## Description

Take on all the weeds and grasses you don't want around your home with Ortho® GroundClear® Year Long Vegetation Killer1. This weed killer concentrate formula kills weeds, grasses and unwanted vegetation, and prevents new growth for up to 1 year. This fast-acting weed and grass killer starts working immediately. Use on areas where weeds, grasses and plants are not desired, including driveways, sidewalks, gravel areas, rock and desert landscapes, under decks, on parking areas, along fences and curbs, and in unplanted areas. This product is a concentrate and must be diluted with water before applying. To apply, mix 24 fl. oz. with 1 gallon of water in a tank sprayer to treat up to 300 sq. ft. For best results, apply to actively growing weeds on a sunny day when temperatures are above 60°F. Apply only to areas where vegetation is unwanted for 1 year. Keep people and pets off treated areas until spray has dried. Each 2 gal. bottle of Ortho® GroundClear® Year Long Vegetation Killer1 makes approximately 10.67 gallons prepared solution.

Review: First gallon worked great. Second gallon not so much. Didn't kill as long, maybe only half the time. Doesn't kill elephant ears. First impression was great. Now looking for alternatives.
Review: When I first became a home owner, I purchased Ortho GroundClear to kill everything between the rocks in a long path from my house to our firepit. I was amazed and ecstatic with the results. I strayed from Ortho and found a cheaper vegetation killer. The new product worked but did not last all season....so I ended up using more product and wasting more time by reapplying. Ortho GroundClear kills all vegetation quick and keeps it under control for the season. I noticed that season after season the vegetation elimination process gets easier. I feels it keeps some weeds from returning. I am a fan of this product. If I am near grass that I don't want damaged, I use a sprayer (no wind day) to apply a light coating to dampen the soil with an extra spray on existing weeds. On the end of our stone driveway where weeds and grass sprout up, I use a watering can for a one and done for the season application. (Tip: Mark that watering can with an "X" so you don't use it for anything else.) (Another Tip: I have a bucket that I keep all the items I use to mix, measure and stir this product with. When I am ready to start the vegetation elimination process I have everything I need in one place and don't risk using these items for another product and cross contaminate.)

### ⭐⭐ Review
*by A***R on 4 April 2025*

We'll see. For some reason, this application I did not see any results, - applied full sun, no rain and full strength. It's taken about 7 days to see activity of having started to "kills" weeds, plants, etc. "ground clear". I started to wonder and was preparing to apply again presently. But today, about a week later I am starting to see "browning". When applied, as happens, one can see the "white" ish coloration from the spray, especially if used in a stone, concrete walk way, etc. I saw a nice coating. One should not have to "soak" a plant - but, I make sure as well as I can and with a pro sprayer I've been using for years, and well maintained. I also have the weed killer for lawns - and was wondering if might have to use that - since sometimes the combination seems "more" affective. Now, I'll wait, and if have left over from lawn spots. So, I don't get why I might experience different results when from one year to the next usually see "browning" no more than 3 days later, but this time I did. This stuff is, for me, costly and "work" to walk my property and spray it - so, I expect good results for my time, money and efforts - I'm not "playing" at this, not a hobby, etc. So, I hope that helps someone. So, use the max dilution per the label, coat it all well and it may take 7 days. As far as preventive for the season - eh, well, we'll see. I tend to use "preen" as well. I can't imagine germination prevention for 2 months without a time release dropped chemical, unfortunately.
