How do you get rid of vine like plant with stickers called "Goatheads"?

These plants grow very close to the ground, (too close for lawn mowers,) and spread across the ground like a vine. The leaves are a small round shape and the color is dark green. The stickers themselves are flat, rounded at one end, with three spears/prongs on them. We have tried weed and feed, pre- emergent, and we have even killed all of the grass in the yard trying to just get rid of everything and start over. I feel terrible for my dog, she has a little path that she makes around the yard, zig zagging back and forth thru the "safe zone." Not to mention every time we walk in the house with no shoes on, you're asking for it. I vacuum every day, and still keep finding those darn stickers!! Help!

How do you get rid of vine like plant with stickers called "Goatheads"?
You can use a herbicide or pre-emergent. From a website:



Goathead weeds, so called because of their spiny seeds, are more correctly called "puncture vine." This is important to know because you will find no herbicides labeled for "goathead", rather you will find them for "puncture vine".



Pre-emergent herbicides labeled to control puncture vine can be applied in the spring before the puncture vine weeds begin to germinate. Such herbicides work by killing the seedling as it germinates. They will not kill existing plants, only those just germinating from seeds. Read and carefully follow the label directions to get the maximum benefit.



Once the puncture vine has germinated and is growing, a "broad-leaf" (post-emergent herbicide) may be used. Again, follow the directions. You can supplement this with manual removal (digging or pulling the weeds). It is important to prevent the weeds from forming seeds, so diligence is required. If seeds do form successfully, that is the source of a problem for subsequent years. Even if a few plants do manage to form seeds, if you can limit the number formed you can reduce next year's problem. Since the seed can remain viable in the soil for several years, you must continue vigilant management until no live seeds remain in the soil to create problems.



For more detailed information and recommendations specifically for your area, contact your local Cooperative Extension Service Agent or Master Gardeners. Many nurseries and plant centers can also provide information and help you read and understand the herbicide labels so that you can select one appropriate for your location and conditions.
Reply:I can sympathize, when I lived in CO I tried everything so I'm not sure what killed them. I sometimes think it was just from tromping around in my bare feet OOCH OOCH ,OWCH OWCH. RScott
