You want a weed killer that actually works across the board — not just on dandelions, but on the creeping charlie, clover, nutsedge, and poison ivy that ruin a lawn. The problem is most products are specialized: they kill one or two weed types but leave the rest standing. Finding a formula that truly covers all bases without destroying your grass is the real challenge.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent countless hours analyzing herbicide chemistry, application methods, and real-world results across dozens of formulations.
This guide narrows the field to the most effective, versatile options so you can stop second-guessing. My goal is to help you find the best all around weed killer for your specific lawn conditions and stubborn weed pressures.
How To Choose The Best All Around Weed Killer
A single all-purpose spray must balance selectivity (protecting turf) with potency (killing broadleaf weeds and brush). The right choice depends on the specific weed spectrum in your yard, your grass type, and your willingness to mix concentrates versus using ready-to-use formulas.
Know the Active Ingredients
The active ingredient determines which weeds die and which survive. Dicamba and triclopyr are powerhouse broadleaf killers, effective on clover, chickweed, and creeping charlie. Mesotrione adds pre-emergent action against crabgrass. Formulas with multiple active ingredients offer the widest weed coverage — look for blends rather than single-ingredient products.
Match to Your Turfgrass
Not all herbicides are safe on all lawns. Products with mesotrione work on Kentucky bluegrass, tall fescue, and centipede grass but can damage St. Augustine if overapplied. Dicamba-heavy formulas kill nutsedge but may harm bentgrass. Always check the label for your specific grass variety before spraying.
Concentrate vs. Ready-to-Use
Ready-to-use bottles are convenient for spot treatments but expensive per square foot. Concentrates require mixing with water in a pump or backpack sprayer but provide far better coverage and cost savings for large lawns. For an all-around product, concentrate forms give you more control over application rates.

In‑Depth Reviews
1. Ferti-lome Weed Free Zone (32 oz)
Ferti-lome Weed Free Zone is the gold standard for homeowners battling creeping charlie, thistle, and spurge. Its dicamba-based concentrate provides visible injury within hours and complete wilt in days, making it one of the fastest-acting selective herbicides on the market. The formula is safe on Kentucky bluegrass, Bermuda, bahia, and zoysia — covering the most common cool and warm-season turfgrasses.
Users report success on tough perennial broadleaf weeds that other products struggle with, including wild violet and oxalis. The concentrate dilutes significantly — a little goes a long way for spot treatments — but some reviewers found clover requires a slightly higher concentration than the label suggests. Adding a non-ionic surfactant improves adhesion, especially on waxy leaves.
This is a premium-tier product, reflected in the per-unit cost. For large lawns, the 32 oz bottle treats multiple applications without running out. If creeping charlie or thistle is your primary enemy, this is the most reliable weapon available. The speed of results and breadth of weed coverage justify the investment.
Why it’s great
- Kills creeping charlie faster than any competitor
- Safe on multiple common turfgrass varieties
- Concentrate format offers long-term value
Good to know
- Clover may need stronger mix than label rate
- Premium pricing compared to mid-range options
2. Roundup Poison Ivy Plus Tough Brush Killer Concentrate
Roundup’s Poison Ivy Plus formula is engineered for the worst invaders: poison ivy, poison oak, wild blackberry, kudzu, and woody brush. With triclopyr, fluazifop-P-butyl, and diquat dibromide working in tandem, it produces visible results in hours and remains rainproof in just 30 minutes — critical when unpredictable weather threatens your application.
The concentrate is designed for hose-end or tank sprayers, covering about 1,500 square feet per gallon of mixed solution. Users consistently report success on multi-year poison ivy patches and blackberry thickets that laugh at standard weed killers. The “hack and squirt” method — cutting stems and spraying directly into cuts — maximizes penetration on established vines.
This is a non-selective formula, meaning it will kill any plant it contacts, including grass. Use it in fences, trails, around trees, and other areas where you want total vegetation removal. The chemical strength requires proper PPE — respirator, gloves, and long sleeves are recommended by experienced users.
Why it’s great
- Fast visible results on brush and ivy
- Rainproof in 30 minutes
- Triple-active-ingredient formula for tough weeds
Good to know
- Non-selective — kills grass on contact
- Strong chemicals require protective gear
3. Liquid Harvest Mesotrione (8 oz)
Liquid Harvest Mesotrione offers a dual-action approach: it works as both a pre-emergent (preventing crabgrass seed germination) and a post-emergent (killing existing broadleaf weeds). The active ingredient mesotrione inhibits photosynthesis, causing susceptible weeds to turn white and die within 2-3 weeks. It targets 46 species, including crabgrass, clover, chickweed, and dandelion.
This concentrate is highly potent — a single 8 oz bottle treats a significant area when mixed at label rates. Users with centipede grass report excellent crabgrass control without turf damage, though St. Augustine requires careful application to avoid discoloration. The product needs activation: if no rain falls within 10 days of application, you must water in 0.15 inches to trigger the pre-emergent effect.
Because mesotrione can temporarily bleach or stunt healthy turf during heat or drought stress, it’s best applied in spring or fall when grass is actively growing. Adding a spray dye to the tank mix helps prevent overlapping and over-application. For homeowners managing both crabgrass and broadleaf weeds, this is a versatile single-bottle solution.
Why it’s great
- Pre-emergent and post-emergent in one product
- Safe on most cool-season and warm-season turf
- Highly concentrated — great value per application
Good to know
- Can temporarily bleach turf if overapplied
- Needs water activation within 10 days
4. Bonide Chickweed, Clover & Oxalis Killer (128 oz)
Bonide’s ready-to-use 128 oz spray combines dicamba and triclopyr to target chickweed, clover, oxalis, and dandelions without harming established lawn grasses. This is a selective formula designed for spot treatment on turf — perfect for homeowners who want to eliminate broadleaf weeds without killing the surrounding grass. The ready-to-use format means no mixing or measuring.
Users note that results take a few days to appear — clover typically browns within 72 hours, while dandelions vanish after a single spray. The formula is nearly odorless and clear, unlike some petroleum-based herbicides. Coverage is rated at 10,000 square feet per bottle, though several reviewers mention the included hand sprayer is inefficient for large lawns and recommend transferring to a pump sprayer for full-yard applications.
The main limitation: this product is not effective on nutsedge or crabgrass. It also requires calm weather and no rain for 48 hours after application. For homeowners dealing primarily with chickweed, clover, and dandelion patches, this is a solid, budget-friendly ready-to-use option. For larger infestations, the concentrate version would be more economical.
Why it’s great
- Ready-to-use — no mixing required
- Selective formula safe on most lawn grasses
- Large 128 oz bottle covers 10,000 sq ft
Good to know
- Hand sprayer is inefficient for big lawns
- Does not kill nutsedge or crabgrass
5. Ortho Max Nutsedge Killer Rtu (2 Pack)
Ortho Max Nutsedge Killer is a specialized product that targets yellow and purple nutsedge, kyllinga, wild onion, and garlic — weeds often missed by broad-spectrum herbicides. This ready-to-use formula requires no mixing and is rainproof in two hours, giving you flexibility in unpredictable weather. It kills weeds without harming Northern or Southern turfgrasses.
Users consistently report this as the only product that successfully eradicates nutgrass, especially when applied early — just as the weed breaks soil surface. The 2-pack includes two 24 oz bottles, enough for spot treatment over multiple seasons. For flower beds, reviewers recommend spraying carefully to avoid overspray on ornamentals, though the formula is designed to target the weed species listed on the label.
The main drawback: this is a one-trick pony. It does not kill broadleaf weeds like dandelions or clover. If nutsedge is your only problem, this product delivers. But for a true “all around” solution, you’ll need to pair it with a broadleaf killer. The ready-to-use format is convenient for small to medium yards but becomes expensive for large acreage.
Why it’s great
- Only product that reliably kills nutsedge
- Rainproof in 2 hours
- Safe on both Northern and Southern turf
Good to know
- Does not kill broadleaf weeds
- Small bottles — not ideal for large lawns

Final Thoughts: The Verdict
For most users, the best all around weed killer winner is the Ferti-lome Weed Free Zone because it combines the fastest knockdown on creeping charlie, clover, and thistle with turfgrass safety across multiple varieties.
