How To Kill Stinkweed Plants

Stinkweed plants are a common problem for gardeners and homeowners. These invasive plants can quickly take over your lawn or garden, and their unpleasant odor can be a nuisance. Fortunately, there are several effective ways to kill stinkweed plants and prevent them from coming back. In this article, we'll explore some of the best methods for getting rid of stinkweed.

What is Stinkweed?

Before we dive into how to kill stinkweed plants, let's first define what they are. Stinkweed, also known as field pennycress, is a weed that belongs to the mustard family. It grows up to 3 feet tall and has small white flowers. As its name suggests, stinkweed has a strong, unpleasant odor that can be especially noticeable after it has been mowed or disturbed.

Manual Removal

One of the most effective ways to get rid of stinkweed is through manual removal. This involves physically pulling the plants out of the ground by hand, making sure to remove as much of the root system as possible. Manual removal is best done when the soil is moist, as it will be easier to pull the plants out without breaking the roots. Remember to wear gloves to protect your hands from any potential skin irritation caused by the plant's oils!

Chemical Control

If manual removal isn't an option or if you have a large area to treat, chemical control may be a better solution. Herbicides containing glyphosate are particularly effective against stinkweed. Before applying any herbicides, make sure to read and follow the instructions on the label carefully. You should also wear protective clothing and avoid spraying on windy days to prevent drift onto other plants.

Vinegar Solution

If you prefer a more natural approach, you can try using a vinegar solution to kill stinkweed. Mix white vinegar with water in a 1:1 ratio and add a few drops of dish soap to help the solution stick to the leaves. Spray the solution directly onto the stinkweed plants, making sure to thoroughly coat the leaves. Keep in mind that this method may take longer to produce results than chemical herbicides.

Mulching

Mulching around your plants can also help to prevent stinkweed from growing. Cover the soil with a layer of mulch, such as wood chips, straw, or leaves, to create a barrier that prevents stinkweed seeds from germinating. This method won't kill existing stinkweed plants, but it can help to prevent new ones from growing in the future.
