Roundup is a herbicide used to kill weeds. It comes in a variety of compositions including Roundup Weed and Grass Killer Ready-to-Use Plus and Roundup Weed & Grass Killer Super Concentrate. Once applied, it is best to wait until the Roundup has dried before allowing pets and people to enter the area.
Put on safety gear
Before using Roundup, it's important to don gloves, long pants, goggles and a mask. Roundup contains chemicals such as glyphosate and isopropylamine salt, which can be extremely harmful if they are breathed in, contact the skin or are ingested.
Protect surrounding plants
Roundup kills any plants that it comes in contact with. Therefore, it's important to shield surrounding plants while using Roundup. Use plastic sheets, tarps or cardboard barriers to cover and protect neighboring plants.
Dilute and spray
The concentrated Roundup product needs to be diluted with water before use. Simply follow the manufacturers diluting directions on the bottle. Once the Roundup is ready for use, rotate the nozzle to the course spray setting and saturate the weeds. It's important to wet the entirety of weed, including the flowers, leaves and stalk, for the best results. It usually takes about 6 hours for the effects of Roundup to be seen.
