5 Best Liquid Lawn Fertilizers of 2025

A vibrant, healthy lawn doesn’t happen by accident. It takes the right care, and a quality liquid lawn fertilizer can make all the difference. Liquid fertilizers deliver nutrients fast, promote lush growth, and work well for all grass types. In 2025, the market offers plenty of options, but not all are created equal. After testing and researching, I’ve narrowed down the top five liquid lawn fertilizers to help you achieve that envy-worthy yard. This roundup review dives into each product’s features, benefits, drawbacks, and real-world performance. Whether you’re battling weeds, boosting greenness, or nurturing new grass, there’s a fertilizer here for you.

Let’s explore the best liquid lawn fertilizers and find the perfect one for your lawn care needs.

Why Choose a Liquid Lawn Fertilizer?

Liquid lawn fertilizers stand out for their ease of use and quick results. Unlike granular fertilizers, which need time to break down, liquids absorb directly into the soil and grass roots. This means faster greening and growth, often within days. They’re also simple to apply—just attach to a hose, spray, and you’re done. Plus, they’re versatile, working for everything from established lawns to new sod.

However, liquid fertilizers aren’t perfect. They require careful application to avoid burns, and their effects may not last as long as slow-release granular options. Still, for homeowners seeking convenience and immediate impact, liquids are hard to beat. Now, let’s dive into the top picks for 2025.

Top Liquid Lawn Fertilizers

1. Scotts Liquid Turf Builder with Plus 2 Weed Control, Liquid Weed Killer and Fertilizer, 32 fl. oz.

Overview

Scotts is a household name in lawn care, and their Liquid Turf Builder with Plus 2 Weed Control delivers a dual-action punch. This 32-ounce bottle combines a nitrogen-rich fertilizer with a weed killer targeting dandelions, clover, ground ivy, and more. Covering up to 2,000 square feet, it’s ideal for small to medium lawns needing both nutrition and weed management.

Key Features

• NPK Ratio: 29-0-3, high in nitrogen for vibrant green growth.
• Weed Control: Kills broadleaf weeds like dandelion, clover, and plantain.
• Coverage: 2,000 sq. ft. per 32 fl. oz. bottle.
• Application: Ready-to-spray, hose-end attachment for easy use.
• Grass Types: Safe for Bluegrass, Fescue, Ryegrass, Bahiagrass, Bermudagrass, Centipedegrass, and Zoysiagrass.

Performance

I tested this product on a lawn plagued by dandelions and patchy grass. The application was a breeze—connect the bottle to a garden hose, turn on the water, and spray evenly. Within three days, the weeds started wilting, and by day seven, most were gone. The grass greened up noticeably within 10 days, with a thicker, fuller appearance after two weeks. Users on Home Depot’s site echo this, with one reviewer noting, “The dandelions were curled up the next day, and the grass looks great!”

The high nitrogen content fuels rapid leaf growth, making it perfect for spring or early summer applications. However, it lacks phosphorus, so it’s not ideal for new lawns needing root development. I also noticed the sprayer can leak if not securely attached, a complaint mentioned by some Amazon customers.

Pros

• Kills weeds while fertilizing, saving time.
• Fast results—greener grass in under two weeks.
• Easy-to-use hose-end sprayer.
• Works on most grass types.

Cons

• Not suitable for St. Augustinegrass, Buffalograss, or dichondra.
• Sprayer may leak if not properly connected.
• No phosphorus for root growth.

Best For

Homeowners with established lawns battling weeds and seeking a quick green-up.

Where to Buy

Available at Amazon, Home Depot, Lowe’s, and Walmart. Prices range from $15 to $20.

2. Advanced 16-4-8 Balanced NPK – Lawn Food Quality Liquid Fertilizer by Simple Lawn Solutions (32 Ounce)

Overview

Simple Lawn Solutions’ Advanced 16-4-8 Balanced NPK fertilizer is a favorite for its well-rounded formula. This 32-ounce bottle covers up to 12,800 square feet, offering excellent value for larger lawns. Packed with organic ingredients like seaweed and fish emulsion, it’s designed for spring and summer use across all grass types.

Key Features

• NPK Ratio: 16-4-8, balanced for growth, root health, and resilience.
• Organic Additives: Seaweed and fish emulsion for soil health.
• Coverage: 12,800 sq. ft. per 32 fl. oz. bottle.
• Application: Requires a sprayer (not included).
• Grass Types: Works on Bermuda, St. Augustine, Zoysia, Buffalo, Centipede, Fescue, Ryegrass, and more.

Performance

I applied this fertilizer to a Bermuda grass lawn showing signs of stress after a dry spell. Using a backpack sprayer, I mixed the concentrate as directed and sprayed evenly. The grass perked up within a week, with a deeper green color and improved thickness by week three. A reviewer on Straight.com praised its ease of use and noted, “It provided our lawn with the key macronutrients it needed to stay healthy and green.”

The 16-4-8 ratio offers a great balance: nitrogen for foliage, phosphorus for roots, and potassium for drought resistance. The organic components also support long-term soil health. However, you’ll need a separate sprayer, which adds to the cost if you don’t own one. Some users reported slower results on heavily depleted lawns, suggesting multiple applications may be needed.

Pros

• Balanced NPK for all-around lawn health.
• Organic ingredients improve soil quality.
• Covers large areas, great for bigger lawns.
• Safe for all grass types.

Cons

• Requires a separate sprayer.
• May need multiple applications for stressed lawns.
• Slightly more effort to mix and apply.

Best For

Homeowners with large lawns or those seeking a balanced, organic-enhanced fertilizer.

Where to Buy

Available on Amazon and Simple Lawn Solutions’ website. Prices range from $25 to $30.

3. Scotts Liquid Turf Builder Lawn Food, 32 fl. oz.

Overview

For a straightforward fertilizer without weed control, Scotts Liquid Turf Builder Lawn Food is a top contender. This 32-ounce bottle covers 2,000 square feet and focuses on feeding grass with essential nutrients. Its simplicity and effectiveness make it a go-to for maintaining healthy lawns.

Key Features

• NPK Ratio: 29-0-3, high nitrogen for lush growth.
• Coverage: 2,000 sq. ft. per 32 fl. oz. bottle.
• Application: Ready-to-spray, hose-end attachment.
• Grass Types: Compatible with all grass types.
• Shelf Life: 3–4 years when stored properly.

Performance

I used this on a Zoysia lawn needing a quick boost before a backyard event. The hose-end sprayer made application effortless, and the grass looked noticeably greener in just five days. By day 10, it was lush and vibrant. Home Depot reviews align with this, with one user stating, “I noticed a change the same day! Two days later, it’s amazing.”

The high nitrogen content drives rapid greening, but like its weed-control counterpart, it lacks phosphorus for root development. Some Amazon users reported sprayer issues, such as uneven spraying or leaks, and a few noted fertilizer burn when applied in hot weather. To avoid this, apply when temperatures are below 85°F and water the lawn 24 hours beforehand.

Pros

• Fast greening, often within days.
• Easy application with hose-end sprayer.
• Works on any grass type.
• Long shelf life.

Cons

• No phosphorus for new lawns or root growth.
• Sprayer can be inconsistent.
• Risk of burn if applied in high heat.

Best For

Homeowners wanting a simple, fast-acting fertilizer for established lawns.

Where to Buy

Available at Amazon, Home Depot, Lowe’s, and Walmart. Prices range from $12 to $18.

4. Sunday Lawn Kickstart + Green Machine Liquid Fertilizer

Overview

Sunday Lawn Kickstart + Green Machine is a beginner-friendly option designed for lush growth and easy application. This bundle includes two 42.3-ounce bottles, each covering 5,000 square feet, and comes with a sprayer attachment. It’s perfect for homeowners new to lawn care or those seeking a hassle-free solution.

Key Features

• NPK Ratio: Not specified, but formulated for balanced growth.
• Coverage: 5,000 sq. ft. per bottle (10,000 sq. ft. total).
• Application: Hose-end sprayer included.
• Grass Types: Safe for all grass types.
• Extras: Lawn care app for personalized tips.

Performance

I tested this on a mixed-grass lawn showing uneven growth. The included sprayer attached easily, and the application took just 15 minutes. The grass started greening within a week, and by week three, it looked fuller and healthier. Sunday’s website highlights its user-friendly design, and customers appreciate the app, which offers tailored lawn care advice.

The formula balances quick-release nutrients for fast results and organic matter for soil health. It’s less potent than high-nitrogen options like Scotts, so it’s safer for new users but may not deliver dramatic results on heavily stressed lawns. Some users noted the bottles are bulky to store, and the price is higher than single-bottle competitors.

Pros

• Beginner-friendly with included sprayer.
• Covers large areas (10,000 sq. ft. total).
• App provides personalized lawn care tips.
• Safe for all grass types.

Cons

• Less potent than high-nitrogen fertilizers.
• Bulky bottles take up storage space.
• Higher price point.

Best For

New homeowners or those wanting an easy, guided lawn care experience.

Where to Buy

Available on Sunday’s website and Amazon. Prices range from $50 to $60 for the bundle.

5. Pendelton Turf Supply 18-3-6 Liquid Fertilizer (50% SRN & Micronutrients) (2.5 Gallons)

Overview

Pendelton Turf Supply’s 18-3-6 Liquid Fertilizer is a professional-grade option for serious lawn enthusiasts. This 2.5-gallon jug covers up to 30,000 square feet and includes 50% slow-release nitrogen (SRN) and micronutrients for long-lasting results. It’s designed for use throughout the growing season.

Key Features

• NPK Ratio: 18-3-6, balanced with slow-release nitrogen.
• Micronutrients: Supports plant health and root strength.
• Coverage: 30,000 sq. ft. per 2.5 gallons.
• Application: Requires a sprayer (not included).
• Grass Types: Safe for all grass types and ornamentals.

Performance

I used this on a large Fescue lawn needing consistent care. Mixed with water in a pump sprayer, it applied smoothly, and the grass showed improved color and thickness within two weeks. By week four, the lawn looked vibrant and healthy, with stronger roots. Homecapella.com reviewers noted, “The slow-release nitrogen kept the color vibrant, and the micronutrients helped with root strength.”

The 50% SRN ensures nutrients release over time, reducing the need for frequent applications. Micronutrients like iron and magnesium enhance overall plant health. However, the large jug is heavy, and mixing requires precision to avoid over-fertilizing. Some users found the instructions confusing, so double-check dilution rates.

Pros

• Professional-grade with slow-release nitrogen.
• Covers massive areas, ideal for large lawns.
• Micronutrients boost long-term health.
• Versatile for lawns and ornamentals.

Cons

• Requires a separate sprayer.
• Heavy jug is hard to handle.
• Instructions can be unclear.

Best For

Experienced users or those with large lawns seeking long-lasting results.

Where to Buy

Available on Amazon and Pendelton Turf Supply’s website. Prices range from $60 to $75.

How to Choose the Best Liquid Lawn Fertilizer

Picking the right fertilizer depends on your lawn’s needs and your goals. Here are key factors to consider:

1. Lawn Size and Coverage

Measure your lawn’s square footage to ensure the fertilizer covers the entire area. For small lawns (2,000–5,000 sq. ft.), Scotts or Sunday products work well. For larger lawns (10,000+ sq. ft.), Simple Lawn Solutions or Pendelton offer better value.

2. Grass Type

Most liquid fertilizers suit all grass types, but check the label. Scotts with Plus 2 Weed Control isn’t safe for St. Augustinegrass or Buffalograss, while others are universally compatible.

3. Nutrient Needs (NPK Ratio)

• Nitrogen (N): Promotes green, leafy growth. High-nitrogen options like Scotts (29-0-3) are great for quick greening.
• Phosphorus (P): Supports root development, ideal for new lawns. Simple Lawn Solutions (16-4-8) and Pendelton (18-3-6) include phosphorus.
• Potassium (K): Boosts drought and disease resistance. Look for balanced formulas like Simple Lawn Solutions or Pendelton.

4. Application Ease

Hose-end sprayers (Scotts, Sunday) are beginner-friendly. Concentrates (Simple Lawn Solutions, Pendelton) require a separate sprayer but offer flexibility for large areas.

5. Additional Features

• Weed Control: Scotts with Plus 2 Weed Control tackles weeds and fertilizes simultaneously.
• Organic Additives: Simple Lawn Solutions includes seaweed and fish emulsion for soil health.
• Slow-Release Nutrients: Pendelton’s 50% SRN provides longer-lasting feeding.

6. Budget

Prices range from $12 (Scotts Lawn Food) to $75 (Pendelton). Consider cost per square foot of coverage to find the best value.

Tips for Applying Liquid Lawn Fertilizer

To get the most out of your fertilizer, follow these tips:

• Water First: Water your lawn 24 hours before applying to reduce burn risk.
• Apply in Cool Weather: Avoid temperatures above 85°F to prevent stress on grass.
• Don’t Mow Right After: Wait 1–2 days after application to let nutrients absorb.
• Follow Instructions: Over-applying can burn your lawn. Stick to recommended rates.
• Clean Up: Sweep any fertilizer off driveways or sidewalks to avoid runoff.
