The Role of Fertilization in Lawn Health

GreenLife Services • February 24, 2024

Many homeowners struggle to get their grass to look green and healthy. You put in the effort, mowing, watering, and still, your lawn looks patchy and dull. Well, what if I told you the problem often comes down to one key step: fertilization. If you’re feeling frustrated about a patchy or dull lawn, don’t worry—this basic guide is here to help. We’ll break down exactly how to fertilize your lawn the right way, when to fertilize your lawn, and what fertilizer you need to use. Let’s dive in!

Why You Need To Fertilize Your Lawn

Grass needs essential nutrients, like nitrogen, to grow thick and green. Over time, the soil in your lawn can lose these nutrients due to natural processes and frequent mowing. Applying lawn fertilizer replenishes these lost nutrients, strengthens the turf, and improves its resistance to weeds and pests. So, yeah if you want to achieve the greenest lawn possible, you have to fertilize your lawn regularly!

When Should You Fertilize Your Lawn?

Time is also important when it comes to fertilizing your lawn. The best time depends on the type of grass you have:

Grass Type Fertilization Frequency Best Time to Fertilize
Cool-Season Grasses 3-4 times a year Early spring, late spring, early fall, and late fall
Warm-Season Grasses 2-3 times per year Late spring (after last frost), mid-summer, and early fall 
Tall Fescue 3-4 times per year Early spring, late spring, early fall, and late fall
Kentucky Bluegrass 3-4 times per year Early spring, late spring, early fall, and late fall
Zoysia Grass 2-3 times per year Late spring (after last frost), mid-summer, and early fall
Bermuda Grass 3-4 times per year (more frequently in warmer climates) Late spring (after last frost), mid-summer, and early fall
St. Augustine Grass 3-4 times per year Late spring, mid-summer, and early fall
Buffalo Grass 1-2 times per year Late spring (after last frost) and mid-summer
Fescue (Fine) 3-4 times per year Early spring, late spring, early fall, and late fall
Centipede Grass 2 times per year Late spring (after last frost) and mid-summer
Ryegrass (Perennial) 3-4 times per year Early spring, late spring, early fall, and late fall
Ryegrass (Annual) 1-2 times per year (used for overseeding) Fall (to help with winter coverage)
Bahiagrass 2-3 times per year Late spring (after last frost), mid-summer, and early fall
Carpetgrass 2-3 times per year Late spring (after last frost) and mid-summer
Seashore Paspalum 3-4 times per year Late spring, mid-summer, and early fall

How to Choose the Right Lawn Fertilizer

There are various types of fertilizers available, so it’s important to determine which fertilizer is best suited for your lawn:

Granular Fertilizer

This is the best fertilizer for beginners. It’s easy to apply and ideal for homeowners who prefer slow-release fertilization programs. This fertilizer releases nutrients over time, making it perfect for maintaining a healthy lawn with minimal effort.

Liquid Fertilizer

Liquid fertilizers work faster compared to granular fertilizers. This fertilizer is great if your lawn needs an immediate green-up before an event or gathering. However, this fertilizer requires more frequent applications. You can use a garden hose to spray these on your lawn.

Organic Fertilizer

Like its name, organic fertilizers use natural ingredients to feed your lawn and improve the soil. If you are an eco-conscious homeowner and you don’t want to use synthetic chemicals, then this fertilizer is perfect for you. Just like granular fertilizer, organic fertilizer works slowly so you don’t need to apply it too often.

Quick-Release Fertilizer

Quick-release fertilizers are the fastest among all fertilizers. But, you need to apply this fertilizer carefully to avoid fertilizer burn on your grass.

Check the Nutrient Ratio

When choosing a fertilizer, check the numbers listed on the fertilizer bag (e.g., 10-10-10). These represent the ratio of nitrogen, phosphorus, and potassium—key nutrients your lawn needs:

  • Nitrogen promotes lush, green growth.
  • Phosphorus supports strong root development.
  • Potassium improves overall lawn health and stress tolerance.

Pro Tip: Start with a soil test to find out what your lawn really needs. Most homeowners in Clarksville can get great results with a balanced fertilizer (e.g., 10-10-10).

If you want to use a fertilizer with a high quick-release component, you can use Cesco 46-0-0 Urea. It’s soluble and can be mixed with water and sprayed.

What You’ll Need to Fertilize Your Lawn

Before you get started, gather the following tools and supplies to make the process smooth and effective:

  • Fertilizer: Choose the right type for your grass and needs (e.g., granular, liquid, organic).
  • Spreader: A rotary (broadcast) spreader is best for evenly applying granular fertilizer. Handheld spreaders can also work for smaller lawns.
  • Garden Hose and Sprayer: If you’re using liquid fertilizer, you’ll need a hose and an attached sprayer for easy application.
  • Gloves: Protect your hands when handling fertilizer to avoid skin irritation.
  • Rake or Lawn Broom: To spread any fertilizer granules that may clump together.
  • Lawn Watering System: A sprinkler or garden hose to water the lawn after fertilizing.
  • Measuring Cup or Scale: To ensure you’re applying the correct amount of fertilizer as directed on the packaging.

How to Apply Fertilizer to Your Lawn Properly

If you don’t apply your fertilizer evenly you might get fertilizer burn. Follow these simple steps to fertilize your lawn properly:

Step-by-Step Fertilization Process

  1. Prepare Your Lawn: Mow the grass a day or two before fertilizing. Avoid fertilizing on overly wet or dry grass.
  2. Use a Rotary Spreader: Spreaders help apply granular fertilizer evenly across the lawn. Follow the settings recommended on the fertilizer bag.
  3. Close the Hopper: Before filling the spreader, make sure the hopper (the container) is closed to prevent spilling fertilizer in one spot.
  4. Start Around the Perimeter: Apply fertilizer around the edges of your lawn first to create a border, then move inwards using overlapping passes.
  5. Water Your Lawn: After applying the fertilizer, water your lawn immediately to help the nutrients absorb into the soil. Avoid heavy watering to prevent runoff.
  6. Clean Up: Sweep or blow any fertilizer that may have landed on sidewalks, driveways, or patios to prevent it from washing into drains.

Tips for Success

  • Always follow the instructions on the fertilizer packaging for proper application rates.
  • Wear gloves and wash your hands after handling fertilizer.
  • Store leftover fertilizer in a dry, cool place away from children and pets.

Common Mistakes to Avoid When Fertilizing Your Lawn

Applying fertilizer might seem straightforward, but many homeowners make mistakes that can harm their lawn. Here are some common pitfalls to avoid:

  1. Using Too Much Fertilizer : Excess fertilizer can burn the grass and damage the soil.
  2. Skipping a Soil Test : Without a soil test, you won’t know what nutrients your lawn needs.
  3. Uneven Application : Use a spreader to ensure the fertilizer is applied evenly across the lawn.
  4. Ignoring the Timing : Fertilizing at the wrong time can reduce the effectiveness of the fertilizer.
  5. Watering Incorrectly : Always water your lawn after applying fertilizer to help the nutrients absorb.

What to Do If You Spill Fertilizer on Your Lawn

Spilled fertilizer can cause patches of burnt grass in your lawn. If you accidentally spill fertilizer:

  1. Remove Excess Fertilizer : Use a broom or vacuum to clean up as much fertilizer as possible.
  2. Water the Area Thoroughly : Water the affected area to help dilute the excess fertilizer.
  3. Monitor the Lawn : Keep an eye on the area to ensure the grass recovers.

Taking quick action can minimize the damage and prevent long-term issues in your lawn.

Should You Hire Lawn Care Professionals to Fertilize Your Lawn?

Well, if you follow the steps mentioned above correctly, then you can just fertilize your own lawn.

FAQ 

Q. What is the best fertilizer ratio for lawns?

A. The best fertilizer ratio for lawns depends on your grass type, soil condition, and the season. A common balanced ratio like 10-10-10 or 20-10-10 works well for general lawn health. Perform a soil test to determine specific nutrient needs.

Q. What is the best time to fertilize the grass?

A. The ideal time to fertilize grass is early morning or late afternoon when temperatures are cooler. Seasonally, apply fertilizer in early spring for growth, mid-summer for maintenance, and early fall to prepare for winter.

Q. Do you apply fertilizer to wet or dry grass?

A. Apply fertilizer to dry grass, but ensure the lawn is watered lightly afterward. This helps the fertilizer soak into the soil and prevents burning the grass blades.

Q. How to use 13-13-13 fertilizer?

A. Spread 13-13-13 fertilizer evenly over your lawn using a broadcast or drop spreader. Follow the manufacturer’s recommended rate and water the lawn after application to help the nutrients absorb into the soil.

Q. What is better, 10-10-10 or 13-13-13 fertilizer?

A. Both are balanced fertilizers, but 13-13-13 provides slightly more nutrients per application. Choose 10-10-10 for routine maintenance and 13-13-13 if your lawn needs a nutrient boost. Always consider soil test results for precise nutrient requirements.
