The Science Behind Roundup Weed Killer

The most advanced weedkiller on earth

Roundup is full of very smart stuff.

It was originally developed for use on a large scale in the agricultural industry.

And the exact same advanced technology that's used in the commercial sector is called upon to create Roundup for gardens, patios and driveways.

It incorporates a highly effective systemic action that has a dramatic effect on any weed but because Roundup is deactivated in the soil by micro organisms the soil is free to use as soon as the Roundup has dried.

Absorbed by the leaves, Roundup circulates down to the weed’s growing points. So, even though, outwardly, there might not be many signs that the weed is affected, apart from some yellowing of shoots and leaves, rest assured that Roundup is getting to work on the plant.

Put simply, Roundup is killing the plants from ‘inside out’.

Here’s how it works:

  • Roundup is sprayed on to the leaves of the weed
  • It’s absorbed through the leaves and enters the plant’s sap stream
  • Roundup is carried to the growing points of the weed’s roots and shoots
  • The first effects become visible after 48 hours (6 hours in the case of Roundup Fast Action). 
  • Roundup kills the leaves, shoots and roots
  • Soil is left ready for replanting

Because it kills right down to the root, Roundup will eradicate almost all weeds, including hard to kill weeds, such as Bamboo, Couch, Nutgrass, and Oxalis.

Why have weeds re-grown after several weeks?

Only deep-rooted rhizomatous weeds may re-grow. This will only happen if too little Roundup has been allowed to penetrate the full plant system. In this instance, a re-treatment will be required.

Why has it killed the grass?

Because Roundup is a non selective weedkiller, that means that Roundup is very effective at killing all plants. So be careful to only spray weeds or plants that you don’t want to keep.

Can it be used on paving?

Yes definitely, Roundup is ideal for use on paving, paths and drives as it penetrates right to the weeds roots to ensure a complete kill.
