What is Horsenettle?

Horsenettle is a perennial weed that tends to grow in colonies. It thrives in various soil conditions and will adapt to different lighting. Horsenettle displays tough and woody stems that are generally hard to remove.

Take prompt action to eliminate it from your garden to avoid suffering in the future. Indeed, these plants attract harmful pests that like to chew on plants’ leaves, especially tomatoes, potatoes, and eggplant. 

Additionally, horsenettle might cause the appearance of destructive viruses that might affect your crops. 

The plant might grow up to three feet tall. Luckily, it isn’t challenging to identify: its leaves are oval with lobed margins and contain prickles. It will produce flowers in the spring and summer, followed by yellow berries.

Can You Use Roundup to Kill Horsenettle?

Horsenettle spreads fast and aggressively thanks to its deep rhizomes. Roundup is an excellent method to kill this plant. Spray the product in late spring or summer (the weed’s growing season) to get satisfactory results. Don’t worry if you don’t notice any immediate effect.

Usually, Roundup takes about two weeks before reaching horsenettle’s roots. 

Don’t forget that Roundup is a non-selective herbicide, meaning it might harm other plants. Always follow the instructions on the product’s label to increase the product’s effectiveness and reduce harm to your garden.

What Else Can You Do To Remove Horsenettle? 

As we mentioned before, horsenettle is hard to remove. As soon as you notice its presence, consider hand-pulling it. Mowing and tilling usually have little to no effect. 

After applying Roundup, pull the plants to eliminate the infestation. If the problem persists, apply herbicides containing aminopyralid or picloram. Don’t forget that you most likely won’t be able to get rid of horsenettle from a single application. Instead, keep applying it until you don’t see any weeds on your lawn.
