Scotts Miracle-Gro Company makes several products to get rid of grass and weeds. One of those products is called Roundup Weed and Grass Killer. This product will allow you to treat areas of your lawn where you do not want grass to grow. This could include the area around your mailbox, or in the cracks of your sidewalk. It is important that you follow all directions on the Roundup product label to ensure you use the product safely, and that it is effective at killing the grass.
Put on a long shirt, and a pair of long pants. Do this even if it is hot out, as Roundup can cause skin irritation. It is also a good idea to wear boots.
Slide a pair of gloves on your hands and then place a mask over your face. Finish off your safety preparations by wearing a pair of goggles. Roundup can be breathed into the lungs, or splashed up into the eyes. It is better to be safe than sorry.
Place 3 tbsp. of Roundup Weed and Grass Killer into a backpack sprayer.
Add 1 gallon of water to the backpack sprayer and then mix the two liquids together. This is enough weed and grass killer to cover 300 square feet. If you need more than that, double or triple the ingredients.
Spray across the areas of your property where you want to kill the grass. Make sure the grass is completely wet, and that you are applying it on a day that exceeds 60 degrees F in temperature.
