| Unit Count | 32 Fluid Ounces |
|---|---|
| Item Form | Spray |
| Coverage | 1,120 square feet |
| Item Highlight | Kills Crabgrass, Dandelion, Clover and More as Listed |
Ortho GroundClear Super Concentrate is a tank-sprayer formula for spot and area weed control around landscapes, hard surfaces, and cracks. You mix the concentrate with water, apply with a pump sprayer, and the formula begins to wilt sprayed weeds within hours and is rainfast in about 15 minutes.

Important limitations are that it requires proper dilution and a sprayer, protective gear while mixing and applying, and application conditions (above 60°F and calm weather) for best performance; it is not a selective lawn treatment and will kill desirable turf or plants on contact. Read and follow label safety and re-entry guidance before use.
Best for: Buyers who want an efficient, cost-conscious weed control solution for targeted areas and are comfortable mixing and applying concentrated herbicides with a sprayer.
Less Ideal for: Those who prefer ready-to-use sprays, need a selective lawn-safe product, or are unwilling to follow chemical safety and application instructions.
- Concentrated formula treats up to 1,120 sq. ft. from a single 32 fl. oz. bottle
- Starts working quickly and becomes rainfast about 15 minutes after application
- Effective on a broad range of common lawn and landscape weeds and grasses
- Designed for use with a tank sprayer for flexible spot or area treatment
- Requires dilution and a separate tank sprayer to apply
- Nonselective formula will damage desirable plants or turf on contact
- Safety precautions and protective equipment are necessary during mixing and application
Verdict: A concentrated, fast-acting herbicide for homeowners who want an economical, spray-applied solution to eliminate weeds and grasses in targeted areas.
Roundup Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer with Pump 'N Go 2 Sprayer
| Unit Count | 170 Fluid Ounces |
|---|---|
| Coverage | 400 sq.ft. |
| Item Form | Liquid |
This product combines an all-in-one herbicide and long‑term preventer in a 1.33 gallon ready-to-use formula with an integrated Pump 'N Go 2 sprayer. It is designed for non-lawn areas like driveways, patios, gravel and cracks where you want to both eliminate current weeds and stop new growth for up to a year. The concentrate-free container and extendable wand make spot and area spraying straightforward and reduce bending when treating edges and crevices. It claims visible results within hours and becomes rainproof in about 30 minutes, which helps when weather timing is tight. Practical benefits include broad-spectrum control of common tough weeds and a 400 sq ft coverage per container. Important limitations are that you must spray the entire target area—not just visible weeds—to get the preventer effect, and the product is intended for non-lawn surfaces only, so it is not for treating turf you want to keep. Follow the label for safety and reentry instructions since it is a strong herbicide.
Best for: Buyers who prioritize strong, long-lasting weed control for hardscape and non-lawn areas and want a ready-to-use product with a built-in sprayer for quick, targeted applications.
Less Ideal for: Gardeners who need a lawn-safe solution or who prefer spot-treatment of individual plants without treating whole areas should look for a turf-safe or selective product instead.
- Kills existing broadleaf and grassy weeds and prevents new growth for up to 12 months
- Ready-to-use formula with Pump 'N Go 2 sprayer for accurate, continuous spraying without mixing
- Rainproof in about 30 minutes for faster applications in variable weather
- Extendable wand improves reach and accuracy in cracks, edges, and under decks
- Must spray the entire area to activate the preventer effect, which can use more product

Verdict: Choose this if you want a ready-to-use, long-lasting solution to both kill weeds now and prevent them from returning in non-lawn areas for up to a year.
Ortho GroundClear Year-Long Vegetation Killer2 Concentrate, 32 fl oz
| Liquid Volume | 32 fluid ounces |
|---|---|
| Coverage | 300 square feet |
| Item Form | Liquid |
| Active Ingredients | Imazapyr; Isotropylamine Salt; Pelargonic Acid |
Ortho GroundClear is a fast-acting concentrate designed for homeowners who need long-term suppression of weeds and grasses on hardscape areas. Mix 24 fl. oz. per gallon of water and apply with a tank sprayer to driveways, patios, gravel, fence lines, and other spots where you do not want any plant growth.

A single 32 fl. oz. bottle makes roughly 1.33 gallons of spray and can treat about 300 to 400 square feet depending on label directions. Active ingredients include imazapyr and pelargonic acid, giving both systemic and contact action for thorough kill and up to 12 months of prevention. Important limitations are that it is non-selective so it will kill desirable plants on contact and must be used only where no vegetation is wanted, and it requires careful handling and follow of safety instructions. For budget-focused buyers it delivers long coverage per bottle, reducing how often you need to reapply compared with short-term products.
Best for: Homeowners who need a low-cost, long-lasting herbicide to keep driveways, patios, walkways, and gravel areas free of weeds without frequent reapplication.
Less Ideal for: Gardeners who need to selectively remove weeds from planted beds or who prefer ready-to-use sprays for spot treatments should look for a selective or RTU product instead.
- Year-long prevention of regrowth reduces frequency of reapplication
- Fast-acting and rainproof in about one hour so treatments hold up in changing weather
- Concentrate format treats several hundred square feet from one bottle
- Effective on hardscape and gravel where no plants are desired
- Non-selective formula will damage or kill any desirable plants it contacts
- Requires mixing and a sprayer rather than ready-to-use convenience
Verdict: If you want one concentrated bottle that treats several hundred square feet and keeps hardscape areas weed-free for up to a year, this product delivers strong long-term value.
Spectracide Weed & Grass Foaming Edger Aerosol, 17 oz
| Unit Count | 17 Ounce |
|---|---|
| Item Form | Spray |
| Coverage | 200 linear feet |
| Active Ingredients | Diquat Dibromide, Fluazifop‑p‑butyl, Dicamba |
Spectracide Weed & Grass Foaming Edger is a ready‑to‑use aerosol that delivers a thick foam to target vegetation along driveways, gravel edges, walkways and curbs. You spray to completely cover leaves so the active ingredients are absorbed; treated plants typically yellow and wilt within hours with root kill in one to two weeks. The foam helps minimize drift and makes it easier to treat narrow cracks and gravel margins without soaking surrounding areas. It becomes rainproof in about 15 minutes so light showers shortly after application are unlikely to reduce effectiveness. Practical benefits for driveway use include fast visible control, simple one‑can coverage up to roughly 200 linear feet, and no mixing or specialized equipment. Important limitations: it is nonselective so it will kill desirable plants or turf on contact, safety precautions are required to protect people, pets and nearby plants, and repeated applications may be needed for heavy, established weed growth. Follow label instructions to limit drift into planted beds or water features.
Best for: Homeowners who need a low‑effort, fast way to clear weeds from gravel driveways, edges and hard surfaces and prefer a single‑can application over mixing concentrates.
Less Ideal for: Gardeners who need selective control near ornamentals or people who prefer organic or manual weed removal methods should consider alternatives.
- Foaming spray reduces drift and helps target weeds in cracks and gravel edges.
- Fast acting with visible yellowing within hours and root kill in one to two weeks.
- Rainproof in about 15 minutes so light rain soon after application does not wash it away.
- Ready to use aerosol requires no mixing or extra tools and covers up to 200 linear feet.
- Nonselective formula will damage any desirable plants or lawn it contacts.
- Contains chemical active ingredients requiring protective clothing and careful handling.
Verdict: A simple, fast foaming aerosol that makes short work of weeds in gravel driveways when you want quick, hands‑off spot control.
RM43 Total Vegetation Control 43% Glyphosate Plus Weed Preventer, 2.5-Gallon
| Unit Count | 320 Fluid Ounces |
|---|---|
| Liquid Volume | 320 fluid ounces |
| Coverage | 243 243 square feet |
| Active Ingredients | Glyphosate isopropylamine salt, Imazapyr isopropylamine salt |
RM43 Total Vegetation Control is a concentrated 2.5‑gallon herbicide intended for killing existing growth and preventing regrowth for up to a year on areas where no vegetation is desired. You mix it into spray solution and apply to hardscape edges, gravel driveways, fence rows, and around buildings as either spot treatments or blanket applications on bare ground. The formula pairs glyphosate and imazapyr with a surfactant so it kills grasses, broadleaf weeds, vines, brush and some woody growth and becomes rainfast in about two hours. Practical benefits for driveway use include long residual control that reduces repeat spraying and a large coverage rate that treats many square feet from one container. Important limitations are that it is for non‑crop areas only and will damage desirable plants if sprayed over roots or drift occurs, and the active ingredient blend makes it persistent so care is required where you may later want vegetation to return. Follow label directions for mixing, application timing and safety precautions when using near soil that will be planted later.
Best for: Gardeners, property owners, and maintenance crews who prioritize strong, long‑lasting weed eradication on gravel driveways and other non‑crop hardscape areas and want to minimize repeat applications.
Less Ideal for: Homeowners planning to replant treated areas soon or those needing selective weed control near desirable plants should choose a less persistent or more targeted product.
- Combination of glyphosate and imazapyr for both knockdown and long residual control
- Concentrated 2.5‑gallon container covers large areas without frequent refills
- Rainfast in about two hours so light rain soon after application is less likely to reduce effectiveness
- Suitable for total vegetation control on gravel driveways, fence rows and other non‑crop areas
- Persistent active ingredients that can prevent desirable vegetation from reestablishing for an extended period
- Not safe for use where desirable plant roots may be exposed or where drift could contact nearby plants
Verdict: Choose RM43 when you need a single, heavy‑duty application that delivers broad spectrum kill and up to a year of weed prevention on gravel driveways and other non‑crop surfaces.
Ortho GroundClear Weed & Grass Killer with Comfort Wand, 1 gal.
| Item Form | Spray |
|---|---|
| Coverage | 5120 square feet |
| Unit Count | 128 Fluid Ounces |
| Active Ingredients | Ammonium Nonanoate |
Ortho GroundClear is a one-gallon ready-to-use weed and grass spray designed for spot and surface treatment on driveways, walkways, patios, and landscape beds. The formula absorbs on contact and shows visible browning in about 15 minutes, becoming rainproof roughly two hours after drying, which helps when weather is unpredictable. The included Comfort Wand makes it easy to aim at weeds growing between gravel and pavers without soaking surrounding surfaces. It is OMRI Listed, so it can fit into some organic-minded maintenance routines. Coverage is large for a single container, and the product lists ammonium nonanoate as the active ingredient, which works by contact so small or actively growing weeds are best treated. Because it is a contact herbicide, perennial or well-established weeds may need repeat applications or mechanical removal for full control, and care is required to avoid spray drift onto desirable plants. Follow safety directions and keep pets and children away until treated areas are dry.
Best for: Homeowners who want a practical, hands-on solution to remove weeds from gravel driveways and hardscapes and who prioritize quick, targeted results with minimal setup.
Less Ideal for: People seeking a long-term systemic control for deep-rooted perennial weeds or a total lawn herbicide should consider systemic products or integrated mechanical removal instead.
- Fast visible results on contact, often browning in about 15 minutes.
- Comfort Wand enables precise targeting in gravel joints and along edges.
- Becomes rainproof in approximately 2 hours, reducing loss from unexpected rain.
- OMRI Listed, compatible with some organic production standards.
- Contact-only action means deeper or perennial roots may require multiple applications.
- Spray can damage nearby desired plants if not applied carefully.
Verdict: A fast, ready-to-use contact spray with a comfort wand that makes quick, precise weed control on gravel driveways simple and practical.
Roundup Weed & Grass Killer with Comfort Wand, 1.33 gal.
| Item Form | Liquid |
|---|---|
| Coverage | 400 sq. ft. |
| Liquid Volume | 1.33 gallons |
This Roundup package pairs a 1.33 gallon liquid formulation with a Comfort Wand for easier spraying around beds, walkways, and foundations. It is formulated to kill common broadleaf weeds and grasses down to the root, with visible wilting in hours and rainfast protection in about 30 minutes, so treated areas are less likely to wash away after a brief rain. The wand offers one-touch continuous spray, which reduces hand fatigue during spot treatments and makes edging and targeted applications simpler than using a separate sprayer. Coverage is listed at about 400 sq. ft., appropriate for small yards, beds, or multiple spot-treatment sessions. Important limitations are that this is a nonselective herbicide so it will damage desirable plants if contacted and the product directions include replanting wait times of 1 to 30 days depending on use. Users should follow label precautions about keeping people and pets away until spray has dried and applying only in calm conditions to avoid drift.
Best for: Buyers who want a straightforward, ready-to-use herbicide for targeted spot treatments and edging where quick, reliable weed control is the priority and minimizing application fuss matters.
Less Ideal for: Large properties or users who need selective lawn-safe control should consider professional application methods or products formulated specifically for turf.

Choosing the Right Weed Killer for Sidewalks: Key Factors to Consider
Mode of Action and Kill Speed
How a product kills weeds matters for sidewalk use. Fast-acting contact herbicides burn back foliage quickly, which is useful when you want a visible result within days. Systemic herbicides move into roots and translocate, which can prevent regrowth from tough perennials but usually take longer to show effects.
Consider the types of weeds you face. Annual grassy weeds and young broadleaves often respond rapidly to contact products, while perennial weeds with deep roots may require systemic activity or repeat applications. For sidewalks, a mix of quick knockdown and follow-up treatments is often the most practical approach.
Surface Compatibility and Stain Risk
Some formulations can discolor or etch concrete, pavers, or certain sealers. Products with surfactants or dyes may leave residues visible on light-colored masonry. Choose options labeled safe for impervious surfaces and follow dilution and rinse instructions.
Also think about how runoff will behave. A heavy rain shortly after treatment can carry chemicals into cracks, gutters, or planting beds. Proper application timing and limited volumes reduce staining and runoff risk.
Application Method and Precision
How you apply the product affects both effectiveness and safety. Spot-spray bottles and foam applicators let you target individual cracks without overspray. Hose-end sprayers cover large sidewalks quickly but can increase drift and accidental exposure to adjacent plants.
For tight joints or small patches, a bottle with a narrow spray or a brush-on gel reduces waste and keeps herbicide where you want it. Consider ergonomics as well: if you have long stretches of sidewalk, a back sprayer or larger container may be more efficient than repeated small bottles.
Persistence and Follow-up Needs
Residual control-how long the product prevents new weeds from emerging-can cut down on repeat treatments but may increase non-target exposure. Short-residual contact products let you spot-treat as needed without lingering chemistry, while products with longer soil activity reduce frequency but require more caution around desirable plants.
In high-traffic or frequently rinsed areas, residual activity may be less reliable, so plan for scheduled follow-ups. For sidewalks with recurring seed sources, combine mechanical removal with a product that offers some persistence to reduce seedling establishment.
Safety for Nearby Plants and Pets
Sidewalk edges often border lawns, flower beds, or container plantings. Choose products and application techniques that minimize drift and root-zone exposure to desirable vegetation. Some herbicides have volatile components or require surfactants that raise translocation risk to nearby plants.
Think about pet and child access. Many formulations dry quickly, but treated surfaces can still transfer residues on paws or shoes for a short time. Read label reentry intervals and select products with clear guidance for domestic settings.
Label Clarity and Legal Compliance
Labels provide the legally enforceable instructions for safe and effective use. For sidewalk work, clear directions on dilution, reentry time, disposal, and allowed application sites are essential. Products that list sidewalk, pavement, or masonry on the label reduce uncertainty.
Check for local restrictions on certain active ingredients. Some municipalities regulate specific herbicides or require restrictions near waterways. Choosing openly labeled products with straightforward disposal instructions helps you stay compliant and reduces environmental risk.
When to Use Contact Versus Systemic Treatments
Contact herbicides scorch exposed foliage fast and are ideal for visible cleanup of young seedlings and annual weeds that grow in sidewalk cracks. They give quick visual control but usually do not stop regrowth from established roots.
Systemic options move into the root and can suppress perennial species more effectively, though they often require longer intervals to show results. In many sidewalk situations, an initial contact treatment followed by a targeted systemic on persistent patches balances speed and durability.
- Contact: quick knockdown, best for annuals and fresh growth
- Systemic: slower but better for deep-rooted perennials
- Combine methods when site has a mix of weed types
Best Application Techniques for Narrow Joints
Small cracks and narrow joints require precision. Use a narrow-stream nozzle, foam applicator, or a brush-on formulation to place herbicide directly on foliage and avoid runoff onto paving surfaces or nearby plants. Apply on dry foliage and in calm weather to minimize drift.
For sidewalks with lots of foot traffic, treat early in the day and allow the product to dry fully before people or pets use the area again. Mechanical scraping or a wire brush before treatment exposes crowns and improves contact with the chemical.
- Brush-on gels reduce overspray
- Spot-spray nozzles increase precision
- Pre-treatment scraping improves contact
Managing Regrowth Without Overusing Chemicals
Mechanical removal combined with targeted herbicide use reduces the total chemical load. Pull or scrape large clumps, then apply a focused treatment to remaining roots or regrowing shoots. Frequent sweeping and seed-source control along edges cut down on recurring weeds.
If you plan seasonal treatments, time them for periods of active weed growth so systemic materials translocate better. Avoid repeated blanket treatments across the entire sidewalk if only isolated patches need attention.
- Combine physical removal with spot treatments
- Address seed sources along edges and gaps
- Time systemic applications during active growth
Protecting Adjacent Plants and Lawns
Create physical barriers, such as cardboard or plastic edging, when treating near flower beds to prevent accidental drift or runoff. Rinse equipment away from garden beds and avoid applying during windy or rainy forecasts that could move product into planting areas.
If roots of desirable plants extend under sidewalks, avoid systemic herbicides that translocate through root systems unless you can isolate the treatment area. Use lower-risk, contact-focused methods when roots are a concern.
- Use physical barriers when spraying close to beds
- Avoid systemic options where roots cross under hardscape
- Monitor treated margins for signs of non-target stress
Timing Treatments for Weather and Foot Traffic
Select a calm, dry day to ensure material stays on foliage and does not wash off. Early morning often offers low wind and moderate temperatures that favor uptake. Avoid applying before heavy rain or when temperatures exceed label recommendations.
Consider pedestrian schedules. Apply when the area will be least used for several hours and post simple warnings if needed until the product dries. This reduces transfer risk and improves overall effectiveness.
- Choose calm, dry weather windows
- Avoid application before expected heavy rain
- Treat when foot traffic will be minimal
How We Chose the Best Weed Killer for Sidewalks
We focused on products and formulations suited to hard surfaces, small cracks, and areas where nearby ornamentals or turf require protection. Selection criteria emphasized speed of visible control, persistence to reduce repeat treatments, application method for tight joints, and safety for concrete, pavers, and nearby plantings. We also considered ease of use for homeowners: whether a ready-to-use sprayer, hose-end, or concentrate is more practical for the average sidewalk, and how clear the label directions are for spot applications. Excluded items included garden-targeted herbicides designed for turf or broad landscape beds where root uptake and systemic action are needed, since those can increase non-target risk on hardscape edges. Also left out experimental or unproven mixes and professional-only industrial products that require special licensing. The resulting shortlist favors formulations and delivery methods that balance effectiveness on common sidewalk weeds with predictable behavior on hard surfaces and straightforward safety instructions.
FAQ
Can I use garden herbicides on sidewalks without harming nearby plants?
It depends. Some products are labeled for hardscape use and have low risk when applied carefully. Precision application and physical barriers reduce drift. Avoid systemic formulas near plants with roots under the pavement to prevent uptake.
How soon after treatment can people and pets use the sidewalk?
Reentry time varies by product. Many contact formulations dry within an hour and pose minimal transfer risk once dry, but always follow the label reentry instructions. Keep pets off the area until the product has dried and any specified interval has passed.
Will a single treatment prevent weeds from coming back in cracks?
Often not. Annual weeds may be controlled with one application, but perennial species and persistent seed banks usually require follow-up treatments or mechanical removal. Residual products can reduce frequency but do not eliminate future maintenance.
Are there non-chemical ways to keep sidewalks weed-free?
Yes. Regular scraping, hand-pulling, wire brushing, and applying polymeric sand or sealants in joints reduce weed establishment. Non-chemical methods are labor-intensive but lower environmental risk and complement targeted herbicide use.
Can runoff from treated sidewalks harm waterways or drains?
Runoff can carry herbicides into drains and water bodies, especially if heavy rain occurs soon after application. Use minimal volumes, avoid treating before rain, and follow label guidance on allowed application sites to reduce runoff risk.
Final Verdict
For sidewalks, prioritize precision and surface-safe formulations that match the weed types you face. Quick-contact products are helpful for visible cleanup and routine maintenance, while systemic options are better for stubborn perennials when applied carefully. Balance speed, residual control, and non-target safety when deciding. Use targeted application methods, follow label directions closely, and combine mechanical measures with selective herbicide use to keep sidewalks clear while protecting adjacent plants and surfaces.
