain – Nutrients may wash away before absorption.
🚫 Using the wrong type of fertilizer – Different grass types have different nutrient needs.
🚫 Skipping a soil test – Testing your soil helps determine which nutrients your lawn actually needs.
Spring Lawn Care: What’s Next After Fertilizing?
Once you’ve fertilized, follow these steps to maintain a lush lawn:
✅ Water properly – Deep but infrequent watering (1–1.5 inches per week).
✅ Control weeds early – Apply a pre-emergent weed control if necessary.
✅ Overseed thin patches – Helps fill in bare spots for a denser lawn.
✅ Mow at the right height – Keep grass at 2.5 to 3 inches to prevent stress.
Final Thoughts: Feed Your Lawn for a Healthy, Green Spring
Fertilizing in spring is one of the best ways to ensure your lawn looks lush, healthy, and weed-free all year. By choosing the right fertilizer, applying it at the right time, and following proper lawn care practices, you’ll set your yard up for success.
