Iron thorns, also known as devil’s thorn or goathead weed, are a problematic weed in many areas. Their thorny seed heads can puncture bike tires and injure pet paws. They grow in disturbed areas and can be tough to control. In this blog post, we will discuss where you can find iron thorns and how to control them.
iron thorns location are found throughout the United States, preferring hot and dry climates. They are found primarily on the western side of the US, in states like California, New Mexico, Arizona, and Texas. They are also found in the southern states like Florida and Georgia. You can find them growing in fields, vacant lots, roadsides, and along streams.
Iron thorns can be tough to control, but there are ways to manage them. One of the easiest ways to prevent their spread is to simply remove them before they go to seed. The thorny seed heads spread easily, so it’s important to dispose of them in a sealed bag or container. Mowing or weed eating can also help control them, but the blades need to be very sharp to effectively cut through the tough stems and thorns.
Chemical control is also an option for managing iron thorns. Pre-emergent herbicides can be used to prevent the seeds from germinating. Post-emergent herbicides can be used to kill the plants after they have emerged. Be sure to follow all label instructions carefully and wear protective clothing when applying herbicides.
In addition to chemical control, there are biological control methods that can be used. A species of weevil, native to South America, has been introduced as a biological control agent for iron thorns. The weevils feed on the seeds and can reduce the number of seeds produced by up to 90 percent. This method has been successful in some areas but may not be effective for controlling large infestations.
Lastly, education and prevention are key in managing iron thorns. Raising awareness about the problems caused by the weed and encouraging people to remove the weed before the seed head mature can go a long way in reducing the spread of this invasive species.
In short:
Iron thorns are a problematic weed that can cause damage to pets, bike tires, and other outdoor equipment. They are found throughout the United States, primarily in hot and dry climates. Managing iron thorns can be challenging, but there are several options for controlling their spread, including removing them before they go to seed, using chemical or biological control methods, and educating others about their impact. By following these guidelines, we can reduce the impact of this invasive species and keep outdoor spaces safe and enjoyable.
