Commercial Weed Killer Buyer’s Guide

Commercial grade weed killers are the strongest on the market, eliminating almost any type of weed from both commercial and domestic spaces. If you’re struggling to eliminate the weeds in your garden, a commercial weed killer is your best bet.

Not sure what to look for when it comes to the best commercial strength weed killer? Check out this buyer’s guide.

Ingredients

Most commercial grade weed killers will contain glyphosate. This is an exceptionally strong chemical that will help eliminate most domestic weeds. Weed killers with 360g/l glyphosate are the most effective.

Cheaper weed killers will contain less glyphosate but these may be less effective on more mature weeds. Younger weeds won’t need as much glyphosate.

Coverage

The coverage area will save you money long term. If you have a lot of weeds to tackle, you should opt for a weed killer with a wide coverage area to get the most value for money.

Results

The speed of results will vary, but most commercial grade weed killers should offer visible results in a few days at the most. More mature weeds may require another application, but most weeds should be fully eliminated with just one application.

If you need to rid your garden of weeds quickly, look for a weed killer that delivers speedy results. Many claim you can begin reseeding and replanting the area where the weeds were growing in just a few days.

Safety

Commercial grade weed killers are extremely strong and for many people, safety is a concern. If you have kids or pets, safety is even more important. If you are worried, look for a pet-safe commercial grade weed killer.

Ensure you purchase from a reputable manufacturer and store the chemical out of reach of children. Wear protective gear when applying the weed killer, and wash your hands after touching any plants that have been sprayed with it. Follow the manufacturer’s instructions when it comes to application and dilution ratios.

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. 

Conclusion

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. For its wide coverage and easy application, the Elixir Gardens Barclay 2L Weed Killer is our top recommendation for the best commercial grade weed killer.
