3 Best Weed and Feed for Zoysia Grass in 2025

Zoysia grass, with its lush, dense texture and remarkable resilience, is a favorite for homeowners craving a vibrant, low-maintenance lawn. This warm-season grass thrives in heat, shrugs off drought, and handles foot traffic like a champ. But even Zoysia needs a little TLC to stay weed-free and healthy. That’s where weed and feed products come in, combining herbicides to zap pesky weeds with fertilizers to nourish your lawn. Choosing the right one for Zoysia, however, can feel like navigating a maze. Not all products are safe for this grass, and some can cause discoloration or damage if misapplied.

In this roundup review, we dive deep into the best weed and feed for Zoysia grass, focusing on three top contenders: Scotts Turf Builder Weed & Feed3, Scotts Turf Builder Triple ActionI, and BioAdvanced 5 In 1 Weed and Feed. We’ll break down their features, pros, cons, and performance based on real-world testing, customer feedback, and expert insights. By the end, you’ll know exactly which product suits your Zoysia lawn’s needs, whether you’re battling dandelions, boosting growth, or preventing crabgrass. Plus, we’ll share tips on application, safety, and lawn care to keep your Zoysia thriving in 2025.

Why Zoysia Grass Needs the Right Weed and Feed

Zoysia grass stands out for its toughness, but it’s not invincible. Weeds like clover, dandelions, and crabgrass can invade, stealing nutrients and marring your lawn’s beauty. A quality weed and feed tackles these intruders while delivering essential nutrients like nitrogen, phosphorus, and potassium to promote thick, green growth. But here’s the catch: Zoysia is sensitive to certain herbicides. Products not labeled for Zoysia can cause yellowing, thinning, or even death. That’s why picking a Zoysia-safe weed and feed is critical.

The ideal product should:

• Control a broad range of weeds, from broadleaf nuisances to grassy invaders.
• Nourish Zoysia with a balanced NPK (nitrogen-phosphorus-potassium) ratio.
• Be easy to apply with clear instructions for homeowners.
• Minimize risks to pets, kids, and the environment when used correctly.

With these criteria in mind, let’s explore our top picks, starting with a detailed look at each product’s specs, performance, and suitability for Zoysia lawns.

Our Top Picks for Zoysia-Safe Weed and Feed

1. Scotts Turf Builder Weed & Feed3, Weed Killer Plus Lawn Fertilizer

• Coverage: 5,000 sq. ft.
• Weight: 14.29 lbs.
• NPK Ratio: 28-0-3
• Active Ingredients: 2,4-D, Mecoprop-p
• Weeds Controlled: Dandelions, clover, chickweed, plantain, and 50+ others

Overview

Scotts Turf Builder Weed & Feed3 is a household name for a reason. This granular product combines a potent herbicide with a high-nitrogen fertilizer to green up Zoysia lawns while wiping out common weeds. Its WeedGrip Technology targets both visible weeds and those lurking below the surface, ensuring long-lasting control. Safe for Zoysia, Bahiagrass, Bermudagrass, and more, it’s a versatile choice for warm-season lawns.

Performance

In testing, Weed & Feed3 delivers fast results. Homeowners report dandelions and clover wilting within days of application, with full weed kill in 1-2 weeks. The 28% nitrogen content sparks rapid greening, making Zoysia appear lush and vibrant. One 14.29-pound bag covers 5,000 square feet, perfect for medium-sized lawns. Users praise its ease of use with a Scotts spreader (set to 3 ¾ for rotary, 7 ¼ for drop).

However, timing matters. Apply when weeds are actively growing, and daytime temperatures hover between 60°F and 90°F. Wet the lawn first to help granules stick to weed leaves, and avoid watering for 24 hours post-application. Some users note temporary Zoysia discoloration under high heat, so stick to spring or early fall applications to minimize stress.

Pros

• Kills over 50 weed types, including tough broadleaf varieties.
• High nitrogen boosts Zoysia’s color and density.
• Covers 5,000 sq. ft., ideal for most suburban lawns.
• Easy to apply with clear spreader settings.

Cons

• Not safe for St. Augustine or Floratam grasses.
• May cause temporary Zoysia yellowing in extreme heat.
• Contains 2,4-D, a chemical with environmental concerns.

Best For

Homeowners with established Zoysia lawns seeking a budget-friendly, reliable weed and feed for spring or fall use.

2. Scotts Turf Builder Triple ActionI, Weed Killer and Preventer Plus Lawn Fertilizer

• Coverage: 4,000 sq. ft.
• Weight: 11.31 lbs.
• NPK Ratio: Not disclosed (high nitrogen focus)
• Active Ingredients: 2,4-D, Pendimethalin
• Weeds Controlled: Dandelions, clover, crabgrass, foxtail, and more

Overview

Scotts Turf Builder Triple ActionI takes a three-pronged approach: it kills existing weeds, prevents new ones (like crabgrass) for up to four months, and feeds Zoysia for thicker growth. Designed for Zoysia, Kentucky Bluegrass, and other grasses, it’s a great all-in-one solution for proactive lawn care. The inclusion of Pendimethalin, a pre-emergent herbicide, sets it apart from Weed & Feed3.

Performance

This product shines for its preventative power. Users report fewer crabgrass and foxtail outbreaks when applied in early spring, before weeds germinate. Broadleaf weeds like dandelions and clover die off within 1-2 weeks, while the fertilizer promotes steady Zoysia growth. The 11.31-pound bag covers 4,000 square feet, slightly less than Weed & Feed3, but its triple action justifies the trade-off.

Apply to a wet lawn when dandelions are active and temperatures are 60°F-80°F. Water in after 24 hours to activate the pre-emergent barrier. Some users mention mild Zoysia discoloration, especially on young or stressed lawns, so avoid applying during drought or extreme heat. The spreader settings (4 ¼ for rotary, 7 ¼ for drop) ensure even coverage.

Pros

• Kills and prevents weeds, including crabgrass, for up to 4 months.
• Strengthens Zoysia against heat and drought.
• Simple application with Scotts spreaders.
• Ideal for early spring use.

Cons

• Smaller coverage (4,000 sq. ft.) than competitors.
• Potential for temporary discoloration on Zoysia.
• Not suitable for newly seeded lawns.

Best For

Zoysia owners who want to tackle existing weeds and prevent future ones in a single application, especially in spring.

Safe for Zoysia, Bermudagrass, and Fescue, it’s a comprehensive choice for large lawns. Its slow-release fertilizer ensures steady nutrient delivery, reducing the risk of lawn burn.

Performance

This product excels in versatility. Its blend of pre- and post-emergent herbicides tackles over 200 weeds, from chickweed to wild onion, with noticeable results in days.

Users rave about Zoysia’s deep green color and thicker texture post-application.

Apply in spring, early summer, or fall when temperatures are 50°F-90°F and weeds are growing. Use a rotary or drop spreader for even distribution, and avoid watering for 24 hours. While generally safe, some users report minor Zoysia stress if applied during peak summer heat, so timing is key. The product’s chemical-heavy formula raises environmental concerns, but its efficacy is hard to beat.

Pros

• Long-lasting crabgrass prevention (6 months).
• Covers 10,000 sq. ft., great for large lawns.

Application Tips for Zoysia Weed and Feed

Applying weed and feed correctly maximizes results and protects your Zoysia. Follow these steps:

1. Time It Right: Apply in spring or early fall when weeds are growing, and temperatures are 60°F-90°F. Avoid peak summer heat to prevent Zoysia stress.
2. Prep the Lawn: Mow 1-2 days before and water lightly to wet the grass, helping granules adhere to weeds.
3. Use a Spreader: A rotary or drop spreader ensures even coverage. Follow product-specific settings (e.g., 3 ¾ for Scotts Weed & Feed3 rotary).
4. Follow Watering Rules: Don’t water for 24 hours post-application, then water lightly to activate fertilizers or pre-emergents (check product label).
5. Keep Pets and Kids Off: Wait until the lawn is dry (24-48 hours) before allowing access.
6. Read the Label: Confirm the product is Zoysia-safe and avoid overapplication, which can burn grass.

Pro Tip: Test soil pH before applying. Zoysia thrives at 6.0-7.0. If your soil is too acidic or alkaline, adjust with lime or sulfur for better nutrient uptake.

Safety and Environmental Considerations

Weed and feed products often contain chemicals like 2,4-D and Dicamba, which effectively kill weeds but raise concerns. These herbicides can harm aquatic life if washed into waterways and may pose risks to pets or kids if misapplied. To minimize impact:

• Sweep Up Spills: Brush granules off driveways or sidewalks to prevent runoff.
• Store Safely: Keep products in a locked, dry place away from children and pets.
• Consider Organic Alternatives: If chemicals worry you, try Espoma Organic Weed Preventer, though it’s less effective for Zoysia’s tough weeds.

Always wear gloves and a mask during application, and follow label instructions to the letter.

Common Weeds in Zoysia Lawns and How These Products Tackle Them

Zoysia lawns face invasions from:

• Dandelions: Broadleaf weeds with deep roots, killed by all three products’ 2,4-D.
• Clover: Nitrogen-fixing broadleaf, eliminated by 2,4-D and Dicamba.
• Crabgrass: Grassy weed, prevented by Triple ActionI and BioAdvanced’s pre-emergents.
• Chickweed: Low-growing broadleaf, controlled by all products’ post-emergent herbicides.

BioAdvanced’s Quinclorac targets grassy weeds better than Scotts’ offerings, making it ideal for mixed infestations. For stubborn weeds, a second application (after 6-8 weeks) may be needed, but don’t exceed two per year to avoid Zoysia stress.

Zoysia Lawn Care Beyond Weed and Feed

Weed and feed is just one piece of the puzzle. To keep your Zoysia lush:

• Mow Correctly: Keep blades at 1-2 inches, never cutting more than one-third at a time.
• Water Wisely: Provide 1 inch of water weekly, preferably in the morning.
• Aerate Annually: Relieve soil compaction to improve nutrient absorption.
• Test Soil: Check nutrient levels and pH every 1-2 years to guide fertilization.
• Overseed Sparingly: Zoysia is slow-growing, so overseed only to fill bare spots.

Pairing weed and feed with these practices ensures a thick, weed-resistant lawn that’s the envy of the neighborhood.

What Real Users Say

Customer feedback paints a vivid picture:

• Scotts Weed & Feed3: “My Zoysia went from weedy to green in two weeks. Dandelions are gone!” (Amazon, 5 stars). Some note, “Slight yellowing in July heat, but it recovered.”

These reviews align with our findings: all three products perform well when applied correctly, with BioAdvanced leading for large-scale weed control.
