Pampas Grass

Before anything else, let us first talk about what exactly is pampas grass. This is a South American grass that is recognizable for its height and flowering plumes. There are many people who consider this as an excellent addition to their landscape as this is an ornamental grass. However, they can also be invasive. Especially because of their height, they can sometimes be an eyesore. This is the part wherein the rest of this post will come handy. Learn about some of the things that you can do to effectively get rid of pampas grass in the garden.

Effective Ways to Kill Pampas Grass

Among others, one of the best solutions you might want to consider is trimming or pruning. They can grow up to 10 feet, so cutting it from the top can be a bit of a challenge. According to experts in gardening, it will be good if you can retain its height to only three feet, or even shorter. To do this, simply grab a bunch of pampas grass in your palm and prune it with your chosen shear. This will make it easier to make sure that they are cut at the same height.

What exactly does trimming do to kill pampas grass? We understand that you might think that it has not been killed, it was just pruned. It is still alive, but the difference is that it is shorter. Well, apparently, a single plant can produce as much as 10,000 seeds. When the wind blows, they can be taken as far as 20 miles, or even just within your garden. This means that the seed can soon propagate, and before you notice it, pampas grass is out of control. With this, cutting the tip will get rid of the seed and will lessen the likelihood that they will grow more.

Aside from trimming, the application of an herbicide will also be an effective solution. This, however, will only be effective once the stalks have already been trimmed, which means that the flower has been removed. If there are plants around the area, you can use a paintbrush to make sure that only the pampas grass will be covered. Within two weeks, the grass will dry.

While the use of an herbicide can be effective, keep in mind that this will depend on a number of factors. For instance, you should choose one that is glyphosphate-based. Also, you have to pay attention to the instructions from the manufacturer on how it is used and on the concentration that is recommended. You should also not forget to wear gloves and goggles as protection from the possible toxicity coming from the herbicide.

Once the grass has died following the application of herbicide, there are basically two things that you can do. For people who seem to be too lazy, they often end up just leaving it on the ground. After all, since it is already dead, it would basically just decompose. For others, meanwhile, they opt to pull the grass manually, especially if they cannot wait for the grass to rot since they would like to start planting already.


Now that you are done reading, we hope that you have learned from the simple tips above on how to kill pampas grass. It is not a complicated task and you do not need to have the luxury of time to have it accomplished. However, be sure to do this carefully, especially when you have to deal with herbicides. If you are using herbicides, you might end up killing not just pampas, but other plants that surround the grass.
