2. Scotts Turf Builder Weed Feed5
Scotts Turf Builder Weed and Feed5 is a highly recognized product in lawn care, designed to eliminate weeds while simultaneously feeding your grass. For Zoysia lawns, it offers a way to address broadleaf weeds and provide essential nutrients for healthy growth.

The product is often described as reliable for routine lawn maintenance.
Trade-offs
While effective against many common weeds, this product may not be the strongest option for more aggressive or persistent weed species. Additionally, like all weed and feed products, it’s crucial to avoid using it on newly seeded areas or during extreme heat to prevent potential damage to the grass.
3. Roundup Weed Grass Killer₄ Pump ‘N
The Roundup Weed and Grass Killer with Pump 'N Go 2 Sprayer offers convenience and effectiveness for targeting unwanted vegetation. It's formulated to kill weeds and grass on contact, making it a go-to for quick cleanup.

Why I picked it
The integrated Pump 'N Go sprayer is a standout feature, offering a no-mix, no-spill application that significantly simplifies the process of weed control. This ready-to-use format makes it incredibly accessible for quick spot treatments or larger areas, especially for users who prefer not to deal with mixing chemicals.

Real-world experience

The convenience of the built-in sprayer is a major draw, allowing for precise application without the need for separate equipment. It’s often cited as a reliable choice for general yard clean-up.
Trade-offs
The primary trade-off with this product is its non-selective nature; it will kill any plant it comes into contact with. This requires careful application to avoid accidental damage to desirable Zoysia grass or ornamental plants. It is also an active herbicide, meaning it doesn't offer pre-emergent control for future sprouting weeds.

Trade-offs
Similar to other non-selective herbicides, it's crucial to avoid overspray onto desired Zoysia grass or other desirable plants, as it will harm them. Its action is contact-based, so it won't prevent new weeds from growing; it only kills existing vegetation.
5. Ortho Nutsedge Killer Lawns Ready-to-Spray1

For Zoysia lawns, this product offers a targeted approach to a particularly difficult weed.

It's praised for its targeted action and its ability to be used on Zoysia without causing damage when applied according to instructions.
Trade-offs
While excellent for nutsedge and other listed weeds, it's important to ensure that the weeds you are targeting are present on the product's label. Its specialized formula means it might not be as broad-spectrum for all types of weeds compared to more general-purpose herbicides.
How I picked
When looking for the best post-emergent herbicides for Zoysia grass, my focus was on effectiveness against common lawn weeds, safety for the turf itself, and ease of use for the homeowner. I evaluated products based on their active ingredients, the types of weeds they target, and user feedback regarding performance and potential for turf damage.
I considered products with formulations known to be selective, meaning they target weeds without harming the Zoysia grass. This involved looking at the chemical compounds in each herbicide and how they interact with turfgrass physiology. Speed of action and the length of control provided were also important factors, as was the clarity and practicality of the application instructions. I deliberately excluded products that required complex mixing ratios or specialized equipment unless the sprayer was integrated for ease.
Finally, I cross-referenced manufacturer claims with aggregated user reviews to gauge real-world success and identify any consistent drawbacks.
Buying guide — what actually matters for Best Post Emergent for Zoysia Grass
When you're choosing a post-emergent herbicide for your Zoysia lawn, knowing what to look for can save you a lot of guesswork and potential mistakes. It's not just about spraying something on the weeds; it's about selecting the right tool for the job that benefits your Zoysia's health.
What kind of weeds are you fighting?
Post-emergent herbicides are designed to kill weeds that have already sprouted. They come in two main types: selective and non-selective. Selective herbicides target specific types of weeds, like broadleaf weeds (dandelions, clover) or grassy weeds (crabgrass), without harming your Zoysia. Non-selective herbicides kill absolutely everything they touch, including your grass, so they’re best for spot treatments or clearing areas before reseeding.
For Zoysia, you'll generally want a selective herbicide.
Is it safe for Zoysia grass?
This is probably the most critical factor. Zoysia grass can be sensitive to certain chemicals. Always check the product label to ensure it explicitly states it's safe for Zoysia or warm-season grasses. Some herbicides that are great for cool-season grasses can injure or kill Zoysia.
Reading reviews and looking for products with a good track record among Zoysia owners can be very helpful here.
Application method: Ready-to-use vs. Concentrate
Post-emergent herbicides come in ready-to-use (RTU) sprays or concentrates that you mix with water. RTU options are super convenient, just grab and go. They often come with built-in sprayers, making application straightforward. Concentrates usually offer more coverage for the price and can be more economical for large lawns, but they do require accurate mixing with a separate sprayer.
For smaller lawns or ease of use, RTU is often preferred.
Active ingredients and their effectiveness
The effectiveness of any herbicide comes down to its active ingredients. For example, herbicides containing ingredients like 2,4-D, MCPP, and Dicamba are common for broadleaf weed control. For crabgrass, you might look for products with specific pre-emergent or post-emergent crabgrass killers. Researching what the key ingredients do and whether they're known to be effective against the weeds common in your area is a smart move.
Manufacturer specifications will usually outline what pests each product targets.
Timing and temperature considerations
Most post-emergent herbicides work best when weeds are actively growing and temperatures are moderate, typically between 60°F and 85°F (15°C to 30°C). Applying herbicides when it's too hot, too cold, or when rain is imminent can reduce their effectiveness or potentially harm your lawn. Always check the product label for specific timing and temperature guidelines.
Frequently Asked Questions (FAQ)
Can I use a post-emergent herbicide on a newly seeded Zoysia lawn?
Generally, it's best to wait until your Zoysia grass is well-established before applying any post-emergent herbicide. Most labels recommend waiting at least 4-6 weeks after seeding or sodding to ensure the new grass has developed a strong root system and can withstand treatment. Applying too early might damage or kill the young grass.
How long does it take for post-emergent herbicides to work on weeds?
The speed at which post-emergent herbicides work can vary depending on the product, the type of weed, and environmental conditions. Many herbicides begin showing visual results within a few hours to a few days, with weeds typically wilting and dying off within one to two weeks. Stubborn weeds might require a repeat application as per the product instructions.
Will post-emergent herbicides kill clover in my Zoysia lawn?
Many post-emergent herbicides formulated for broadleaf weed control are effective against clover. Products containing active ingredients like 2,4-D or MCPP are commonly used for this purpose. Always check the product label to confirm that clover is listed as a target weed and that the herbicide is safe for use on Zoysia grass.
How often should I apply post-emergent herbicides to my Zoysia lawn?
The frequency of application depends on the specific product and the weed problem. Some herbicides are designed for a single application, while others might require repeat treatments every few weeks, especially for persistent weeds or during peak growing seasons. Always follow the label instructions for reapplication intervals to avoid over-treatment and potential lawn damage.
Final verdict
For a consistently healthy and weed-free Zoysia lawn, Scotts Turf Builder Triple Action1 stands out as our top recommendation. It adeptly balances weed control with lawn fertilization and pre-emergent crabgrass prevention.
If you're looking for another excellent all-in-one option that focuses on broadleaf weeds and feeding, Scotts Turf Builder Weed Feed5 is a reliable choice as our top pick. For a budget-friendly and convenient solution for general weed killing, Roundup Weed Grass Killer₄ Pump 'N with its integrated sprayer is a solid performer.
