Commercial Weed Killer FAQ
How to use commercial weed killer
Commercial weed killers should always be used with care, as glyphosate is an extremely strong chemical. You should wear protective gear when applying the weed killer, and keep pets and children inside.
To use concentrated glyphosate, you should measure the amount of glyphosate recommended by the manufacturer into your sprayer tank. Pump your tank sprayer until it’s ready to use, then adjust the spray nozzle to a course spray as opposed to a mist. Spray the weed killer directly onto the plant or weed you wish to kill, as well as between slabs of concrete and the edges of your patio. The weeds you spray should be thoroughly wet.
Wash your sprayer tank thoroughly, being careful not to get any product on your skin. Any weeds that don’t die within a few weeks should be treated again. Do not touch any of the wet plants.
How long does it take for commercial weed killer to work?
Commercial weed killer is made for rapid results, but its effectiveness does depend on the season. If you are spraying the weeds on a hot day, you should see visible results in just a few days. More stubborn weeds will take longer.
If you are spraying the weed killer on a cold day, results will take longer still. If it rains straight after you have sprayed the garden, you may need to reapply.
Is commercial weed killer safe for plants?
In short, no! Commercial weed killer will kill most plants it comes into contact with, which is why it’s important that you only spray a direct stream onto the weeds you wish to kill. Don’t touch any plants sprayed with glyphosate as you may accidentally spread it to another plant.
Is commercial killer safe for pets?
Commercial weed killers contain glyphosate which isn’t safe for pets. Ensure you have a backup area where they can play safely while the chemical dries on the plants. When pets come into contact with the chemical, they may experience an upset stomach or lose their appetite.
Ridding your garden of weeds can feel like a never-ending battle, but commercial grade weed killers offer professional results with the affordability of domestic weed killers.
