Herbicides are used to kill unwanted vegetation on your property. Many herbicides are selective and will only kill weeds. Unfortunately, there are times when a homeowner has grass and weeds growing in a spot that they shouldn't. For example, a homeowner may not want grass and weeds to come within 6 to 12 inches of an outdoor pool or sandbox. In these cases homeowners can turn to Roundup Weed and Grass Killer, which will kill all vegetation.
Don appropriate safety gear, including long clothing and safety goggles.
Spoon 5 tbsp. of Roundup Weed and Grass Killer in your garden sprayer for every 300 square feet of property you need to cover.
Add 1 gallon of water to your garden sprayer for every 300 square feet of property you need to cover.
Mix the two ingredients together. You can do this with an unused paint mixing stick, or by placing the cap on the garden sprayer and shaking it vigorously.
Pump the pump handle until enough pressure has built up that you can't press the handle down any more. Spray the unwanted grass and weeds until they are thoroughly wet.
