For those who haven't dealt with puncturevine yet, don't worry, it is coming your way soon. Here is a map from the U of Georgia showing current distribution.
puncturevine (Tribulus terrestris) - EDDMapS State Distribution - EDDMapS
I got out early this morning to look over my puncturevine garden, hoping the latest chemical application is doing some good. The last batch was Roundup Super Concentrate (50% glyphosphate with included surfactant). After my experience with several other herbicides, I increased the poison to water dilution in this mix.
The good news: the poison is killing the plant. The bad news: the seeds have already set and are scattered far and wide on the ground. Next spring I'll get out early with a pre-emergent herbicide and see whether I can finish this off. From what I read, the seeds can lay dormant for several years before sprouting, which means I may have a new hobby.

@ponytug recommended I try Grampa's Weeder (
Grampa's Weeder - The Original Stand Up Weed Remover). I already have the device, so took it with me this morning. When I was able to sink the prongs into the ground it was really effective, but the soil is so thin and the ground so rocky that it is nearly a useless effort. Plus, there is no way to get those seeds from the cracks and crevices of the rocky ground.
Then when I took off my work boots in the shop, I saw the soles were loaded with thorns. Makes me wonder how many new plants I seeded on the way to the house.
In spite of it all, I wouldn't trade a day in the country for anything the city has to offer. If I want to, I can drive to the city to get what I need and be back home in just a few minutes. I'd rather wrangle with rocks and marmots and puncturevine than a neighbor who doesn't like the color I painted my fence.
