“This product arrived on time and was well-packaged. I mainly used it to eliminate unwanted grass in my flower garden. It seems like it could also tackle weeds effectively, but for now, it’s perfect for my needs!”

"I find that Ortho GroundClear Weed and Grass Killer works amazingly well! It eliminates dandelions, chickweed, and other stubborn weeds with ease. The Comfort Wand makes application simple and precise, helping me save money on yard work."

"I have to say, this is an excellent organic herbicide when used as directed. It effectively kills the weeds and grass I sprayed, with noticeable results in just a few hours. I use it around my yard and for controlling stubborn Bermuda grass, but I make sure to spray before the weeds get too large."

"Living in the desert, I've tried numerous weed killers, and this one works the best. Since using it a couple of months ago, nothing has grown in my backyard, which has really surprised me. I highly recommend it!"

"I was pleasantly surprised by the results. I sprayed over the weeds, and within a day, they dried out and died. It’s been weeks, and not a single weed has returned!"

"I’ve tried many weed killers before, but this one was a game-changer. Great results in 24 hours and stellar by day 3. I even bought some for my elderly parents!"

"Spectracide Weed & Grass Killer has completely transformed my battle against unwanted vegetation! From the moment I applied it, I saw remarkable efficiency in eliminating weeds. Within days, my yard was clear of weeds, and the lasting effects have saved me time on maintenance. I couldn't be happier with my experience!"

"I recently tried the Spectracide Weed & Grass Killer (Refill) for my garden. It did a decent job controlling most weeds and was easy to use. However, I found it wasn't as potent as the concentrate version I previously used, taking longer for noticeable results. Still, it's a reliable option for smaller areas."

"I'm really excited about how well this product works. The sprayer is fantastic—no pumping needed! It killed my weeds within just a couple of days. I used Spectracide Weed and Grass Killer instead of an expensive brand my neighbor recommended, and I’m so glad I did!"

"I've been using this product for a few years, and it’s simply wonderful at eliminating those pesky weeds quickly. However, I’ve had to use an old spray bottle instead of the sprayer that didn’t work for me."

"I’ve had this since June 2021, and the battery-powered sprayer has held up well. It’s not an overnight solution, but it gets the job done in a few days. I found that holding the container higher helps the sprayer work better."

"I chose this product for its natural ingredients and effectiveness against poison ivy. After spraying, most weeds were dead within a few hours. However, I did experience a strong vinegar smell that caused some skin irritation, so I recommend wearing protective gear. Despite this, I’m impressed with its performance and appreciate supporting a small business."

"Using this weed killer was a game-changer for my large yard. I loved that it was pet-safe and worked quickly, with most weeds disappearing within a day. The only downside was the strong odor, which lingered for a day or two. I switched to a better sprayer for easier application, and I’m happy to invest in a product that’s safe for my pets."

"I was initially skeptical but decided to try this natural herbicide for the foxtails in my yard. Within just four hours, they were all brown and dead! The strong vinegar scent is definitely noticeable, and it can cause skin burns, but that’s expected with vinegar. I’m thrilled to have found a product that’s both effective and safe for my dogs."

“I have about 1 acre of zero scape, and I needed a product that could be an all-in-one solution for spring use. I used to mix glyphosate with a pre-emergent chemical, but after using this product, my issues were resolved. It’s the best balance for a once-a-year application to provide year-round control.”

“People around me don’t understand why I pay $80+ a gallon for weed killer when cheaper options are available. But this product works the first time, attacking the roots of weeds and eliminating them completely. It also has pre-emergent properties that prevent new growth for up to a year. Just be cautious where you spray, as it can affect grass growth for a while.”

“My fiancée is a big fan of this product! We use it in areas where we don't want any weeds, and it works great!”

"I've been using the Ortho WeedClear Weed Killer for a while now, and I'm really impressed with its effectiveness. The Ready-To-Spray feature makes it super convenient; I just attach it to my hose and cover up to 16,000 square feet. It targets common weeds like dandelions and crabgrass while keeping my grass safe. I appreciate that it's rainproof soon after application and the results last a long time. I highly recommend it!"

"I had high hopes when I first bought this product, but I encountered issues with the sprayer not working. I tried it a second and third time, but it still only watered my weeds. I regret purchasing it; if the sprayer doesn't work, the product is useless. I wish I had a better experience.”

"I had a serious problem with Canada Thistles taking over my yard. After endless pulling, I decided to use this non-toxic solution. On a hot day, I applied it and within two days, the weeds turned brown and disappeared! Now, my flower bed looks so much better. It's easy to manage the few remaining weeds, and it even helped with crabgrass!"

"This product is great for controlling weeds! It looks and smells like vinegar, and it's incredibly effective. Most weeds die within a day. However, I encountered one type that wasn’t completely killed but was weakened, which helped me tackle it better. I love using this because it's safe for the environment, especially since we live near a stream!"

"I appreciate this vinegar-based product for its effectiveness in weed control. Unfortunately, the sprayer that came with it isn't very reliable, so I had to switch to my old one. Nevertheless, the product itself works really well on almost all common weeds."
