Roundup is the brand name of a herbicide that controls most weeds and grasses. This product entered the market in the 1970s. Since then, gardeners (both private and commercial) have been using this product for several years. 

This treatment is non-selecting, meaning it will kill most plants and sometimes even trees. It works by preventing essential proteins from reaching the plant’s roots, which will eventually cause its death.

While the research seems to have different views on the subject, Roundup won’t harm animals or humans. But will this product kill a privet hedge?

Roundup and Privet Hedge: Will It Work to Remove it? 

To keep the story short: yes, Roundup can kill your privet hedge. However, you’ll only have satisfactory results if you know how to apply it. And the adequate measures will depend on your objective. 

For instance, if your goal is to limit the spread of your hedge (without killing it), you should spray its foliage with the herbicide. But if you want to get rid of your privet hedge, you’ll have to apply the treatment to the bark. You’ll have to use a concentrate and put it on the stems too to guarantee a satisfactory result.

Alternatively, you can apply Roundup to the stump with a brush (after cutting down your privet hedge to the ground). Doing so will also minimize the dispersion of the chemicals and prevent harm to other plants in your garden.
