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.

Spectracide Weed & Grass Killer Concentrate, 16 fl oz
| Unit Count | 16 Fluid Ounces |
|---|---|
| Item Form | Spray |
| Coverage | 7 fl oz per gallon covers up to 300 sq ft |
| Rainproof time | 15 minutes |
| Visible results | As fast as 3 hours |
This Spectracide concentrate is a practical, fast-acting option for clearing unwanted weeds and grasses from hard surfaces and around garden beds. You mix the 16 fl oz bottle with water and apply with a tank sprayer for spot treatments; the label rate (7 fl oz per gallon) covers roughly 300 sq ft per treatment. The formula is rainproof after 15 minutes and can show visible dieback in as little as three hours, letting you replant in treated areas after about a day. It is nonselective, so it kills foliage down to the root and requires care to avoid desirable plants. Because it is a concentrate, small bottles treat a larger area than ready-to-use sprays, which is useful for recurring patch treatments while keeping storage space low. Important limits are the usual safety precautions for herbicides and the need to shield nearby plants and follow temperature guidance for best results. For someone wanting a straightforward, effective knockdown of pavement and edge weeds, this performs reliably when used as directed.
Best for: Buyers who want a cost-effective, no-nonsense herbicide to tackle spot infestations on driveways, walkways and edges and who are comfortable mixing and applying a concentrate.
Less Ideal for: Customers who need a gentle or selective lawn-safe product or who prefer ready-to-use sprays with no mixing should look elsewhere.
- Concentrated formula covers a larger area per ounce than ready-to-use products
- Fast visible results in as little as 3 hours and rainproof after 15 minutes
- Kills weeds and grasses down to the root for longer-lasting control

| 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.

Choosing the Right Weed Killer for Between Pavers: Key Factors to Consider
Active Ingredient and Mode of Action
Knowing what active ingredient is in a weed killer determines which weeds it controls and how fast it works. Contact actives kill the visible foliage quickly but often leave roots intact, which can be fine for annual weeds; systemic actives travel into roots and are usually better for perennial or deeply rooted weeds common between pavers.
Mode of action also affects resistance risk and whether repeat applications will be effective. For paver joints you want an ingredient with label guidance for spot treatment and root uptake without requiring large broadcast applications.
Residual Control and Longevity
Residual control refers to how long a product prevents new weeds from emerging after application. In tight, sandy, or compacted joints, short residual effects mean you will see rapid regrowth, while longer residual formulas reduce repeat work.
Consider the desired maintenance rhythm: short-season solutions suit gardeners who plan frequent manual maintenance, while longer residuals are better if you want to minimize repeat treatments. Also note that residual performance can drop with heavy rain or frequent foot traffic.
Application Method and Precision
Effective treatment between pavers requires precise delivery. Ready-to-use sprayers with narrow tips, wand sprayers, gel formulations, or brush-on applicators help target joints while minimizing contact with adjacent plants or turf.
Think about access and ergonomics. Small hand applicators work well for tight areas, while hose-end sprayers or concentrated mixes can be efficient for larger paved surfaces but require more skill to avoid overspray.
Safety and Impact on Surrounding Plants
Weed killers used between pavers sit very close to garden beds and lawn edges. Drift, runoff, and accidental contact can injure desirable plants, so label directions about buffer zones and plant sensitivity are critical.
Choose formulations and applicators that limit drift, and factor in wind, temperature, and the presence of pollinator-attractive blooms. If you have nearby vegetables, shrubs, or newly installed plants, opt for low-drift methods and follow reentry and watering restrictions on the label.
Weather Tolerance and Rainfastness
Rain soon after application can wash away some products before they bind to soil or are absorbed by plant tissue, reducing effectiveness. Look for rainfast intervals on labels and plan applications during a forecast window with little chance of rain.
Heat and strong sunlight also influence performance. Some actives break down faster under UV exposure. For paver settings that are in full sun most of the day, choose options with proven stability in hot conditions or schedule applications during cooler parts of the day.
Surface Compatibility and Residue
Some formulations can stain porous paver materials or leave residues that are hard to clean. Consider the paver material-concrete, natural stone, or brick-and whether the product has notes about staining potential or cleanup requirements.
If you care about appearance, test any product in an inconspicuous spot before broad use and follow label guidance for rinsing or neutralizing spills on hard surfaces.
Preparing Joints Before Treatment
Effective control starts with physical prep. Remove large weeds and pull loose debris from joints so the product contacts living tissue and root zones rather than dead material. Use a stiff brush, pointing tool, or narrow nozzle vacuum to clear out accumulated soil and seeds.
Damp joints can help systemic actives move into roots, but saturated conditions reduce uptake and may cause runoff. If soil is very dry, water lightly a day before treatment to improve absorption, then wait until the surface is no longer wet before applying the herbicide.
- Clear loose moss, soil, and plant debris from joints first
- Pull or cut large weeds so remaining regrowth is exposed
- Lightly water dry joints 24 hours before applying systemic products
Application Tips for Tight Spaces
Use small, precise applicators for narrow joints to avoid contact with surrounding plants. A foam brush, syringe-style applicator, or a sprayer with a narrow stream helps place product only where needed. For granular options, apply thinly and sweep any spilled granules back into the joint.
Work in short passes and avoid walking over treated areas until the product is dry. Wear gloves and eye protection, and keep a damp cloth handy to wipe accidental splashes off pavers or plant foliage.
- Choose a brush-on or narrow-tip applicator for precision
- Apply in calm conditions to reduce drift
- Keep reentry time and drying instructions in mind
Managing Regrowth Without Chemicals
Nonchemical strategies reduce dependence on herbicides and are useful between pavers. Regular brushing, scraping, and a quick pass with a heat weeder can damage young shoots before they root deeply. Manual removal is effective for small areas and avoids risk to nearby plants.
For long-term suppression consider improving joint material. Re-sanding joints with polymeric sand or using a fine mortar can reduce seed lodging and make it harder for weeds to establish. These measures work synergistically with occasional targeted treatments.
- Brush or scrape joints regularly to remove seedlings
- Use polymeric sand or joint mortars to limit seed lodgment
- Heat tools can be effective for spot treatment on hard surfaces
Timing Treatments for Best Results
Treat during active weed growth for best uptake. Spring and early summer are often ideal because plants are putting energy into leaves and roots. Perennial weeds may need treatment later in the season when they move carbohydrates to roots.
Avoid treating during extreme heat or drought when plants are stressed and less likely to absorb systemic actives. Check the weather for minimal wind and at least several hours without rain after application.
- Apply while weeds are actively growing for systemic uptake
- Delay treatment if heavy rain is forecast within the label rainfast window
- Consider follow-up spot treatments for stubborn perennials
Safety and Clean-Up After Application
After treating paver joints, clean applicators and any spills promptly according to label instructions. Rinse equipment away from garden beds and avoid pouring rinse water into soil near sensitive plants. Store chemicals in original containers and out of reach of children and pets.
Monitor treated areas and note how quickly weeds brown and decline. If desirable plants show signs of drift damage, flush the foliage with water and review label guidance for mitigation steps.
- Clean tools and applicators after each use
- Rinse spills from pavers immediately when safe to do so
- Keep records of applications and observed effects
How We Chose the Best Weed Killer for Between Pavers
We selected products based on criteria that matter for killing weeds in narrow paver joints and preventing quick regrowth. Our evaluation prioritized speed of action against common joint weeds, residual control in compacted substrate, application precision for narrow joints, and safety when used near ornamental plants or grass. We also weighed how easy each product is to apply in confined spaces, including available applicator types and compatibility with spot treatments. Durability of ingredients under sun and rain mattered because surface runoff and exposure change effectiveness. Finally, we considered formulation types and preparation needs to match common gardener skill levels. We excluded broad lawn or agricultural herbicides that are not formulated for spot treatment or that require professional licensing. We also filtered out products that lack clear label directions for use in hardscape joints or that present high risk to nearby desirable vegetation. The result is a shortlist of options that balance quick knockdown, meaningful residual control, precise application, and practical safety considerations for use between pavers.
FAQ
Can I use any weed killer on the joints between pavers?
Not all weed killers are suitable. Look for products labeled for spot treatment on hardscapes or for use in cracks and joints. Avoid broadcast lawn herbicides that do not provide guidance for application near desirable plants or hard surfaces.
How long after treatment will weeds die?
Timing varies by active ingredient. Contact products can brown foliage within hours to days but may not kill roots, while systemic products often take several days to a few weeks to fully kill perennial roots. Expect visual effects sooner with contact actives.
Will rain wash the product out of the joints?
Rain can reduce effectiveness if it occurs before the product becomes rainfast. Check the label for the specified rainfast interval and avoid applying if rain is likely during that period. Proper timing and application method reduce wash-off risk.
Is it safe to use weed killers near flowers and vegetable beds?
It often depends on the formulation and application precision. Use low-drift applicators, maintain buffer distances listed on the label, and avoid spraying when wind could carry droplets. When in doubt, remove or cover nearby plants during treatment.
How often will I need to reapply to keep joints clear?
Reapplication frequency depends on the product's residual control and local weed pressure. Some products require seasonal spot treatments, while others may allow longer intervals. Combining chemical control with mechanical cleaning extends the time between treatments.
Are there nonchemical options that work between pavers?
Yes. Regular scraping, brushing, applying heat, and refilling joints with polymeric sand or mortar are effective nonchemical strategies. They are labor intensive but reduce chemical use and can be combined with occasional targeted herbicide treatments.
Final Verdict
For weeds growing between pavers, prioritize a product and application method that matches the weed type and your maintenance goals. Use systemic actives for persistent, root-forming perennials and contact treatments or mechanical methods for annual weeds and quick cleanup. Precision applicators, proper timing, and joint preparation reduce the need for repeated treatments and minimize risk to nearby plantings. Balance speed of control with safety and residue concerns. With careful selection and targeted application you can keep pavers weed-free while protecting surrounding plants and preserving the look of your hardscape.
