Description

Ortho® GroundClear® Weed & Grass Killer Super Concentrate1 kills the toughest weeds and grasses to the root. This weed control product starts working immediately to kill all types of weeds and grasses including clover, dandelion, oxalis, chickweed and crabgrass. In addition, it is rainfast 15 minutes after application. Use this weed control product around trees, shrubs and fences, and on patios, paths, sidewalks, sidewalk cracks, walkways, and driveways. To use, dilute this weed killer concentrate per label directions and apply with a tank sprayer. Spray weeds to thoroughly wet foliage, but not to the point of runoff. For best results, apply when weeds are actively growing and the air temperature is above 60°F. Sprayed weeds begin to wilt hours after application, with complete kill within days to 1 to 2 weeks. People and pets may re-enter after the treated area has been allowed to dry. This 32 fl. oz. container of Ortho® GroundClear® Weed & Grass Killer Super Concentrate1 treats up to 1120 sq. ft. Trust Ortho® to keep your landscape free of weeds and unwanted grasses.

How to Use

  • When you are ready to treat weeds, first gently shake the container of Ortho® GroundClear® Weed & Grass Killer Super Concentrate1 to mix it.
  • Next, pour the desired amount into a plastic, aluminum, or stainless steel tank sprayer. (Do not use a backpack sprayer.)
  • - For established and difficult to control weeds add 10 fl. oz. to 1 gal. of water.
  • - For weed control, add 5 fl. oz. to 1 gal. of water.
  • (Each gallon mixture makes enough treatment to cover up to 350 sq. ft.)
  • Apply in a uniform pattern.
  • Make sure to spray only the weeds you want to kill by thoroughly wetting the foliage but DO NOT spray in a way that will create runoff.
  • After applying, clean the sprayer by rinsing it three times on bare soil or gravel.

Where Not to Use

  • DO NOT spray this weed killer on or around food or feed crops. You should also not spray any plants you want to keep.

Where to Use

  • Ortho® GroundClear® Weed & Grass Killer Super Concentrate1 can be used to spot-treat weeds around perennial landscape plants, shrubs or trees. It can also be used across patios, walkways, driveways, gravel or mulch beds, and along fences or around buildings.
  • It can also be used in broadcast applications when performing lawn renovations or preparing landscaped areas.

When to Apply

  • To achieve the best results, apply when weeds are actively growing, the air is calm, and the temperature is above 60°F. Applying in calm weather when rain is not predicted for 24 hours will also help to ensure that wind or rain does not blow or wash pesticide off the treatment area.

How Often to Apply

  • Do not make more than two broadcast applications per year.

Watering Tips

  • If soil in the area that is to be treated is dry, water every other day for a week before applying this weed killer.

Rated 5 out of 5 by from Easy and fast weed elimination! Excellent product. Been using it for years and it eliminates the weeds by the next day, or even sooner. Makes weed killing easy on my acre.

Rated 5 out of 5 by from Gets It Done Big Time A very hi performance product, where more is better when mixing just wastes this pricy product. Be VERY careful where you use this product, strongly suggest not to use as an lawn edging supplement because it will migrate deep into the soil and spread after watering/rainy days and will definitely harm existing grass or foliage several months down the line. Lastly, give it time to work and it will. Yes it’s expensive yet well worth every penny in the long run

Rated 5 out of 5 by from Ortho Concentrate #1 Fantastic product to killer those nasty driveway weeds, have a very long driveway and 1 application starts killing within the 15 minutes as stated on bottle. I do use the concentrate for my stubborn weed trees and Johnson grass( note cut to base then spray-gets to the roots fast on a hot day). I have tried others but Ortho has my back and kills them weeds. Now I may need a 2nd application for emerging baby weeds after a rain storm. Weeds seem not to come back and my driveway stays weed free all summer and fall.

Rated 5 out of 5 by from Great Product! Great product. Easy to mix, easy to use. No guesswork! Bee using it annually for almost 20 years. Lives up to the hype!

Rated 5 out of 5 by from Impressive We have had a huge amount of weeds this year in the desert southwest, very tough to control and apparently impervious to the normal weed killers previously used. I tried this concentrate after seeing results at a neighbor's yard, and I was very happy with the results. Weeds treated with a double dose of the previous weed killer are still not dead. Weeds treated with this product, in their majority, were dead at the end of the day of application. Impressive
