You put in a lot of time and effort to keep your lawn looking nice. You trim and water it consistently, and then weeds appear and ruin all your hard work. Does this sound familiar? You are not alone. Weeds are the bane of many homeowners and gardeners’ existence. Although there are other options, using a weed killer is one of the most effective ways to get rid of these unwanted plants.
Best Weed Killers for Garden
Herbicides, also known as weed killers, are chemical compounds used to kill unwanted plants in a garden. There are two kinds of weed killers: selective and non-selective herbicides. Selective herbicides are intended to kill specific types of weeds while leaving desirable plants alone, whereas non-selective herbicides will kill any plant that comes into contact with them.
Glyphosate, which is used in many over-the-counter and commercial products, is one of the most common types of weed killers. It is a non-selective herbicide that works by interfering with the production of certain essential amino acids in plants, causing them to die. Another type of weed killer is 2, 4-Dichlorophenoxyacetic acid, which is commonly used to control broadleaf weeds.
Weed killers should be used with caution because they can be harmful to humans and pets if not handled or applied correctly. To avoid skin contact, always follow the instructions on the product label and wear protective clothing and gloves. Keep pets and children away from treated areas until the product has completely dried.
Herbicides can also have an environmental impact, so consider alternative weed control methods, such as hand weeding or mulching, before resorting to chemical solutions. It’s also a good idea to check your garden for new weeds on a regular basis and remove them as soon as possible to prevent them from spreading and necessitating more potent herbicides to control.

Doctor Kirchner Natural Weed Killer
Key Features
- Liquid Formula
- No Mixing Needed
- Kills Poison Ivy and Other Broadleaf Weeds Within Hours
- Contact Type
Overview
The natural weed killer by Doctor Kirchner is pre-mixed and available in a 1-gallon jug. With a natural formula of salt, vinegar, soap, and water, it is a nonselective contact weed killer. It will adhere to foliage, dissolve the waxy leaf cuticle, and penetrate plant tissue with full strength from a trigger-spray bottle or garden pressure sprayer for a more efficient kill than vinegar alone. Both the vinegar and the soap are biodegradable, but regular usage in a constrained space may cause salt to build up in the soil.
With a variety of grassy and broadleaf weeds, as well as a few woody plants like Virginia creeper and poison ivy, we tried Doctor Kirchner Weed Killer in mulched garden beds, tree rings, and along a fence line. We applied the solution with a pump-up garden sprayer with its spray nozzle set to a coarse setting. Within two hours, most of the weeds started to change color, and within 24 hours, they had entirely turned brown. On weeds with harder, thicker leaves, most notably English ivy, the effect was slower and a little less consistent, but even that defoliated in 3 days.
The spray had a strong vinegar odor, which was mildly offensive but might have been overpowering if the nozzle had been set to mist. The yard had a lingering odor for almost a day. Of all the weed killers we tested, Doctor Kirchner Weed Killer provided the finest balance of rapid killing action and little regrowth.
Sunday Weed Warrior Herbicide
Key Features
- Contact Type
- Ready to Use Liquid Formula
- Sprayer Attachment Included
- More Effective on Grassy Weeds
Overview
This pre-mixed gallon-size Sunday Weed Warrior comes with a battery-operated spray pump and wand. Its ammoniated soap mixture sticks nicely to leaf surfaces and starts killing weeds and grass as soon as it comes into touch with them. It is only meant for focused spot treatment because it is a nonselective weed killer; overspray will harm or destroy lawn grass. Shake the jug vigorously before inserting the sprayer adaptor into the cap and beginning to spray.
In addition, to crack weeds on the driveway and sidewalk, we tested Sunday Weed Warrior on crabgrass, clover, plantain, and wild violet in various lawn areas. It performed more quickly than vinegar-based solutions, with visible dieback occurring in about two hours and complete brownout occurring in around eighteen. Compared to vinegar-based treatments, it also penetrated and destroyed Bermuda grass shoots more thoroughly, resulting in nearly complete dieback after just one application. In contrast, vinegar merely killed the leaves on the surface, leaving the blades underneath green.
The battery-operated sprayer was simple to operate and efficiently extracted nearly all of the liquid from the jug. Additionally, it is possible to obtain concentrated refill containers directly from the manufacturer. As long as users take steps to guard against overspray, Sunday Weed Warrior is a great all-around weed killer for lawns.
Bonide Captain Jack’s Deadweed Brew Concentrate
Key Features
- Contact Type
- Liquid, Concentrate Formula
- Plant Derived Active Ingredients
- Noncorrosive to Metal Sprayer Parts
Overview
Broadleaf and grassy weeds are killed by the active component capric acid, a saturated lipid derived from coconut and palm kernel oils, by drying out the foliage. Because of this, Captain Jack’s Deadweed Brew Concentrate works well as a desiccant in gravel regions that are prone to weed growth. The concentrate is packaged with a special measuring cup in a quart-size container. To manufacture up to 8 gallons of spray-on contact weed killer, combine it with water.
On a secondary gravel driveway that was simply two graveled tire tracks with a ridge of green weeds running in the middle, we tested Deadweed Brew Concentrate. We prepared the location by first using a string trimmer to cut down the thick, dense weed cover and remove the trimmings. After waiting three days for some foliage to regenerate, we used a backpack sprayer with a coarse spray pattern to distribute the spray over the entire weed zone.
After the midday spray application, the weed zone turned a light greenish brown in just 4 hours. The weeds were all fully brown the following morning. Even at maximum dosage, this concentrate was odorless, which we loved. Captain Jack’s concentration effectively eliminates weeds across huge areas without unpleasant smells.
Green Gobbler 20% Vinegar Weed & Grass Killer
Key Features
- No Mixing Needed
- Compact and Lightweight
- Handy Trigger-Spray Bottle
- Weed Die Within Hours
Overview
Green Gobbler eliminates the need for mixing and makes grab-and-go weed management simple. With a 20 percent vinegar and water solution, this trigger-spray bottle in the size of a quart is ready to use. Simply use the on/spray switch to select grassy and broadleaf weeds as your target.
At the edges of landscape beds where creeping grasses had started to invade and among vegetable plants in raised garden beds, we tested Green Gobbler vinegar weed killer, which began to act within hours. As opposed to tank sprayers with lengthy spray wands, trigger sprayers required us to hold them within approximately 12 inches of the targeted weeds in order to prevent harm from overspray, which increased stooping and bending. The fine mist covered the weed foliage well, although it produced more spray mist drift than our coarse spray wand did. The scent was so strong that we frequently had to leave the area.
