9 Best Dandelion Spray | Kills Weeds, Saves the Grass

A 128-ounce refill that treats 5,000 square feet without the premium price tag.

This is the value king for big yards, delivering 128 fluid ounces — a full gallon — of concentrate designed to refill your existing Comfort Wand applicator. It covers 5,000 square feet, which is roughly five times the area of the 24-ounce Scotts TouchUp bottle, making it the smarter buy when your whole lawn needs attention.

The formula kills over 250 listed weeds including dandelion, clover, and chickweed down to the root, and it’s safe on a long list of grasses: St. Augustinegrass (not Floratam), Bermudagrass, Centipedegrass, Zoysiagrass, Buffalograss, Bahiagrass, Kentucky Bluegrass, Ryegrass, Tall Fescue, and Fine Fescue. Customers note visible effects within an hour, with weeds brown and dead by day 1, though a few found it slower than expected.

Expect mixed results — reviewers are split between “incredibly good” and “not all that.” Your best move is timing: spray small, actively growing weeds when daytime temperatures stay below 90°F. One owner advises covering the whole yard to stop regrowth, not just spot-treating what you see.

A full gallon of ready-to-spray power that clears dandelions in a single pass.

This ready-to-use spray delivers 128 fluid ounces straight from the bottle — no mixing, no measuring — and covers up to 10,000 square feet. Reviewers point out it kills dandelions in one spray, with clover browning in about 3 days, and the formula controls more than 100 tough weeds including alder, aster, nettle, thistle, and yarrow.

The formula relies on dicamba and triclopyr, and it’s designed to kill broadleaf weeds roots and all without harming lawn grasses. It’s clear and nearly odorless, which makes it far more pleasant to use than the gasoline-scented alternatives. Owners note it performs similarly to Weed B Gone but at a friendlier price per 1,000 square feet.

The one real limitation is the sprayer: the built-in hand sprayer is weak for large lawns, and owners recommend transferring this to a pump sprayer for full coverage. One gallon covers about half a yard, so a bigger property will need multiple bottles. Apply when weeds are actively growing and temperatures stay below 90°F, and avoid spraying on windy days.

The patient spot-treatment that kills dandelions at the root — no regrowth next year.

This ready-to-use spray is built for precision, targeting dandelion, clover, and crabgrass without harming your lawn. The catch is the patience it demands: shoppers say the weeds show no change for the entire first week, then in 3-4 weeks the clover and dandelion are all gone. It’s not a quick fix, but it’s a thorough one.

Owners describe dandelions wilting, dying, and then pulling up root easily in about a week, with no regrowth the following year. One long-term user killed Canada thistle permanently using 8-10 bottles over a decade. The built-in surfactant helps the spray stick to the leaves, so it works even on tricky weeds like Creeping Charlie near beds.

The trade-off is coverage and cost — at 24 fluid ounces, this is the smallest bottle here, and it’s pricey for large areas. It’s ideal for spot-treating as needed rather than blanketing a whole yard. Some owners also worry about bee harm and are seeking natural alternatives, so this is one to weigh if pollinators are a priority.

The battery-powered wand that makes spot-treating as easy as pointing and squeezing.

This 1.33-gallon container includes a battery-powered Comfort Wand, which lets you target weeds precisely without pumping or trigger fatigue. The wand delivers a consistent spray with minimal overspray, so you can hit the dandelion without drenching the grass around it. It covers an estimated 10,644 sq ft, making it one of the largest ready-to-use options here.

The formula kills crabgrass, dandelion, clover, chickweed, and creeping charlie down to the root with one application. Buyers report it works slowly but surely — weeds die in about a month without harming grass, and even thistle and tubers get killed. The coverage is generous for spot-treating, with owners noting 1.33 gallons covers 7,000+ sq ft.

The honest caveat is that results vary: some owners mention the spray killed their grass too, likely a factory mixing error, and value-for-money gets negative feedback from a chunk of buyers. It works best on young, actively growing weeds applied in spring or fall when temperatures sit between 45°F and 90°F — though one owner reported success even above 90°F.

One bottle that replaces several — killing crabgrass, nutsedge, and dandelions alike.

This 24-ounce formula is the multi-tasker of the group, tackling crabgrass, yellow and purple nutsedge, dandelion, clover, and 100+ other listed weeds. Buyers who used to juggle multiple herbicides love that this single formulation does it all, and it covers 6,000 square feet, which is impressive for such a compact bottle.

The formula starts working on contact to kill tough weeds to the root, and it won’t harm your lawn when used as directed. Owner reports credit it with killing wild violets — a notoriously stubborn weed — plus dollar weed in Florida and creeping Charlie in Iowa. It’s particularly strong on crabgrass and nutsedge, which many other broadleaf sprays miss entirely.

The downside is that it’s getting hard to find, with some owners reporting it’s no longer available through Amazon and possibly banned in Massachusetts. Overapplication caused lawn yellowing in one case, so the advice is to use lighter, multiple applications rather than drenching. It’s a strong pick if you can find it in stock.

A 5-in-1 spray that kills dandelions while turning your grass a deeper green.

This is the weed-and-feed hybrid, using a high-iron formula with chelated iron (FeHEDTA) to tackle dandelion, oxalis, white clover, chickweed, thistle, and plantain while simultaneously boosting your lawn’s color. It covers up to 1,250 sq ft, and the included hose-end sprayer means no mixing — just attach, turn on the water, and spray.

Customers note weeds turning dark and dying when applied to dry grass, and one owner appreciated that the hose applicator dispensed the product completely with no leftover residue unlike other brands.

The honest limits: owners warn it only covers a small area, and results are mixed — some say it did nothing for common weeds while others saw great results. Support reportedly advised applying under 85°F, which isn’t on the label. If you want the green-up effect and are willing to test it on your specific weeds, it’s worth a shot, but it’s not the most reliable pure weed killer here.

A three-way concentrate that gives hands-on mixers total control over every drop.

This 32-ounce concentrate is a three-way herbicide, combining 2,4-D 30.9%, MCPA 8.23%, and Dicamba 2.77% to target dandelion, chickweed, clover, ground ivy, morning glory, pigweed, plantain, poison ivy, ragweed, spurge, and wild garlic. You measure, mix with water, and spray — the application rate is 0.75 to 1.5 fl oz per gallon per 1,000 sq ft.

Reviewers point out it’s not a Roundup-type instant kill; it takes 3-7 days for weeds to die off, and using a non-ionic surfactant improves absorption. One buyer combined it with Quinclorac to handle tough weeds up to 5 feet tall. It’s safe for grass if not oversprayed, and a reapplication every 4-6 weeks keeps things clean without needing a pre-emergent.

The low-odor formula is ideal for use on all cool-season and selected warm-season grasses, designed to kill weeds, not the lawn. The minimal downsides: it’s a concentrate, so you need your own sprayer, and one owner found it ineffective. Also worth noting: rain within 24 hours slows the effect, so time your application to dry weather.

The prevention-first formula that stops dandelions before they ever sprout.

This is the one spray that works ahead of the problem, using a pre-emergent formula that controls and prevents lawn weeds from growing for up to 4 months. It kills dandelion, poa annua, clover, nutsedge, and other listed weeds in as soon as 7 days after use, and the 32-ounce bottle covers 4,000 sq ft when connected to a garden hose.

The active blend includes Dithiopyr 1.10%, Dicamba 0.44%, and Penoxsulam 0.10%, and it won’t harm most northern and southern turfs when used as directed. It’s ideal for clearing common listed weeds all season long, from simple spot treatments to season-long protection. The ready-to-use spray simply connects to a hose for easy application.

However, this pick comes with the harshest warning in the group. As several buyers put it: “This will kill your grass but does not kill the weeds. A waste of money.” That’s a serious red flag — one owner even sent it back after realizing it hooks to a hose. Some buyers were initially impressed, noting it worked well, but the grass-killing reports make this a gamble. At 2.1 pounds, it’s the heaviest of the 32-ounce bottles here, a subtle sign of its different formulation.
